openapi: 3.2.0
info:
  title: Aard REST Tools API
  version: 1.0.0
  summary: Official economic and statistical data from 170+ publishers, resolved from natural language over plain HTTP.
  description: 'Four tools — `discover`, `inspect`, `ask`, `build_url` — each a `POST /v1/{tool}` taking one flat JSON object of arguments and returning the same output the MCP tool of that name produces. The tools return catalogue metadata and exact publisher requests, never observations: execute a returned plan client-side and query the parsed file locally.


    Authenticate with an API key minted at https://aard.ai/account/keys, sent as `Authorization: Bearer aard_live_…`. MCP OAuth tokens are not accepted here. Keys are bound to the account''s plan: its tool entitlements and monthly call cap (https://aard.ai/pricing). A call is charged only when the origin answers with a result — a 4xx, 429 or 502 is refunded rather than charged. The API is server-to-server: `/v1/*` sends no CORS headers, so a browser-hosted client cannot call it directly.


    Every `/v1/{tool}` response carries `X-Aard-Request-Id`. Every error is `{"ok": false, "error": ""[, "detail": "…"]}`; a 400 for an unknown or missing parameter name lists every accepted name in `detail`, so one round trip is enough to correct a call.


    Request schemas are transcribed from the origin''s validator (gsdmx2 0cee9034, 2026-09-17); the origin''s own contract test re-checks this document against that validator. The MCP surface at https://api.aard.ai/mcp carries six further tools, including bounded server-side dataset retrieval; see https://aard.ai/mcp.'
