# BookingTruth - booking assurance for agents

> Verify whether a travel booking is real, confirmed, and ticketed - before you or your user gets stranded at a desk. CONFIRMED is returned only on supplier-authoritative evidence; anything weaker returns an honest UNKNOWN with the indicated state and a citable proof packet.

## Endpoints
- Discovery doc: https://bookingtruth.com/.well-known/booking-assurance.json
- OpenAPI 3.0: https://bookingtruth.com/v1/openapi.yaml
- MCP server (streamable HTTP): https://bookingtruth.com/mcp
- POST /v1/check - documents (emails/receipts text) in, verdicts + proof packets out
- GET /v1/bookings/{id} and /v1/bookings/{id}/proof - verdict summary and citable proof
- GET /v1/coverage - suppliers parsed today (seeded vs planned)
- GET /v1/demo/fixtures - free sample documents to try

## Auth and pricing
- Sandbox: free, any Bearer key starting with sb_ - full round trip, fixtures provided
