About

This site indexes LLM API relays and gateways that offer free quota. Data is open as structured JSON and can be fetched with curl. The goal is to help developers find free access quickly.

Inclusion criteria

This site only lists LLM relays/gateways that offer a free tier: signup credit, free tokens, daily check-in, some free models, or unlimited free usage. Services without any free tier are excluded.

13 relays and 42 models indexed

JSON endpoints

Data is served as static JSON (models.dev-compatible) and can be fetched with curl, with short-lived caching (1h browser / 1d CDN):

/api.json

Keyed by relay id: free quota, auth, pricing, providers and the model subset

curl https://models.denohub.com/api.json

/models.json

Keyed by model id: context, modalities, reasoning specs and auto-computed available_on

curl https://models.denohub.com/models.json

/catalog.json

Both combined, fetch once

curl https://models.denohub.com/catalog.json
