Anthropic Messages

Anthropic 兼容接口，URL 路径 POST https://api.inflox.ai/v1/messages，适合 Claude Code 等 Anthropic 协议客户端。

该协议仅对启用了 anthropic 协议的模型可用。当前生产环境的模型默认仅启用 openai_chat 与 responses 协议，直接调用 /v1/messages 会返回 503 model_unavailable。需联系管理员在后台为模型启用 anthropic 协议后使用。


curl https://api.inflox.ai/v1/messages \
  -H "Authorization: Bearer wk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" \
  -H "Content-Type: application/json" \
  -H "anthropic-version: 2023-06-01" \
  -d '{
    "model": "{provider}/{model}",
    "max_tokens": 1024,
    "system": "You are a helpful assistant.",
    "messages": [{"role": "user", "content": "Hello"}]
  }'

非流式响应


{
  "id": "msg_...",
  "type": "message",
  "role": "assistant",
  "content": [{ "type": "text", "text": "Hello! How can I help?" }],
  "model": "{provider}/{model}",
  "stop_reason": "end_turn",
  "stop_sequence": null,
  "usage": { "input_tokens": 10, "output_tokens": 20 }
}

流式响应

通过请求体 "stream": true 触发，事件序列如下：


event: content_block_start
event: content_block_delta
event: message_delta
event: message_stop

错误响应

Anthropic 端点错误体与 OpenAI 不同：


{
  "type": "error",
  "error": { "type": "authentication_error", "message": "Invalid API key" }
}
