List models (Anthropic format)

GET
/v1/models

Lists the models your key can use, in Anthropic's format, with canonical author/model ids. A key restricted to some models lists only those. Deprecated models are listed while they are still served; models in preview only for keys allowed to use them.

Every model comes in one page: has_more is always false, and the limit, before_id and after_id query parameters are ignored.

Authorization

headerx-api-key<token>

Your EZAT Router key (ezat_sk_…) in the x-api-key header, as the Anthropic SDKs send it. Accepted on every /v1 and /openai/v1 endpoint.

Header Parameters

anthropic-version?string

Accepted for compatibility with Anthropic's SDKs, which send it, but not used. You don't need to send it.
