The order was not created. ## Why 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. ## What to do 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. ## Next request `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=`. ## Related - [Guide: order types and statuses](https://lumean.app/en/developers/docs/guide/async) - [Guide: templates](https://lumean.app/en/developers/docs/guide/templates) - [POST /orders](https://lumean.app/en/developers/docs/api/post-orders) - [GET /templates/config-options](https://lumean.app/en/developers/docs/api/get-templates-config-options) - [422 — request not accepted](https://lumean.app/en/developers/docs/errors/422) --- - This page in the browser: https://lumean.app/en/developers/docs/errors/service-not-found - Full machine-readable reference: https://api.lumean.app/docs/llm.md
