Crawl vs Map

Use Crawl when:

• Full content extraction needed
• Building RAG systems
• Processing paginated/nested content
• Integration with knowledge bases

Use Map when:

• Quick site structure discovery
• URL collection without content
• Planning before crawling
• Sitemap generation

---

Key Parameters

---

Instructions and Chunks

Use instructions and chunks_per_source for semantic focus and token optimization:

response = client.crawl(
    url="https://docs.example.com",
    max_depth=2,
    instructions="Find all documentation about authentication and security",
    chunks_per_source=3  # Only top 3 relevant chunks per page
)

Key benefits:

• instructions guides crawler semantically, focusing on relevant content
• chunks_per_source returns only relevant snippets (max 500 chars each)
• Prevents context window explosion in agentic use cases
• Chunks appear in raw_content as: <chunk 1> [...] <chunk 2> [...] <chunk 3>

Note: chunks_per_source only works when instructions is provided.

---

Path and Domain Filtering

Path patterns (regex)

# Target specific sections
response = client.crawl(
    url="https://example.com",
    select_paths=["/docs/.*", "/api/.*", "/guides/.*"],
    exclude_paths=["/blog/.*", "/changelog/.*", "/private/.*"]
)

# Paginated content
response = client.crawl(
    url="https://example.com/blog",
    max_depth=2,
    select_paths=["/blog/.*", "/blog/page/.*"],
    exclude_paths=["/blog/tag/.*"]
)

Domain control (regex)

# Stay within subdomain
response = client.crawl(
    url="https://docs.example.com",
    select_domains=["^docs.example.com$"],
    max_depth=2
)

# Exclude specific domains
response = client.crawl(
    url="https://example.com",
    exclude_domains=["^ads.example.com$", "^tracking.example.com$"]
)

---

Use Cases

1. Deep/Unlinked Content

Deeply nested pages, paginated archives, internal search-only content.

response = client.crawl(
    url="https://example.com",
    max_depth=3,
    max_breadth=50,
    limit=200,
    select_paths=["/blog/.*", "/changelog/.*"],
    exclude_paths=["/private/.*", "/admin/.*"]
)

2. Documentation/Structured Content

Documentation, changelogs, FAQs with nonstandard markup.

response = client.crawl(
    url="https://docs.example.com",
    max_depth=2,
    extract_depth="advanced",
    select_paths=["/docs/.*"]
)

3. Multi-modal/Cross-referencing

Combining information from multiple sections.

response = client.crawl(
    url="https://example.com",
    max_depth=2,
    instructions="Find all documentation pages that link to API reference docs",
    extract_depth="advanced"
)

4. Rapidly Changing Content

API docs, product announcements, news sections.

response = client.crawl(
    url="https://api.example.com",
    max_depth=1,
    max_breadth=100
)

5. RAG/Knowledge Base Integration

response = client.crawl(
    url="https://docs.example.com",
    max_depth=2,
    extract_depth="advanced",
    include_images=True,
    instructions="Extract all technical documentation and code examples"
)

6. Compliance/Auditing

Comprehensive content analysis for legal checks.

response = client.crawl(
    url="https://example.com",
    max_depth=3,
    max_breadth=100,
    limit=1000,
    extract_depth="advanced",
    instructions="Find all mentions of GDPR and data protection policies"
)

7. Known URL Patterns

Sitemap-based crawling, section-specific extraction.

response = client.crawl(
    url="https://example.com",
    max_depth=1,
    select_paths=["/docs/.*", "/api/.*", "/guides/.*"],
    exclude_paths=["/private/.*", "/admin/.*"]
)

---

Map then Extract Pattern

Consider using Map before Crawl/Extract to plan your strategy:

1. Use Map to get site structure 2. Analyze paths and patterns 3. Configure Crawl or Extract with discovered paths 4. Execute focused extraction

# Step 1: Map to discover structure
map_result = client.map(
    url="https://docs.example.com",
    max_depth=2,
    instructions="Find all API docs and guides"
)

# Step 2: Filter discovered URLs
api_docs = [url for url in map_result["results"] if "/api/" in url]
guides = [url for url in map_result["results"] if "/guides/" in url]
print(f"Found {len(api_docs)} API docs, {len(guides)} guides")

# Step 3: Extract from filtered URLs
target_urls = api_docs + guides
response = client.extract(
    urls=target_urls[:20],  # Max 20 per extract call
    extract_depth="advanced",
    query="API endpoints and usage examples",
    chunks_per_source=3
)

Benefits:

• Discover site structure before committing to full crawl
• Identify relevant path patterns
• Avoid unnecessary extraction
• More control over what gets extracted

---

Performance Optimization

Depth vs Performance

Each depth level increases crawl time exponentially:

Best practices:

• Start with max_depth=1 and increase only if needed
• Use max_breadth to control horizontal expansion
• Set appropriate limit to prevent excessive crawling
• Process results incrementally rather than waiting for full crawl

Rate Limiting

• Respect site's robots.txt
• Monitor API usage and limits
• Use appropriate error handling for rate limits
• Consider delays between large crawl operations

Conservative vs Comprehensive

# Conservative (start here)
response = client.crawl(
    url="https://example.com",
    max_depth=1,
    max_breadth=20,
    limit=20
)

# Comprehensive (use carefully)
response = client.crawl(
    url="https://example.com",
    max_depth=3,
    max_breadth=100,
    limit=500
)

---

Common Pitfalls

Summary

1. Use instructions and chunks_per_source for focused, relevant results in agentic use cases 2. Start conservative (max_depth=1, max_breadth=20) and scale up as needed 3. Use path patterns to focus crawling on relevant content 4. Choose appropriate extract_depth based on content complexity 5. Always set a limit to prevent runaway crawls and unexpected costs 6. Monitor failed_results and adjust patterns accordingly 7. Use Map first to understand site structure before committing to full crawl 8. Implement error handling for rate limits and failures 9. Respect robots.txt and site policies

Crawling is powerful but resource-intensive. Focus your crawls, start small, monitor results, and scale gradually based on actual needs.

Extraction Approaches

Search with include_raw_content

Get search results and content in one call:

response = client.search(
    query="AI healthcare applications",
    include_raw_content=True,
    max_results=5
)

When to use:

• Quick prototyping
• Simple queries where search results are likely relevant
• Single API call convenience

Direct Extract API (Recommended)

Two-step pattern for more control:

# Step 1: Search
search_results = client.search(
    query="Python async best practices",
    max_results=10
)

# Step 2: Filter by relevance score
relevant_urls = [
    r["url"] for r in search_results["results"]
    if r["score"] > 0.5
]

# Step 3: Extract with targeting
extracted = client.extract(
    urls=relevant_urls[:20],
    query="async patterns and concurrency",  # Reranks chunks
    chunks_per_source=3  # Prevents context explosion
)

for item in extracted["results"]:
    print(f"URL: {item['url']}")
    print(f"Content: {item['raw_content'][:500]}...")

When to use:

• You want control over which URLs to extract
• You need to filter/curate URLs before extraction
• You want targeted extraction with query and chunks_per_source

---

Key Parameters

---

Query and Chunks

Use query and chunks_per_source to get only relevant content and prevent context window explosion:

extracted = client.extract(
    urls=[
        "https://example.com/ml-healthcare",
        "https://example.com/ai-diagnostics",
        "https://example.com/medical-ai"
    ],
    query="AI diagnostic tools accuracy",
    chunks_per_source=2  # 2 most relevant chunks per URL
)

When to use query:

• To extract only relevant portions of long documents
• When you need focused content instead of full page extraction
• For targeted information retrieval from specific URLs

Key benefits of chunks_per_source:

• Returns only relevant snippets (max 500 chars each) instead of full page
• Chunks appear in raw_content as: <chunk 1> [...] <chunk 2> [...] <chunk 3>
• Prevents context window from exploding in agentic use cases

Note: chunks_per_source only works when query is provided.

---

Extract Depth

# For complex pages
extracted = client.extract(
    urls=["https://example.com/complex-page"],
    extract_depth="advanced"
)

Fallback strategy: If basic fails, retry with advanced:

result = client.extract(urls=[url], extract_depth="basic")
if url in [f["url"] for f in result.get("failed_results", [])]:
    result = client.extract(urls=[url], extract_depth="advanced")

Timeout tuning: If latency isn't critical, set timeout=60.0 for better success on slow pages.

---

Advanced Filtering Strategies

Beyond query-based filtering, consider these approaches before extraction:

Optimal Workflow

1. Search to discover relevant URLs 2. Filter by relevance score, domain, or content snippet 3. Re-rank if needed using specialized models 4. Extract from top-ranked sources with query and chunks_per_source 5. Validate extracted content quality 6. Process for your AI application

Example: Complete Pipeline

import asyncio
from tavily import AsyncTavilyClient

client = AsyncTavilyClient()

async def content_pipeline(topic):
    # 1. Search with sub-queries for breadth
    queries = [
        f"{topic} overview",
        f"{topic} best practices",
        f"{topic} recent developments"
    ]
    responses = await asyncio.gather(
        *(client.search(q, search_depth="advanced", max_results=10) for q in queries)
    )

    # 2. Filter and aggregate by score
    urls = []
    for response in responses:
        urls.extend([
            r['url'] for r in response['results']
            if r['score'] > 0.5
        ])

    # 3. Deduplicate
    urls = list(set(urls))[:20]

    # 4. Extract with error handling
    extracted = await asyncio.gather(
        *(client.extract(urls=[url], query=topic, extract_depth="advanced")
          for url in urls),
        return_exceptions=True
    )

    # 5. Filter successful extractions
    return [e for e in extracted if not isinstance(e, Exception)]

asyncio.run(content_pipeline("machine learning in healthcare"))

Summary

1. Use query and chunks_per_source for targeted, focused extraction 2. Choose Extract API when you need control over which URLs to extract from 3. Filter URLs before extraction using scores, re-ranking, or domain trust 4. Choose appropriate extract_depth based on content complexity 5. Process URLs concurrently with async operations for better performance 6. Implement error handling to manage failed extractions gracefully 7. Validate extracted content before downstream processing

• Key Parameters
• Basic Usage
• Streaming vs Polling

• Response Fields
• Summary

---

Overview

The Research API conducts comprehensive research on any topic with automatic source gathering, analysis, and response generation with citations. It's an end-to-end solution when you need AI-powered research without building your own pipeline.

---

Prompting Best Practices

Define a clear goal with all details and direction.

Guidelines:

• Be specific when you can. Include known details: target market, competitors, geography, constraints
• Stay open-ended only for discovery. Make it explicit: "tell me about the most impactful AI innovations in healthcare in 2025"
• Avoid contradictions. Don't include conflicting constraints or goals
• Share what's already known. Include prior assumptions so research doesn't repeat existing knowledge
• Keep prompts clean and directed. Clear task + essential context + desired output format

Example Queries

Company research:

Research the company ____ and its 2026 outlook. Provide a brief overview
of the company, its products, services, and market position.

Competitive analysis:

Conduct a competitive analysis of ____ in 2026. Identify their main
competitors, compare market positioning, and analyze key differentiators.

With prior context:

We're evaluating Notion as a potential partner. We already know they
primarily serve SMB and mid-market teams, expanded their AI features
significantly in 2025, and most often compete with Confluence and ClickUp.
Research Notion's 2026 outlook, including market position, growth risks,
and where a partnership could be most valuable. Include citations.

---

Model Selection

Pro Model

Multi-agent research suited for complex topics spanning multiple subtopics or domains. Use for deeper analysis, thorough reports, or maximum accuracy.

result = client.research(
    input="Analyze the competitive landscape for ____ in the SMB market, "
          "including key competitors, positioning, pricing models, customer "
          "segments, recent product moves, and defensible advantages or risks "
          "over the next 2-3 years.",
    model="pro"
)

Mini Model

Optimized for targeted, efficient research. Best for narrow or well-scoped questions where you still benefit from agentic searching and synthesis.

result = client.research(
    input="What are the top 5 competitors to ____ in the SMB market, and how do they differentiate?",
    model="mini"
)

---

Key Parameters

research()

get_research()

---

Basic Usage

Research tasks are two-step: initiate with research(), retrieve with get_research().

import time
from tavily import TavilyClient

client = TavilyClient()

# Step 1: Start research task
result = client.research(
    input="Latest developments in quantum computing and their practical applications",
    model="pro"
)
request_id = result["request_id"]

# Step 2: Poll until completed
response = client.get_research(request_id)
while response["status"] not in ["completed", "failed"]:
    print(f"Status: {response['status']}... polling again in 10 seconds")
    time.sleep(10)
    response = client.get_research(request_id)

# Step 3: Handle result
if response["status"] == "failed":
    raise RuntimeError(f"Research failed: {response.get('error', 'Unknown error')}")

report = response["content"]
sources = response["sources"]

---

Streaming vs Polling

Streaming — Best for user interfaces where you want real-time updates. Polling — Best for background processes where you check status periodically.

Streaming

Enable real-time progress monitoring with stream=True.

stream = client.research(
    input="Latest developments in quantum computing",
    model="pro",
    stream=True
)

for chunk in stream:
    print(chunk.decode('utf-8'))

Event Types

Tool Types

Typical Flow

1. Planning tool_call → tool_response 2. WebSearch tool_call → tool_response (with sources) 3. ResearchSubtopic cycles (Pro mode only) 4. Generating tool_call → tool_response 5. Content chunks (markdown or structured JSON) 6. Sources event 7. Done event

See streaming cookbook and polling cookbook for complete examples.

---

Structured Output vs. Report

Structured Output

Use output_schema to receive research in a predefined JSON structure.

schema = {
    "type": "object",
    "properties": {
        "summary": {
            "type": "string",
            "description": "Executive summary of findings"
        },
        "key_points": {
            "type": "array",
            "items": {"type": "string"},
            "description": "Main takeaways from the research"
        },
        "metrics": {
            "type": "object",
            "properties": {
                "market_size": {"type": "string", "description": "Total market size"},
                "growth_rate": {"type": "number", "description": "Annual growth percentage"}
            }
        }
    },
    "required": ["summary", "key_points"]
}

result = client.research(
    input="Electric vehicle market analysis 2024",
    output_schema=schema
)

Schema Best Practices

• Write clear field descriptions. 1-3 sentences explaining what the field should contain
• Match the structure you need. Use arrays, objects, enums appropriately (e.g., competitors: string[], not "A, B, C")
• Avoid duplicate fields. Keep each field unique and specific
• Use `required` arrays to enforce mandatory fields at any nesting level

Supported types: object, string, integer, number, array

Streaming with Structured Output

When output_schema is provided, content arrives as structured JSON:

stream = client.research(
    input="AI agent frameworks comparison",
    model="mini",
    stream=True,
    output_schema={
        "type": "object",
        "properties": {
            "summary": {"type": "string", "description": "Executive summary"},
            "key_points": {"type": "array", "items": {"type": "string"}}
        },
        "required": ["summary", "key_points"]
    }
)

for chunk in stream:
    data = chunk.decode('utf-8')
    print(data)  # Content chunks will be structured JSON

---

Response Fields

research() Response

get_research() Response

Source Object

---

Summary

1. Be specific in prompts — Include known details: target market, competitors, geography, constraints 2. Share prior context — Include what you already know to avoid repetition 3. Choose the right model — mini for focused queries, pro for comprehensive multi-domain analysis 4. Use streaming for UX — Display real-time progress during long research tasks 5. Use structured output for pipelines — Define schemas for consistent, parseable responses 6. Use reports for reading — Default format is best for chat interfaces and sharing

Query Optimization

Keep queries under 400 characters. Think search query, not long-form prompt.

Break complex queries into sub-queries:

# Instead of one massive query, break it down:
queries = [
    "Competitors of company ABC",
    "Financial performance of company ABC",
    "Recent developments of company ABC"
]
responses = await asyncio.gather(*(client.search(q) for q in queries))

Search Depth

Controls the latency vs. relevance tradeoff:

Content types:

• Content: NLP-based summary of the page, providing general context
• Chunks: Short snippets (max 500 chars) reranked by relevance to your query

When to use each:

• ultra-fast: Latency-critical (real-time chat, autocomplete)
• fast: Need chunks but latency matters
• basic: General-purpose, balanced relevance and latency
• advanced: Specific information queries, precision matters (still fast and suitable for almost all use cases)

Key Parameters

Notes:

• `include_answer`: Only use if you don't want to bring your own LLM. Most users bring their own model.

• `auto_parameters`: May set search_depth="advanced" (2 credits). Set search_depth manually to control cost.

Basic Usage

from tavily import TavilyClient

client = TavilyClient()

response = client.search(
    query="latest developments in quantum computing",
    max_results=10,
    search_depth="advanced",
    chunks_per_source=5
)

for result in response["results"]:
    print(f"{result['title']}: {result['url']}")
    print(f"Score: {result['score']}")

Filtering Results

By domain

# Only search trusted sources
response = client.search(
    query="machine learning best practices",
    include_domains=["arxiv.org", "github.com", "pytorch.org"],
)

# Exclude specific domains
response = client.search(
    query="openai product reviews",
    exclude_domains=["reddit.com", "quora.com"]
)

# Restrict to LinkedIn profiles
response = client.search(
    query="CEO background at Google",
    include_domains=["linkedin.com/in"]
)

By date

# Relative time range
response = client.search(query="latest ML trends", time_range="month")

# Specific date range
response = client.search(
    query="AI news",
    start_date="2025-01-01",
    end_date="2025-02-01"
)

By country

# Boost results from specific country
response = client.search(query="tech startup funding", country="united states")

Async Patterns

Leveraging the async client enables scaled search with higher breadth and reach by running multiple queries in parallel. This is the best practice for agentic systems where you need to gather comprehensive information quickly before passing it to a model for analysis.

import asyncio
from tavily import AsyncTavilyClient

# Initialize Tavily client
tavily_client = AsyncTavilyClient("tvly-YOUR_API_KEY")

async def fetch_and_gather():
    queries = ["latest AI trends", "future of quantum computing"]

    # Perform search and continue even if one query fails (using return_exceptions=True)
    try:
        responses = await asyncio.gather(*(tavily_client.search(q) for q in queries), return_exceptions=True)

        # Handle responses and print
        for response in responses:
            if isinstance(response, Exception):
                print(f"Search query failed: {response}")
            else:
                print(response)

    except Exception as e:
        print(f"Error during search queries: {e}")

# Run the function
asyncio.run(fetch_and_gather())

Response Fields

Top-level response:

Each result object:

Top-level response also includes:

Each image object (if `include_images=True`):

Post-Filtering Strategies

Since Tavily provides raw web data, you have full configurability to implement filtering and post-processing to meet your specific requirements.

The score field measures query relevance, but doesn't guarantee the result matches specific criteria (e.g., correct person, exact product, specific company). Use post-filtering to validate results against strict requirements.

Score-Based Filtering

Simple threshold filtering based on relevance score:

results = response["results"]

# Filter by score threshold
high_quality = [r for r in results if r["score"] > 0.7]

# Sort by score
sorted_results = sorted(results, key=lambda x: x["score"], reverse=True)

# Top N above threshold
top_relevant = sorted(
    [r for r in results if r["score"] > 0.5],
    key=lambda x: x["score"],
    reverse=True
)[:3]

Limitation: Score indicates relevance to query, not accuracy of match to specific criteria.

Regex Filtering

Fast, deterministic filtering using pattern matching. Use for:

• URL pattern validation
• Required keywords/phrases
• Structural requirements

import re

def regex_filter(result, criteria: dict) -> dict:
    """
    Filter a search result using regex checks.

    Args:
        result: Search result dict with url, content, title, raw_content
        criteria: Dict with patterns to match:
            - url_pattern: Regex for URL validation
            - required_terms: List of terms that must appear in content
            - excluded_terms: List of terms that must NOT appear

    Returns:
        dict with check results and validity
    """
    url = result.get("url", "")
    content = result.get("content", "") or ""
    title = result.get("title", "") or ""
    raw_content = result.get("raw_content", "") or ""

    full_text = f"{content} {title} {raw_content}".lower()

    checks = {}

    # URL pattern check
    if "url_pattern" in criteria:
        checks["url_valid"] = bool(re.search(criteria["url_pattern"], url.lower()))

    # Required terms check
    if "required_terms" in criteria:
        checks["required_found"] = all(
            re.search(re.escape(term.lower()), full_text)
            for term in criteria["required_terms"]
        )

    # Excluded terms check
    if "excluded_terms" in criteria:
        checks["excluded_absent"] = not any(
            re.search(re.escape(term.lower()), full_text)
            for term in criteria["excluded_terms"]
        )

    # Valid if all checks pass
    is_valid = all(checks.values()) if checks else True

    return {"checks": checks, "is_valid": is_valid, "url": url}

Example: LinkedIn Profile Search

criteria = {
    "url_pattern": r"linkedin\.com/in/",  # Profile URL, not company page
    "required_terms": ["Jane Smith", "Acme Corp"],
    "excluded_terms": ["job posting", "careers"]
}

for result in response["results"]:
    validation = regex_filter(result, criteria)
    if validation["is_valid"]:
        print(f"Valid: {validation['url']}")

Example: GitHub Repository Search

criteria = {
    "url_pattern": r"github\.com/[\w-]+/[\w-]+$",  # Repo URL, not file
    "required_terms": ["MIT License"],
    "excluded_terms": ["archived", "deprecated"]
}

LLM Verification

Semantic validation using an LLM. Use for:

• Synonym/abbreviation matching ("FDE" = "Forward Deployed Engineer")
• Context-aware validation
• Confidence scoring with reasoning

from openai import OpenAI
import json

def llm_verify(result, target_description: str, validation_criteria: list[str]) -> dict:
    """
    Use LLM to verify if a search result matches target criteria.

    Args:
        result: Search result dict
        target_description: What you're looking for
        validation_criteria: List of criteria to check

    Returns:
        dict with is_match, confidence (high/medium/low), reasoning
    """
    content = result.get("content", "") or ""
    title = result.get("title", "") or ""
    url = result.get("url", "")

    criteria_text = "\n".join(f"- {c}" for c in validation_criteria)

    prompt = f"""Verify if this search result matches the target.

Target: {target_description}

Validation Criteria:
{criteria_text}

Search Result:
URL: {url}
Title: {title}
Content: {content}

Does this result match ALL criteria?

Respond with JSON only:
{{"is_match": true/false, "confidence": "high/medium/low", "reasoning": "brief explanation"}}"""

    client = OpenAI()
    response = client.chat.completions.create(
        model="gpt-4o-mini",
        messages=[{"role": "user", "content": prompt}],
        response_format={"type": "json_object"}
    )

    return json.loads(response.choices[0].message.content)

Example: Profile Verification

result = llm_verify(
    result=search_result,
    target_description="Jane Smith, Software Engineer at Acme Corp",
    validation_criteria=[
        "Name matches Jane Smith",
        "Currently works at Acme Corp (or recently)",
        "Role is software engineering related",
        "Professional customer-facing experience"
    ]
)

if result["is_match"] and result["confidence"] in ["high", "medium"]:
    print(f"Verified: {result['reasoning']}")
