Data Enrichment

Data Enrichment with x402 APIs

STOP — Read before making any API call. enrichx402.com endpoints are not the same as each provider's native API. All paths use the format https://enrichx402.com/api/{provider}/{action}. You MUST either:

1. Copy exact URLs from the Quick Reference table below, OR

2. Run x402.discover_api_endpoints(url="https://enrichx402.com") to get the correct paths

>

Guessing paths will fail with 405 errors (wrong path) or 404 errors (missing /api/ prefix).

Use the x402scan MCP tools to access enrichment APIs at enrichx402.com.

Setup

See rules/getting-started.md for installation and wallet setup.

Quick Reference

Workflows

Standard Enrichment

1. (Optional) Check balance: x402.get_wallet_info 2. Discover endpoints (required before first fetch): x402.discover_api_endpoints(url="https://enrichx402.com") 3. Check endpoint schema: x402.check_endpoint_schema(url="...") to verify parameters and pricing 4. Call endpoint with x402.fetch using exact URL from discovery or Quick Reference table above 5. Parse and present results

x402.fetch(
  url="https://enrichx402.com/api/apollo/people-enrich",
  method="POST",
  body={"email": "user@company.com"}
)

Person Enrichment

x402.fetch(
  url="https://enrichx402.com/api/apollo/org-enrich",

  body={
    "domain": "stripe.com"
  }
)

    "person_titles": ["CTO", "VP Engineering"],
    "organization_domains": ["google.com", "meta.com"],
    "person_locations": ["San Francisco, CA"]

    "email": "john@example.com"
  }
)

Bulk Operations

Process up to 10 records in one request:

x402.fetch(
  url="https://enrichx402.com/api/apollo/people-enrich/bulk",
  method="POST",
  body={
    "people": [
      { "email": "person1@company.com" },
      { "email": "person2@company.com" },
      { "linkedin_url": "https://linkedin.com/in/person3" }
    ]
  }
)

For companies:

x402.fetch(
  url="https://enrichx402.com/api/apollo/org-enrich/bulk",
  method="POST",
  body={
    "organizations": [
      { "domain": "company1.com" },
      { "domain": "company2.com" }
    ]
  }
)

Cost Optimization

Field Filtering

Reduce costs by excluding unneeded fields:

body={
  "email": "john@company.com",
  "excludeFields": ["employment_history", "photos", "phone_numbers"]
}

Common fields to exclude:

• employment_history - Past jobs (often large)
• photos - Profile images
• phone_numbers - If you only need email
• social_profiles - If you don't need social links

Bulk vs Individual

• Individual: $0.0495 per record
• Bulk (10): $0.495 total = $0.0495 per record

Bulk is the same price per record but faster for multiple items.

Search Before Enrich

Use search endpoints ($0.02) to find the right records before enriching ($0.0495):

1. Search for candidates: /api/apollo/people-search 2. Review results, pick the right match 3. Enrich only the matches you need

Parallel Calls

When enriching multiple independent records, make calls in parallel:

# These can run simultaneously since they're independent
x402.fetch(url=".../people-enrich", body={"email": "a@co.com"})
x402.fetch(url=".../people-enrich", body={"email": "b@co.com"})

Or use bulk endpoints for the best efficiency.

Handling missing data

If any query fails to return the data you are looking for, revist the list of available APIs.

Oftentimes, if apollo is missing data, clado will have it, and vice versa.

If those still fail, use built-in WebSearch and WebFetch tools to find additional information like a company domain name or LinkedIn URL, and then use that data to make more targeted queries.

Getting Started

Setup

1. Install the x402scan MCP:

   npx @x402scan/mcp install --client claude-code -y

2. Check wallet:

   x402.get_wallet_info

3. Fund wallet (if needed):

• Redeem invite: x402.redeem_invite(code="YOUR_CODE")
• Or use the deposit UI (point the user towards this URL: https://x402scan.com/mcp/deposit/<their-wallet-address>)
