Public model catalog

Site-wide model catalog with USD list prices, no key required; any site may read it cross-origin, cached for 5 minutes.

GET/api/v1/models/pricing

No key required. Any site may read the response cross-origin, and it is cached for up to 5 minutes (Cache-Control: public, max-age=300).

Prices are USD list prices before the group multiplier; the price you actually pay for each model is in the signed-in model catalog. To see only which models a key can call, use GET /v1/models.

data[].platform is the protocol family the model is served under (for example openai, claude, gemini, kling), not the model vendor; see vendor for that. A model offered through several groups may appear under several platform values. For field details see Account and catalog API.
