OpenAPI Specification

openapi: 3.2.0
info:
  title: HEDGR public MCP API
  version: 1.0.0
  description: HEDGR is the AI FX agent for SME finance teams. This document covers the genuinely public, unauthenticated surface (health checks, public rates, OAuth discovery metadata) plus the MCP endpoint agents use to call Hedgr's read-only dashboard tools. The authenticated /api/* dashboard namespace used by the Hedgr web app is intentionally not enumerated here - see https://hedgr.app/developer-docs for why.

    strategy: header

    response_header: Every /api response carries `Hedgr-API-Version` naming the contract that answered it.
    request_pinning: A client MAY pin by sending `Hedgr-API-Version`. An unrecognised value is rejected with 400 and a typed ApiError rather than silently served the current shape, so a pin is never quietly ignored.
    mcp: The MCP endpoint versions separately, per request, via the JSON-RPC `protocolVersion` field. GET /mcp lists every accepted version in `protocolVersions`; POST /mcp with method=initialize negotiates one and echoes the agreed value.
    deprecation: A version being retired is announced on its responses with the standard `Deprecation` (RFC 9745) and `Sunset` (RFC 8594) headers before removal, and in CHANGELOG.md. Versions are added append-only; an older version keeps serving until its Sunset date passes.
    breaking_change_definition: Removing or renaming a field, narrowing a type, or changing an existing status code. Adding a new optional field is not breaking and does not bump the version.
