> [!NOTE]
>
> **中国本土のユーザー向け：** 中国本土のユーザーは `https://toapis.cn` を API エンドポイント（Base URL）としてご利用ください。本ドキュメント内の例では `https://toapis.com` を `https://toapis.cn` に置き換えてください。

The platform provides two API formats. Use the `model` parameter to switch models:

| API Format | エンドポイント | 説明 |
| - | - | - |
| **Chat Completions** (default) | `POST /v1/chat/completions` | Classic chat API, compatible with OpenAI SDKs. [View docs](https://docs.toapis.com/docs/ja/api-reference/chat/chat.md) |
| **レスポンスs** (new) | `POST /v1/responses` | Newer OpenAI agentic API with function calling, built-in tools, and server-side multi-turn context. [View docs](https://docs.toapis.com/docs/ja/api-reference/chat/responses.md) |

> [!TIP]
>
> モデル marked as `レスポンスs Only` only support the レスポンスs API and do not support Chat Completions. Other models are called through Chat Completions by default.
