## Parameters

- `resolution`: "480p", "720p", "1080p", "4K" (default "720p")
- `duration` (seconds): 4, 5, 8, 10, 15 (default 8)

- `count`: 1, 2 or 4 takes per run
- `references`: 9 reference images, 3 reference videos, 3 audio tracks, a first frame, a last frame. Each item is `{ "asset_id" | "url" | "take_id" | "element_id", "role": "reference" | "first_frame" | "last_frame" }`.
- `project_id`: the project the cost lands on (defaults to the key's project, then the newest one).
- `webhook_url`, `metadata`: optional.
- `tags`: up to 10 labels for usage reports, e.g. `{ "client": "acme", "campaign": "q4" }` (or header `X-Takes-Tags: client=acme,campaign=q4`).

Unsupported values return HTTP 400 with `param` and `supported` in the error, so you can correct and resend.

## Call it

```bash
curl -X POST https://edengen.ai/v1/takes \
  -H "Authorization: Bearer $TAKES_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Prefer: wait=60" \
  -d '{"model":"seedance-2.0","prompt":"Slow dolly in on a rain-soaked neon street at night, handheld feel, no music, no cut","resolution":"720p","duration":8,"aspect_ratio":"16:9"}'
```

Check the price first with `POST https://edengen.ai/v1/estimate` (same body). Poll `GET https://edengen.ai/v1/takes/{id}` or pass `webhook_url`.
Never resend a create to check progress: a new request is a new paid take unless it carries the same Idempotency-Key.
