Image to video with Seedance 2.5
Generate a video from a first-frame image and a text prompt with
Seedance 2.5. Upload the first frame as image, and optionally a final
frame as end_image, using multipart/form-data.
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 request to generate a video from a first-frame image with Seedance 2.5. Upload the first frame as image using multipart/form-data.
The first-frame image to animate, in a common format such as JPEG, PNG, or WEBP, up to 50MB. Multipart requests only. The uploaded image is used for this request only and is not stored.
A natural-language prompt describing how the first frame should animate.
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}.
