Quickstart

Purpose: help you ship a first successful API call and know where to go next.

An API is a simple way for your app to talk to LogMeal over the internet—your app sends a request (e.g., an image), and the API returns structured results in json format (e.g., recognized foods and nutrition).

Prerequisites

1. Create an account & subscribe — start with 🆓 Free (Trial). All features are enabled while you test.
   👉 Sign up for free now at LogMeal Signup Page

2. Get your first 🔴 APIUser & copy its token. After signup, by default, a testing APIUser was created for you at LogMeal Users Page.

3. Acquire or download some food images. You can download a ready-to-use sample image for testing purposes here.

Need a refresher on plans, limits, and user types? See Plans & Limits (©, (D), (S) ⏱), and User Types & Access Tokens (⚫ APICompany, 🔴 APIUser, 🔵 APIUserManager).

The 10‑minute flow

You’ll do three tiny tasks:

1. Recognize an image → get imageId and dish candidates.
2. Fetch ingredients information associated to the image.
3. Fetch nutritional information associated to the image.

1) Recognize an image

Upload a meal photo and run the Complete Segmentation endpoint to detect dishes and regions.

• Token required: 🔴 APIUser
• Pick your preferred path:
  • No code: try it in the interactive docs: POST /v2/image/segmentation/complete
  • With code: paste a ready-to-run snippet:
    Image-based Food Recognition

    Open Recipe

Tip: If you’re unsure, start with the interactive docs to verify your token and payload, then switch to the recipe for integration.

✅ You now have an imageId to use in the next steps.

2) Fetch ingredients information and quantities

After recognition, show the list of ingredients and quantities associated to the recognized dishes.

• Token required: 🔴 APIUser
• Pick your preferred path:
  • No code: try it in the interactive docs: POST /v2/nutrition/recipe/ingredients
  • With code: paste a ready-to-run snippet:
    Retrieve Ingredients & Quantities

    Open Recipe

3) Fetch nutritional details

Show detailed nutritional information report for the recognized image.

• Token required: 🔴 APIUser
• Pick your preferred path:
  • No code: try it in the interactive docs: POST /v2/nutrition/recipe/nutritionalInfo
  • With code: paste a ready-to-run snippet:
    Retrieve Nutritional Information

    Open Recipe
