Essential Concepts

Plans & Limits

Explore the different LogMeal Subscription Plans and choose the one that meets your needs. Understand API request limits: monthly credits, daily request limits and per‑second request limits.

User Types & Access Tokens

Roles and tokens for account admins, end-users and nutrition-related managers — who calls which endpoints and how to authenticate.

Images Pre‑processing

Image guidelines that improve recognition quality (size, format, lighting, etc.).

Implement a Use Case

Image-based Food Recognition with User Confirmation

Capture a meal photo, get top dish predictions, and let the user confirm/refine results before saving. Confirmations feed the food recognition personalization capabilities.

Ingredients List Retrieval

Retrieve standardized recipe ingredients and quantities for confirmed dishes from a food intake.

Nutritional Information Retrieval

Extract per‑dish macro & micro nutrients from a confirmed intake using standardized ingredients.

Food Quantity Detection

Capture a depth‑based image sequence around food items to estimate their quantities using the Quantity Detection API.

Food Quantity Confirmation

Confirm how much was eaten (grams or Small/Medium/Big portion) and auto‑recalculate ingredients & nutrition.

Units of Measurement & User Preferred Measurements

Adapt measures to user preferences (metric/imperial, cooking measures, portions) while keeping grams as the source of truth.
