indox Developer Documentation

Welcome. This is the public documentation for the indox file-conversion platform.

If you are an external developer integrating with indox, you are in the right place.

What is indox

indox converts files — documents, images, audio, video, fonts — through a uniform REST API, spanning 6,022 conversions across the platform.

Conversions are asynchronous:

  1. POST /api/v1/<service>/convert/ → 202 with the conversion id
  2. Poll GET /api/v1/<service>/conversion/{id}/ → terminal state
  3. GET /api/v1/<service>/{id}/download/ → the file
