Rate limits

No API key is required. The tool uses USDA's DEMO_KEY (50 requests/day per IP) and Open Food Facts (unlimited, no key needed).

If you hit the USDA rate limit, get a free personal key in 30 seconds:

1. Sign up at https://fdc.nal.usda.gov/api-key-signup
2. Run: nutrition config set --usda-key YOUR_KEY

This raises your limit to 1,000 requests/hour.

Data sources

• USDA FoodData Central — generic foods (SR Legacy, Foundation) and branded products. US government data, high quality.
• Open Food Facts — community-contributed product database with barcode lookup, Nutri-Score, NOVA classification, allergen data, and vegan/vegetarian status.

The CLI prefers USDA SR Legacy/Foundation results for generic food queries and falls back to Open Food Facts automatically.
