Interactive OpenAPI 3.1 reference for the Sendero tool registry. Mint a key, call a tool, watch the nanopayment settle on Arc.

Every callable Sendero surface is one URL away.

Live OpenAPI 3.1 document — /api/openapi.json. Scalar, Redoc, Postman, Insomnia, and curl consume it as-is. Generated from the canonical tool registry in packages/tools/src/openapi.ts, so drift between code and docs is impossible.
Interactive browser — launch the Scalar viewer →. Try any tool against a live sandbox key, copy-paste the curl for production.
MCP parity — every tool is also live on the MCP server at /api/mcp. Same schemas, same auth, same pricing.
LLM-friendly exports — append .md to any docs page for raw markdown the way Sherpa exposes their "Trips LLM Friendly" endpoint. Example: /docs/tools/search_flights.md. Or pull the full crawl manifest at /llms.txt.

Mint a key before you try it. Every request carries a Clerk-issued API key on Authorization: Bearer. Production keys are one click at /dashboard/settings/api-keys — no form, no gating, no sales call. Sandbox keys are auto-issued on tenant creation and never move real USDC.

Dispatch shape

Every tool is reachable at POST /api/agent/dispatch with one body shape. The server derives the service-account subject (svc:${keyId}) from the key, so userId never rides on the wire.

curl -X POST https://app.sendero.travel/api/agent/dispatch \
  -H "Authorization: Bearer ak_live_…" \
  -H "Content-Type: application/json" \
  -d '{
    "tenantId": "tenant_abc123",
    "tool": "search_flights",
    "args": {
      "origin": "SFO",
      "destination": "LHR",
      "departureDate": "2026-06-15",
      "passengers": 1,
      "cabinClass": "business"
    }
  }'

Response includes { ok, result, latencyMs, priceMicroUsdc } — the settled nanopayment amount is right there in the response, auditable.

How to use the docs programmatically

Point a coding agent at any of:

Surface	URL	What it's for
OpenAPI 3.1	`/api/openapi.json`	Full tool registry, machine-readable, cacheable
LLM manifest	`/llms.txt`, `/.well-known/llms.txt`	Endpoint roots + per-surface crawl hints
Per-page markdown	append `.md` to any `/docs/*` URL	Plain-text source for LLM ingestion
MCP tools/list	`/api/mcp` (JSON-RPC)	Agent-native protocol, same auth

Each URL returns Access-Control-Allow-Origin: *, Cache-Control: max-age=3600 where it makes sense.

Every call bills one x402 nanopayment in micro-USDC. See packages/tools/src/pricing.ts for the canonical per-tool price and /docs/pricing for plan-tier discount rules (Pro tier cuts nanopayments 30%, Enterprise 50%).

Changelog highlights

2026-04-24 — Published canonical /api/openapi.json generated from the tool registry. Added per-page .md exports (append .md to any docs URL). Added top-nav Get API key deep link. Added check_travel_eligibility for visa/passport verdicts and scan_document for receipt/invoice/boarding-pass OCR. Shipped @sendero/sherpa with the vendored Sherpa Requirements API v3 spec.
2026-04-23 — Duffel tool names abstracted (*_duffel_* → *_flight_*) so supplier IP stays out of public MCP/docs/LLM surfaces.
2026-04-17 — Dispatch auth migrated to Clerk native API keys (GA'd April 17, 2026). Self-service key minting replaces the gated form pattern most of our peers still use.
