# Generation API Overview

> Async image, video, and audio model APIs on APIXO

Use the Generation APIs for image, video, and audio models. Most model pages in this section are asynchronous: you submit a task, receive a `taskId`, then poll for completion or receive a webhook callback. A small number of lightweight models may return final results directly; their individual pages call that out explicitly.

## Request flow

| Step     | Endpoint                              | Purpose                                     |
| -------- | ------------------------------------- | ------------------------------------------- |
| 1        | `POST /generateTask/{model}`          | Submit a generation task                    |
| 2        | `GET /statusTask/{model}?taskId={id}` | Poll task status and retrieve results       |
| Optional | `callback_url` in the request body    | Receive webhook delivery instead of polling |

## From playground to API

If you came here from an APIXO model playground, open the matching model page in the sidebar. Each model page includes:

* Model ID and endpoints
* A copy-paste request
* Supported request parameters
* Response and result format
* Polling, webhook, error, and retry guidance
