API reference

List models

Returns the models your key is allowed to use, which is not necessarily the whole catalog if the key is scoped.

GET/v1/models

The response shape follows whichever protocol you appear to be speaking. Send anthropic-version and you get Anthropic's list shape; otherwise you get OpenAI's. Both describe the same models.

curl https://api.overagent.cc/v1/models \

This endpoint is authenticated but free, which makes it the cheapest way to check that a key is live. For prices and context windows, see the catalog.
