Text to video with Seedance 2.5
Generate a video from a text prompt with Seedance 2.5, at up to 1080p and
30 seconds. Returns a generation_id; poll GET /v2/generations/{generation_id}
or supply a webhook_url.
Authentication
API key for access control. Use in the header with the name "Api-Key"
Query parameters
When true, the request is validated and priced but not run: nothing is
generated, stored, or billed, and no safety review is performed. The
response is a PriceQuote object instead of the usual response for this
endpoint. Send exactly the request you would send to generate, so the
quote reflects the same options.
Request
A natural-language prompt describing the video to generate.
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.
The length of the generated video in seconds. When omitted, the model picks the best duration for the prompt ("auto").
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.
Response
An acknowledgement to poll with GET /v2/generations/{generation_id}.
The generation ID to poll with GET /v2/generations/{generation_id}.
