Food lookup

ctx.FOOD finds packaged food in Open Food Facts, from the digits on a barcode or the name on the label.

Methods

Method	Input	Returns
`lookupBarcode`	`{ barcode }`	One product, or `null`
`search`	`{ name }`	Up to three matching products

Returns


{
  barcode: "6001275000013",
  name: "Jungle Oats",
  brand: "Jungle",
  servingSize: "40 g",
  per100g: { kcal: 368, protein: 12, carbs: 60, sugar: 1, fat: 8, saturatedFat: 1.4, fibre: 10, salt: 0 },
  perServing: { kcal: 147, protein: 4.8, carbs: 24, sugar: 0.4, fat: 3.2, saturatedFat: 0.6, fibre: 4, salt: 0 },
  allergens: ["gluten"],
  nutriScore: "A",
  read: "Jungle Oats has 147 kcal per 40 g serving. Contains gluten.",
}

read is one or two plain sentences a loop can send as they are. Any nutrient can be null when the label doesn’t give it.

Use it


import { workflow } from "@loops/sdk";
 
type Barcode = { barcode: string };
 
export const foodWorkflow = workflow<Barcode>({
  id: "food-lookup",
  execute: async ({ step, event }) =>
    step.do("Look up the product", ({ ctx }) =>
      ctx.FOOD.lookupBarcode({ barcode: event.body.barcode }),
    ),
});

What it won’t invent

Home-cooked food isn’t in the database, so an empty result is the expected answer there. Any figures a loop gives instead are an estimate, and it should say so.
