## OpenAPI

````yaml https://api.meowmail.in/api/v1/openapi.json get /api/v1/domains
openapi: 3.1.0
info:
  title: MeowMail API
  version: 1.0.0
  summary: Free disposable email API. Receive-only, no accounts, TTL-expiring inboxes.
  description: >-
    Create throwaway inboxes and read the mail they receive.


    Built for automated testing of signup and verification flows, and for
    privacy tooling.


    **Inboxes are public.** There is no authorization on inbox contents: anyone
    who knows the address can read it. Never use MeowMail for anything you would
    mind a stranger reading, and never for password resets on accounts that
    matter.


    **Mail is ephemeral.** Emails are permanently deleted roughly one hour after
    arrival.


    **Receive-only.** There is no send endpoint and never will be in this API
    version.
