## Model API Integration

1折AI provides Claude and OpenAI / GPT APIs, supporting Anthropic Messages, OpenAI Responses, and Chat Completions. Common endpoints include Anthropic's native `/v1/messages` and OpenAI-compatible `/v1/chat/completions`. The code and tools you already have generally only need two changes: the Base URL and the API key.

```text
Anthropic Base URL   https://1zheai.com
OpenAI Base URL      https://1zheai.com/v1
API Key    sk-...（在控制台创建）
```

Claude input and output are billed at each model's discounted rate; cache reads and cache writes are billed at the official original price with no discount. Prices and billing units for GPT, MiMo, and image generation models are listed in [Models and Pricing](https://1zheai.com/en/pricing/).

<Note>

Claude, GPT, MiMo, and image generation models are live; the full list is in [Supported Models](/en/docs/models/).
