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-2", "prompt": "a cute robot mascot, flat vector logo" }'
# → { "id": "cmus7q0x9000108l3f5g2abcd", "status": "queued" }#Request parameters

#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).
