  title: Resolve a food name to a NutrientsDB record and read its nutrient profile
  version: 1.0.0
  description: >-
    Two-step flow over the free, keyless NutrientsDB Sample API: search the public 1,000-food sample
    by name fragment, then re-fetch the chosen record by its stable public_id. Both steps use the
    single published operation, findFoods, selected by q or by id. No authentication is required.

    summary: Search the sample by food name, then retrieve the selected food by public_id.

      Step 1 searches by name fragment and returns up to 20 matches with total_matches so the caller
      knows how many were withheld. Step 2 pins the chosen record by its stable public_id, which is
      the identifier to persist — food names are verbose and ambiguous, ids are not.

          Retrieve the selected food by its exact public_id. q and id are mutually exclusive, so this
          step sends only id.
