## Usage notes

* Resolution is fixed to the case-sensitive schema value "2K". The prompt must contain non-whitespace text; the current provider serializer uses only its first 7,000 characters.
* Provide at least one image or video reference. Audio references require an image or video reference and cannot be used alone.
* Reference media may be cropped, resized, transcoded and trimmed. Video duration and audio duration are each normalized to fit within the provider's 15-second total budget.

## Quick start

Replace the example media URLs with publicly accessible URLs for your own files before submitting.

## Response

Submission returns a request handle. Poll `status_url` until `status` is `completed`, or use [webhooks](/docs/how-to/webhooks).

```json Accepted theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "status": "queued",
  "request_id": "REQUEST_ID",
  "status_url": "https://api.higgsfield.ai/requests/REQUEST_ID/status",
  "cancel_url": "https://api.higgsfield.ai/requests/REQUEST_ID/cancel"
}
```

A completed response includes the following output fields:

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "status": "completed",
  "request_id": "REQUEST_ID",
  "video": {
    "url": "https://example.com/output.mp4"
  }
}
```

See [polling](/docs/concepts/polling), [request errors](/docs/concepts/errors) and [authentication](/docs/authentication) for shared request handling.
