- Track orders and communicate with sellers
Authentication, headers & limits
Authentication
Public endpoints: Product catalog, stock browsing, contact forms. Authenticated endpoints: Cart, orders, addresses, payments — require JWT or API Key via Authorization: Bearer <JWT> or X-Api-Key: <API_KEY>. ACP and MCP both forward these to the backend.
Optional headers
X-Request-ID: request correlation (generated if not provided). X-Agent-ID: optional agent identifier. Both are returned in response headers and ACP response metadata.
Limits
Request body max 1 MB. Backend request timeout 60 s; tool calls returning after that get 504. Clients can cancel with AbortController.
