service_not_found — no such service

422 with reason: "service_not_found" and without errors: the request passed shape validation but failed at service resolution. The order was not created.

The most common cause is a task_type that cannot be created publicly. The values image, txt2img, remix, image_edit, voice_clone are in the enum, so they pass request validation — but no service with that code exists in the public API. Only tts, sfx, music, and voice_search can be created with an API key; the other enum values exist solely for the GET /orders?task_type[]=… filter. The second cause: the service exists but is not active.

Check against the list of creatable types and do not send the rest. The same reason appears on GET /usage/{service} as a 404: there, service is the service_code from GET /usage, not an arbitrary string.

POST /orders with a task_type from the four supported ones or with a template_id (for TTS a template is required: the voice is set by config.tts_settings.voice_id of the template, and there is no orders.voice_id field). Which config keys the service accepts — GET /templates/config-options?service=<code>.
