Overview

The Chomp API provides detailed nutritional data for millions of grocery products and restaurant menu items, including macros, ingredients, and allergen flags. You authenticate with an API key passed in the request header, and responses come back as clean JSON. It is a great fit for food-tracking apps, recipe tools, or any project that needs reliable packaged-food nutrition data.

Beginner Tip

Search by UPC barcode (e.g., 016000275287) for the most accurate match — product name searches can return multiple results for similar items.

Common Errors & Troubleshooting

401 Unauthorized API key is missing or placed in the wrong location.
✓ Pass the key in the x-api-key request header, not as a query parameter.
Empty items array The product name is too specific or contains brand spelling variations.
✓ Try a shorter, more generic search term or switch to a UPC lookup using the code parameter.
429 Too Many Requests Free-tier accounts have a low monthly request limit.
✓ Cache nutrition results by UPC in a local database so each product is only fetched once.
