OpenAPI Specification

openapi: 3.2.0
info:
  title: Hypamoon Messages API
  version: 1.0.0
  description: 'Hypamoon is the infrastructure a chat or an agent builds on for a business: sites and apps (with server code, sign-in and their own database), data and forms, a media library, domains, email from your own domain, phone numbers with voice AI, SMS and chat, payments (see https://hypamoon.com/docs/payments) and agents. The same project is reachable from a connected chat over MCP and from your own code over this REST API.


    Calls are inbound, plus outbound calls your assistant makes to people who expect them (POST /calls).


    Every request needs an API key: `Authorization: Bearer hm_live_...`, or `hm_test_...` in test mode. Each key has scopes and a rate limit of 120 requests per 60 seconds.


    An OAuth access token (`hm_oat_...`, from connecting an assistant such as Claude.ai or ChatGPT) works on every /api/v1 route as well, with the scopes the user granted on the consent screen. For your own app, create an API key in the portal instead.


    Every error is `application/problem+json` with a `type` URL that explains the fix (`https://hypamoon.com/docs/errors/`). Every response carries an `X-Request-Id` header; include it when you ask us for help.


    Field names are snake_case, except inside a call plan, which is stored exactly as you send it (camelCase). New fields may be added to a response at any time; renaming or removing one requires a new version.'
