ResultRail By LarryBuildsAI
Pull pay-per-success public-data packs—domain enrichment, URL facts, technographics—for agents without juggling multiple API keys.
Overview
ResultRail is an MCP server for the Build phase that provides pay-per-success public-data result packs with provenance for AI agent enrichment workflows.
What is this MCP server?
- Pay-per-success public data result packs routed through MCP for AI agents
- Use cases in metadata: domain enrichment, URL extraction, public company facts, technographic lookup
- Result packs include source URLs, timestamps, confidence, and receipt hashes per claim boundary
- x402 manifest and well-known MCP discovery on proofbeforepay.vercel.app
- Explicit limits: no private contact databases, access-control bypass, outreach, trading, or revenue guarantees
- Product title ResultRail by LarryBuildsAI
- Separate from Signal Desk and GateCheck in registry metadata
- x402Manifest and wellKnownMcp URLs on proofbeforepay.vercel.app
What problem does it solve?
Agents stall on research tasks when every enrichment source needs its own API key, contract, and error handling.
Who is it for?
Solo builders automating company or domain research inside agents who accept public-data limits and want metered pay-per-success access.
Skip if: Teams needing verified private contact lists, regulated financial advice, or guaranteed enrichment coverage behind login walls.
What do I get? / Deliverables
After registration, your agent can request bounded public-data packs with receipts and confidence metadata, paying only on successful results via x402.
- Public-data result packs with source URLs and confidence
- Receipt hashes suitable for audit trails in agent runs
- Enrichment outputs for domain, URL, and company-fact tasks without per-vendor API key sprawl
Recommended MCP Servers
Journey fit
During build, agents need trustworthy external data hooks; ResultRail supplies integration-shaped MCP access with x402 billing. Integrations subphase covers third-party data routers agents call mid-workflow, not your own database schema design.
How it compares
Pay-per-success public data MCP router, not a seller readiness gate like GateCheck.
Common Questions / FAQ
Who is ResultRail for?
Indie builders and agent authors who need domain, URL, and company fact enrichment through MCP without managing many separate data API subscriptions.
When should I use ResultRail?
Use it during build/integrations when an agent workflow needs sourced public facts with timestamps and receipt hashes, and you are fine with x402 metered successful calls.
How do I add ResultRail to my agent?
Install io.github.LarryLemonBot/resultrail from the MCP registry and configure your client using the well-known MCP and x402 manifest URLs published at proofbeforepay.vercel.app for ResultRail.
