InboxRhino

Documentation

InboxRhino is a receive-only test-email API. These pages are the public contract: how to create an inbox, wait for real mail, and clean up so quota is released. There is no send endpoint. Use the REST API directly; official SDK packaging is planned only after the API surface is stable.

  • API quickstart

    Create a key, provision a real inbox, wait for the message, delete the inbox. About five minutes.

  • API reference

    Authentication, quotas, wait-for-message, errors, OpenAPI, and the Postman collection.

  • Playwright email testing

    Assert signup, OTP and password-reset mail from Playwright without a plugin.

Developer resources: downloadable Postman collection · OpenAPI specification. Quotas and GST status are on InboxRhino pricing.
