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": "nano-banana-pro", "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 image to generate (max 20000 chars).
`image_input`	string[]	No	—	Optional reference/source image URLs to transform (max 8, ≤30MB each; jpeg/png/webp).
`aspect_ratio`	string	No	`1:1`	Aspect ratio of the output image. Options: 1:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9, auto
`resolution`	string	No	`1K`	Output resolution. Higher resolutions take longer to generate. Options: 1K, 2K, 4K
`output_format`	string	No	`png`	Format of the output image. Options: png, jpg
`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")
