Built for developers & AI agents

Everything an app or an autonomous agent needs to integrate in minutes.

OpenAPI 3.1 spec

A complete, machine-readable openapi.yaml — import it into any client generator, SDK, or agent tool.

llms.txt

A plain-text map of the API for LLMs: llms.txt and the fuller llms-full.txt with every endpoint and example.

Agent-ready CLI

A zero-dependency CLI that prints clean JSON to stdout — trivial to pipe into jq or call from an agent. Install npm i -g fitvete-food-cli (npm · docs).

Frequently asked questions

Is there a free tier?

Yes — the Free plan is $0/month with 50 points per day, access to every endpoint, and no credit card required.

How do I authenticate?

Send your API key in the x-api-key header (or as an ?apiKey= query parameter) on every request. Keys look like fv_live_….

What is the base URL?

All endpoints live under https://auth.fitvete.com/functions/v1/food-api at /v1/. Responses are JSON and include X-RateLimit-* headers.

What can the API do?

Search foods, compute full nutrition for an ingredient list, look up barcodes, search recipes and drinks, parse a plain-English meal, score a food A–F, suggest healthier swaps, analyze ingredient labels, and estimate nutrition from a meal photo or Nutrition Facts label.

Can AI agents use it?

Yes — there's an OpenAPI 3.1 spec, an llms.txt guide, and a zero-dependency CLI that prints clean JSON for easy parsing.
