Request body

food_idstring required

FatSecret food id

quantitynumber required
unitstring required

Unit label (g, oz, each, large, …)

serving_idstring

FatSecret serving_id the user picked from the food's servings array. When provided, the recompute uses THAT serving's per-serving nutrition and metric reference instead of the FS default. Required for foods whose servings are not linear scalings of each other (raw vs cooked, with-skin vs without, piece vs volume) — without it, preview anchors on the wrong baseline. When the id does not match any serving the food currently exposes, falls back to the FS default and logs a warning.

regionstring

FatSecret region override. Currently advisory only — getFoodDetails is region-agnostic, so the value is echoed back in the response but does not affect the FS lookup. Matches createFoodLog/editFoodLog behavior. Reserved for future region-scoped lookups.

Example request

{
  "food_id": "12345",
  "quantity": 70,
  "unit": "g",
  "serving_id": "57969",

}
