Get a model (Anthropic format)

GET
/v1/models/{model_id}

Returns one model, looked up by canonical id or alias. The response always carries the canonical id.

Canonical ids contain a slash, which must be URL-encoded here: /v1/models/anthropic%2Fclaude-opus-5-5. The Anthropic SDKs encode it for you. Aliases need no encoding: /v1/models/claude-opus-5-5. An unencoded slash gets a 404.

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.

Path Parameters

model_id*string

A canonical model id (with its slash encoded as %2F) or an alias.

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.

Response Body

The model.

application/json
  1. response
type*string

The canonical model id.

created_at*string

When the model was added to EZAT Router (not its release date).

List models (Anthropic format) GET

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.

List models (OpenAI format) GET

Lists the models your key can use, in OpenAI's format: the same models as `GET /v1/models`, with canonical `author/model` ids. `owned_by` is the part of the id before the slash.
