# Get a model

GET https://api.respan.ai/api/models/{model_name}/

Retrieve a built-in or custom model by model name. Custom models are only visible to the owning organization.

Reference: https://respan.ai/docs/apis/models/get-model

## Authentication

- `Authorization` header (bearer token, required) — Use your Respan API key for Respan API authentication. Enter only the Respan API key value; clients send Authorization: Bearer \<RESPAN\_API\_KEY>. For /api/responses, provider credentials such as Perplexity, OpenAI, or Azure OpenAI go in Settings -> Providers or respan\_params.credential\_override in the request body, not in this authentication field.
- `Authorization` header (bearer token, required) — Use a dashboard JWT only for dashboard-authenticated endpoints. Respan API-key endpoints use the respanApiKey auth field instead.

## Request

### Path parameters

- `model_name` (string, required) — The `model_name` that List models returns. Built-in models are provider-prefixed, such as `openai/gpt-4o-mini`; bare names such as `gpt-4o-mini` return 404.

- `output_cost` (double, optional) — Cost per 1M output tokens in USD.
- `cache_hit_input_cost` (double, optional) — Cost per 1M cached input tokens in USD.
- `cache_creation_input_cost` (double, optional) — Cost per 1M cache creation input tokens in USD.
- `max_context_window` (integer, optional) — Maximum context window size.
