Anthropic Messages 接口字段

协议身份

  • 插件 ID：anthropic-messages。
  • Provider ID：claude-api。
  • 能力：text。
  • 默认 Base URL：https://api.anthropic.com。
  • 鉴权驱动：anthropic。
  • 创建：POST /v1/messages。
  • Agent：POST /v1/messages。
  • 生命周期：同步响应。

配置字段

字段 类型 必填 含义
apiKey secret 是 API Key

统一字段映射

统一字段 类型 必填 上游映射 说明
model string 是 model 上游模型 ID。
messages message[] 是 provider message container 包含历史消息和当前用户输入。
instructions string 否 system/instructions 系统指令。
temperature number 否 temperature 采样温度。
top_p number 否 top_p 核采样参数。
max_tokens integer 否 max_tokens/max_output_tokens 最大输出 token。
tools array 否 tools/toolConfig 工具定义。
tool_choice object string 否 tool_choice
response_format object 否 response_format/text 结构化输出配置。
stream boolean 否 stream 流式开关；后台任务当前以最终响应归一。

上游请求模板逐字段清单

下表由插件请求模板生成，覆盖 body、query、headers 和 multipart 文件声明中的每个字段。

Provider 扩展键

  • providerOptions.claude-api.anthropic-beta
  • providerOptions.claude-api.anthropic-version
  • providerOptions.claude-api.max_tokens
  • providerOptions.claude-api.metadata
  • providerOptions.claude-api.service_tier
  • providerOptions.claude-api.stop_sequences
  • providerOptions.claude-api.stream
  • providerOptions.claude-api.system
  • providerOptions.claude-api.temperature
  • providerOptions.claude-api.thinking
  • providerOptions.claude-api.tool_choice
  • providerOptions.claude-api.tools
  • providerOptions.claude-api.top_k
  • providerOptions.claude-api.top_p

动态模型或工作流允许使用文档声明的完整 parameters/input/extra_body 对象；该对象是协议本身的开放 schema，不会被宿主裁剪。

响应映射逐字段清单

映射位置 上游路径或转换表达式
response.status "succeeded"
response.text {"$map":{"from":{"$filter":{"from":{"$ref":"response.content"},"as":"part","where":{"$eq":[{"$ref":"part.type"},"text"]}}},"as":"part","in":{"$ref":"part.text"}}}
response.reasoning {"$map":{"from":{"$filter":{"from":{"$ref":"response.content"},"as":"part","where":{"$eq":[{"$ref":"part.type"},"thinking"]}}},"as":"part","in":{"$ref":"part.thinking"}}}
response.usage {"$ref":"response.usage"}
response.errorPaths[0] "error.type"
response.messagePaths[0] "error.message"
agentResponse.textPaths[0] "content.0.text"
agentResponse.reasoningPaths[0] "content.0.thinking"
agentResponse.toolCallsPath "content"
agentResponse.toolCallIdPaths[0] "id"
agentResponse.toolCallNamePaths[0] "name"
agentResponse.toolCallArgumentsPaths[0] "input"

响应与错误

插件把上游 task/status/text/media/usage 映射为统一结果。临时媒体 URL 标记为 ephemeral，由宿主立即下载持久化。HTTP 错误、业务 code 和 error object 保持失败语义，不包装成成功。

兼容边界

该包只代表上述线协议 profile；同一品牌的其他 endpoint、云区域或网关包装必须使用独立插件，不能根据模型名猜测。

Manifest 完整接口定义

以下 JSON 与插件包内实际 manifest.json 逐字段一致，覆盖插件身份、权限、配置、鉴权、参数、校验、创建、Agent、查询、取消、结果下载、响应和 Agent 响应映射。documentation 字段的值就是当前完整文档；为避免文档在自身内部无限递归，JSON 中仅用等义占位文本表示正文。
