REST API

API Documentation

Integrate manga translation into your app with a simple REST API.

Quick Start

Get an API key

Create a key from your dashboard settings. Keys start with mg_live_ or mg_test_.

Upload an image

Request a presigned URL, then PUT the image bytes to it.

Create a job

Submit the upload key to start translation. Poll the job until it completes.

Authentication

Include your API key as a Bearer token in the Authorization header.

Authorization: Bearer mg_live_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Live mode keys (mg_live_) use your real credits.
Test mode keys (mg_test_) use mock GPU — no credits consumed.
