## How to call these APIs

- AGL OTA API: `Authorization` header token plus an AGL-issued `clientId` header. `language` and
  `currency` are required query parameters on every read.
- AGL OPEN API: `Authorization: Bearer <SHA-256 hashed signature>` plus `X-Supplier-Code`
  (supplier→AGL) or `X-Client-Code` (AGL→supplier). The signing canonicalization is not published.
- Trip.com bridge: JWT bearer plus `ClientId`, `Currency` and `Language` headers, with a signed
  request-header object in the body.

## Things an agent should know before acting

- **HTTP 200 is not success on the OTA API.** It declares only 200 responses; failures arrive as
  `CommonResponse.status == "fail"` with codes `FL00`, `FL01` or `ET00`.
- **No idempotency.** Ten mutating operations, zero replay protection. A retried reservation
  request creates a second hold.
- **Reversal is available and the window is data.** `POST /v2/reservation/request` returns a
  `CancellationPolicy` whose `policies[]` carry `appliesUntil` cut-offs and fee percentages. Read
  them before `POST /v2/reservation/confirm`, which takes payment.
- **Tee times cannot be updated.** AGL's own contract says so: set the existing one unavailable via
  `PUT /api/teetime/availability`, then re-register via `POST /api/teetime/daily`.
- **No sandbox.** The AGL OPEN API declares `https://sandbox-agl-bridgeapi.tigergds.com` but the
  host does not resolve (NXDOMAIN, 2026-09-12).
- **No published rate limits, status page, deprecation policy, changelog, SDK, CLI, MCP server or
  A2A agent card.**
