info:
  title: Call2Me API Keys API
  description: '# Call2Me Voice AI Platform API


    Programmatic interface to build, deploy and operate voice AI agents that can place

    and receive phone calls in real time. Designed to be consumed by humans **and** by

    AI agent frameworks (function-calling LLMs, MCP servers, automation platforms like

    Composio, Pipedream, Zapier, n8n).


    ## What you can do


    - **Place outbound calls** — give an agent a phone number to dial; the AI handles

    the conversation end-to-end and returns a transcript + recording.

    - **Manage AI agents** — create personalities, attach voices, system prompts,

    knowledge bases and post-call actions.

    - **Schedule calls** — one-shot or recurring (cron-like) outbound calls.

    - **Knowledge base (RAG)** — upload documents/URLs so the agent answers from your

    data with reduced hallucination.

    - **Inbound** — provision phone numbers that route to your agents.


    ## Common LLM tool-calling use cases


    | Goal | Endpoint |

    |------|----------|

    | "Call this person and read them this script" | `POST /v1/calls` |

    | "Schedule a follow-up tomorrow at 14:00" | `POST /v1/schedules` |

    | "Get the transcript of last call" | `GET /v1/calls/{id}` |

    | "Add this PDF to the agent''s brain" | `POST /v1/knowledge-base/{id}/sources` |


    ## Authentication


    Every request requires a Bearer token issued from the dashboard:


    ```

    Authorization: Bearer c2m_sk_xxxxxxxxxxxxxxxx

    ```


    Get your API key from the API Keys page.

    Keys are scoped per-workspace and can be rotated/revoked any time.


    ## Rate Limits


    | Plan | Requests/min | Concurrent Calls |

    |------|-------------|------------------|

    | Free | 60 | 1 |

    | Pro | 600 | 10 |

    | Enterprise | Unlimited | Unlimited |


    ## SDKs & Integrations


    - Python SDK

    - Node.js SDK

    - OpenAPI 3.1 spec: `/openapi.json` (use it to generate clients or register the

    service with AI tool platforms)
