# Generate a video from a text prompt with Seedance 2.0

`POST /v2/video/generate/seedance-2-text-to-video`

Generate one or more videos from a text prompt with Seedance 2.0.

Video generation always runs asynchronously: the response returns as
soon as the request is accepted and carries only a `generation_id`.
Poll for completion and results with
`GET /v1/generations/{generation_id}` using that id, or supply a
`webhook_url` to have the finished result POSTed to your server
instead.

Video links are available for a limited period of time; download the
video if you want to keep it.

## Query parameters

- `dry_run` boolean

## Request body

- GenerateVideoSeedDance2TextToVideoRequest — Request body for Seedance 2.0 text-to-video generation.
  - `prompt` string, required — A natural-language prompt describing the video to generate.
  - `aspect_ratio` 'auto' | '21x9' | '16x9' | '4x3' | '1x1' | '3x4' | '9x16' — The aspect ratio of the generated video. `AUTO` lets the model choose the most suitable ratio from the prompt; any other value pins the ratio.
  - `resolution` '480p' | '720p' — The resolution tier of the generated video.
  - `duration` integer — The length of the generated video in seconds. When omitted, the model picks the best duration for the prompt ("auto").
  - `generate_audio` boolean — Whether to generate an audio track for the video. Audio roughly doubles the provider cost and is subject to stricter output moderation.
  - `webhook_url` string, uri — HTTPS URL that Ideogram delivers the generated result to. Ideogram sends a JSON POST to this URL once all images for the request have finished generating. The body mirrors the synchronous generate response: `request_id`, `created`, and a `data` array containing every generated image (`url`, `prompt`, `resolution`, `seed`, `is_image_safe`). Each delivery is signed with Ed25519 and verifiable against the public keys at `https://api.ideogram.ai/v1/.well-known/jwks.json`. Must be HTTPS; private and loopback hosts and the cloud metadata service are rejected.
  - `private` boolean, nullable — When true or omitted, the output is kept private to your account. Set to false to publish the output to the public feed. Enterprise accounts always generate privately.
  - `target_collection_id` string — A collection you can write to, by its URL-safe base64 collection id. The output videos are added to it when the request completes.

## Response `200`

An acknowledgement to poll with `GET /v1/generations/{generation_id}`.

- GenerateVideoSeedDance2Response — Acknowledgement returned by the Seedance 2.0 video endpoints. Video generation always runs asynchronously, so the generated videos are never part of this response: poll for them with `GET /v1/generations/{generation_id}` using the returned `generation_id`, or receive them at the `webhook_url` you supplied.
  - `generation_id` string, required — URL-safe base64 ID of the accepted generation. Accepted by the `GET /v1/generations/{generation_id}` polling endpoint.
  - `created` string, date-time, required — The time the request was accepted.

## Other responses

- `400` — Invalid input provided.
- `401` — Unauthorized.
- `402` — Insufficient credits or quota.
- `403` — This account does not have access to this model.
- `422` — The prompt did not pass safety checks.
- `429` — Too many requests.
- `500` — Internal server error.
- `503` — The endpoint is temporarily unavailable.
