# Anthropic Models API — 模型查询

Source: https://ofox.io/zh/docs/api/anthropic/models

通过 Anthropic 原生协议查询 OfoxAI 平台上可用的模型。响应格式遵循 Anthropic API 规范（`type`、`display_name`、`created_at` 等字段）。

Models API 是公开接口，无需 API Key 即可调用。此端点返回所有可通过 Anthropic 协议调用的模型，不仅限于 Claude 系列。

## 列出所有模型

```http
GET https://api.ofox.io/anthropic/v1/models
```

### 请求示例

```bash filename="Terminal"
curl https://api.ofox.io/anthropic/v1/models
```

### 响应格式

### 与 OpenAI 协议的字段差异

| 字段 | OpenAI 协议 | Anthropic 协议 |
|------|------------|----------------|
| 类型标识 | `"object": "model"` | `"type": "model"` |
| 名称 | `name` | `display_name` |
| 创建时间 | `created`（Unix 时间戳） | `created_at`（ISO 8601） |

## 按供应商过滤模型

```http
GET https://api.ofox.io/anthropic/v1/models/{provider}
```

### 路径参数

| 参数 | 类型 | 说明 |
|------|------|------|
| `provider` | string | 供应商标识，如 `anthropic`、`openai`、`google` |

### 请求示例

```bash filename="Terminal"
# 仅列出 Claude 系列模型
curl https://api.ofox.io/anthropic/v1/models/anthropic
```

### 响应格式

返回格式与列出所有模型一致，`data` 数组仅包含指定供应商的模型。

## 获取模型详情

```http
GET https://api.ofox.io/anthropic/v1/models/{provider}/{model_id}
```

### 路径参数

| 参数 | 类型 | 说明 |
|------|------|------|
| `provider` | string | 供应商标识，如 `anthropic` |
| `model_id` | string | 模型名称，如 `claude-sonnet-5.5` |

### 请求示例

```bash filename="Terminal"
curl https://api.ofox.io/anthropic/v1/models/anthropic/claude-sonnet-5.5
```

### 响应格式

返回单个 Model 对象，结构与列表接口中的对象一致。
