OpenAPI Specification

openapi: 3.2.0
info:
  title: TwtAPI Backend Agent API
  description: API proxy & billing platform for Twitter/RapidAPI
  version: 0.1.0
tags:
- name: Agent
paths:
  /api/v1/agent/tools:
    get:
      summary: Tools
      description: '列出所有可用工具（需要 skill_key 鉴权）。


        返回:

        ``{"tools": [...]}``。注意响应体不是统一的 success() 包装，

        与 /invoke 保持一致的裸结构，这是 Agent 客户端的既有契约。


        副作用:

        无（只读内存中的工具目录），但仍受 AGENT_ENABLED 开关约束。'

  /api/v1/agent/invoke:
    post:
      summary: Invoke
      description: '执行一次 Agent 工具调用（需要 skill_key 鉴权，调用成功即扣费）。


        参数:

        body: tool（工具名）、params（工具参数）、session_id（可选，仅用于日志串联）。

        background_tasks: 用于在响应返回后异步写调用日志，不阻塞用户。


        返回:

        AgentInvokeResponse(code=200, tool, data, credits_used)。


        异常（均为 ApiException，由全局处理器转成统一错误体）:

        404 40420 功能未开启；404 40421 工具不存在；400 40021 必填参数缺失；

        403 40321 被风控拦截；429/503 限流相关（见 _check_limits）；
