Get a model (Anthropic format)
GET
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.
