## Parameters

Send these fields in a flat JSON body. Add `_run` to choose execution options.

Provide at least one of: url; video_url.

- **`url` string Optional**
  Regular YouTube video URL, youtu.be URL, shorts URL, or video ID for the video to convert. Preferred name; video_url remains supported.

### Advanced & compatibility inputs 1

- **`video_url` string Optional**
  Regular YouTube video URL, youtu.be URL, shorts URL, or video ID for the video to convert. You can also use url.

## Response

Every response describes a run. Read `result` once `run_status` is `succeeded`.

- **`run_id`**
  The run to track. Keep it when contacting support.

- **`run_status`**
  Queued, running, waiting for sign-in, succeeded, or failed. Check this even after an HTTP 200.

- **`status_url`**
  Poll this URL while the run is pending. Keep the same run instead of starting another request.

- **`result`**
  The endpoint’s returned data. The example is illustrative; actual fields may be empty or unavailable.

- **`error`**
  On failure, inspect its code, message, retryable and action fields.

## Errors & retries

- `400` Fix the fields listed in `errors` before retrying.

- `428` Connect the requested website account using the returned sign-in link.

- `429` Wait for the duration in `Retry-After`.

- `5xx` Retry transient failures with backoff. Keep the request ID.

A failed run has its own error inside the response. Retry it only when `error.retryable` is true.

Requests can return before a run finishes. Check run_status and poll status_url when needed.
