聊天接口

POST/claude/v1/messages

这里只列出部分常用参数，完整参数说明参考 Claude 官方文档：https://docs.anthropic.com/claude/reference/messages_post

模型定价均为官方定价的 1.5 倍。

支持用同样的方式设置和使用 API2D 提供的【搜索】、【知识库】、【联网】功能。

Claude 入口已经兼容 OpenAI 应用，直接在 OpenAI 应用中使用地址 https://oa.api2d.net/claude 即可使用 Claude。所有 GPT-3 模型会被映射为 claude-3-5-sonnet-20240620，所有 GPT-4 模型会被映射为 claude-3-opus-20240229。

请求参数

Header Params

x-api-key

string

required

x-api-key和Authorization作用相同，选一个使用即可。x-api-key主要是为了兼容Claude的参数格式。

Example:

fk186009-...

model

enum<string>

required

Allowed values:

claude-3-opus-20240229claude-3-sonnet-20240229claude-3-haiku-20240307claude-2.1claude-2.0claude-instant-1.2

messages

array [object {2}]

required

<= 1 items

role

string

required

content

string

required

stream

boolean

optional

是否启用流式返回

Default:

false

max_tokens

integer

optional

如果不指定，每次请求会预先冻结模型支持的最大生成 Token（目前是 4096），在请求完成后按 usage 字段多退少补。如果账户余额不够冻结就会报错，此时可以指定一个比较小的 max_tokens，这样就会按 max_tokens 来冻结
