# List All Available Models on KiosAPI — GET /v1/models

> GET /v1/models — lists all models available to your API key. Supports OpenAI Bearer, Anthropic x-api-key, and Google x-goog-api-key auth formats.

Call `GET /v1/models` to retrieve every model your KiosAPI key can access. The endpoint is OpenAI-compatible and accepts all three authentication header formats — OpenAI `Authorization: Bearer`, Anthropic `x-api-key`, and Google `x-goog-api-key` — so you can reuse whichever client library you already have in place without restructuring your auth flow.

## Request

**Endpoint:** `GET https://kiosapi.com/v1/models`

### Headers

| Header              | Format          | Description                                                    |
| ------------------- | --------------- | -------------------------------------------------------------- |
| `Authorization`     | `Bearer sk-xxx` | OpenAI-style auth header                                       |
| `x-api-key`         | `sk-xxx`        | Anthropic-style auth header                                    |
| `anthropic-version` | `2023-06-01`    | Required alongside `x-api-key` when using Anthropic-style auth |
| `x-goog-api-key`    | `sk-xxx`        | Google-style auth header                                       |

<Info>
  At least one authentication header is required. You do not need to supply all three — choose the format that matches your preferred client library.
