# ResultRail by LarryBuildsAI Product Card

ResultRail is a pay-per-success data rail for AI agents and a standalone LarryBuildsAI product.

## Buyer

Agents that need one source-attributed public domain or URL result without creating another vendor account.

| Tool | Price | Buyer Outcome |
|---|---:|---|
| `quote_data_result` | `$0.001` | Free pre-payment quote for one ResultRail public-data result. Returns price, paid endpoint, success contract, and whether the buyer's max price covers the result. |
| `enrich_domain_result` | `$0.12` | Fetch a public domain/homepage and return one source-attributed result pack: company/title/description, industry guess, technographic signals, useful paths, confidence, sources, and receipt hash. |
| `extract_url_result` | `$0.05` | Fetch one public URL and return title, description, headings, text preview, links, confidence, source URL, and receipt hash. Designed for pay-per-success agent extraction. |

Discovery: `https://proofbeforepay.vercel.app/resultrail/mcp`, `/.well-known/resultrail-x402`, `/resultrail/openapi.json`, `/.well-known/resultrail-mcp.json`.

Quote price: free on the direct ResultRail MCP endpoint; the xpay wrapper uses a `$0.001` minimum because the xpay dashboard does not accept a literal free tool price.

## Public Proof

- mcpservers.org: approved/live public listing.
- Smithery: rendered page, no-query markdown, and cache-busted catalog checks are repaired.
- MCP.so: public listing page returns `200`, but the canonical proofbeforepay ResultRail MCP URL is not propagated yet; dashboard ownership/control is still not claimed.
- MCPHubz: public metadata repo is ready and the ResultRail submit form is prepared, but the final submit action still requires explicit approval; no listing claim yet.

## Limits

Public web data only. ResultRail is not private enrichment, guaranteed extraction, web-scale crawling, or a replacement for account-bound provider APIs.

Product boundary: ResultRail is its own product. Do not merge it with Signal Desk, GateCheck, Boundary Guard x402, or x402 Resource Scanner in listings.

Claim boundary: ResultRail returns public-data result packs with source URLs, timestamps, confidence, and receipt hashes. It does not sell private contact databases, bypass access controls, provide legal/financial advice, send outreach, place bets, trade assets, or guarantee downstream revenue.
