# Model Info Lookup

`GET /utils/model_info`

## Request

- Base URL: `https://api.sea-lion.ai` (the document declares no server; this is the origin it was published from)
- URL: `https://api.sea-lion.ai/utils/model_info`

Returns the model cost map entry (token limits, pricing, supports_* capabilities) for any model

(`key`, `supported_openai_params`).

```
curl -X GET --location 'http://localhost:4000/utils/model_info?model=gpt-4o&custom_llm_provider=openai'         --header "Authorization: Bearer $LITELLM_MASTER_KEY"
