description: Food Info serves harmonised nutrient data for reference foods over a versioned REST API.
  It merges six food-composition datasets — USDA FoodData Central, McCance & Widdowson's CoFID, ANSES
  Ciqual, DTU Frida, AUSNUT and Open Food Facts — into a single schema, so a caller can query nutrients
  across sources without reconciling each publisher's format. Endpoints cover food search, a full nutrient
  panel per food, a nutrient catalogue, reverse nutrient search for the richest and poorest reference
  foods, and recipe parsing and analysis that resolves raw ingredient lines into per-line nutrition. Authentication
  is an X-Api-Key header, with a free tier of 10 requests a minute and 100 a day. HTTPS only and CORS
  disabled, so it is built for server-to-server use. The underlying dataset carries a citable Zenodo DOI,
  which is unusual provenance for a commercial data API.

X-Discovery:
  date: '2026-08-04'
  method: probed
  note: Requested in api-search/inbox#2. Every claim checked before profiling.
  findings:
  - surface: OpenAPI
    url: https://api.food-info.org/api/v1/openapi.json
    http_status: 200
    real: true
    note: OpenAPI 3.0.4, 8 operations, 24 schemas, X-Api-Key, real server. All 8 operations carry an operationId
      as of the 2026-08-04 re-harvest — added by the provider the same day the gap was raised in api-search/inbox#2.
  - surface: LlmsTxt
    url: https://food-info.org/llms.txt
    http_status: 200
    real: true
    note: 8,462 bytes — LIVE. The submission said none was published; the provider confirmed it is server-generated
      rather than static, which is why it was overlooked. Re-fetched 2026-08-04 and byte-identical to
      the copy held.
  - surface: DatasetDOI
    url: https://doi.org/10.5281/zenodo.21527348
    http_status: 200
    real: true
    note: Resolves to Zenodo; a citable dataset record.
  - surface: DataSources
    url: https://food-info.org/data-sources
    http_status: 200
    real: true
  - surface: WellKnown
    url: https://food-info.org/.well-known/api-catalog
    http_status: 404
    real: false
    note: No RFC 9727 api-catalog on either host. A re-probe on 2026-08-04 did find an RFC 9116
      security.txt at https://food-info.org/.well-known/security.txt (200) and a Content-Signal
      declaration in robots.txt; both are captured in well-known/.
  - surface: Control
    url: https://food-info.org/zzz-control-nonsense
    http_status: 404
    real: false
    note: Both hosts 404 correctly on a control path — no SPA catch-all, so the probes above are trustworthy.
  reharvests:
  - date: '2026-08-04'
    trigger: Provider reply on api-search/inbox#2
    note: Provider added operationIds to all 8 operations and confirmed the llms.txt. Spec re-fetched
      from the first-party source and archived verbatim to openapi/_original/.
