Execution Flow

Asynchronous submission model. Submitting requests queues background workers.

#Submit a task

Media generation is asynchronous: you get a task id immediately, without waiting.

bash

curl https://api.sozdai.ai/v1/media/generations \
  -H "Authorization: Bearer $CORRY_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "model": "seedance-2-image-to-video", "prompt": "a cute robot mascot, flat vector logo" }'
# → { "id": "cmus7q0x9000108l3f5g2abcd", "status": "queued" }

#Request parameters

Parameter	Type	Required	Default	Description
`prompt`	string	Yes	—	Text prompt describing the video (3–20000 chars).
`first_frame_url`	string	No	—	First-frame image (URL or asset://id).
`last_frame_url`	string	No	—	Last-frame image; pair with first_frame_url for first&last-frame mode.
`resolution`	string	No	`720p`	Video resolution. Higher resolution costs more: 720p ≈ 2×, 1080p ≈ 5× of 480p — see the pricing page. (4K not supported.) Options: 480p, 720p, 1080p
`aspect_ratio`	string	No	`16:9`	Aspect ratio. Options: 1:1, 4:3, 3:4, 16:9, 9:16, 21:9, adaptive
`duration`	number	No	`5`	Video length in seconds (4–15). Billed per second × resolution.
`generate_audio`	boolean	No	`true`	Generate an audio track (default on).
`web_search`	boolean	No	—	Use online search to enrich generation.
`nsfw_checker`	boolean	No	`false`	Content filter; false disables filtering.
`callback_url`	string	No	—	Optional public http(s) URL. We POST the task result here the moment generation finishes (success or failure).

#Poll for the result

Generation runs asynchronously — the submit call returns immediately with a task id. Poll this endpoint with that id every few seconds until status becomes succeeded (result ready) or a terminal error (failed / timeout).

GEThttps://api.sozdai.ai/v1/media/generations/{id}

bash

# take the id from the submit response, then poll every ~3s
curl https://api.sozdai.ai/v1/media/generations/cmus7q0x9000108l3f5g2abcd \
  -H "Authorization: Bearer $CORRY_KEY"
# repeat until "status" is "succeeded" (or "failed" / "timeout")
