Start by reading /llms.txt. Then connect to the MCP endpoint at https://edge.sendero.travel/mcp and call initialize followed by tools/list. For a real booking, prefer the sendero.book_flight workflow instead of manually chaining tools. The workflow searches Duffel, checks policy, reserves prepaid escrow, holds the offer, waits for ticketing, settles the booking, and generates the invoice.
Direct HTTP clients can call /tools/:name with x402 Payment-Signature headers. Use safe identifiers such as tenantId, userId, tripId, bookingId, and runId. Never persist guest private-link fragments, plaintext claim codes, raw card data, seed phrases, or API secrets.
