Segmind Seedance alternative: the KreatorFlow API

1. Send the job to POST https://kreatorflow.ai/v1/videos instead of POST https://api.segmind.com/v2/seedance-2.0.
2. Authenticate with Authorization: Bearer $KREATORFLOW_API_KEY, a key from the developer console, instead of x-api-key: $SEGMIND_API_KEY.
3. Name the model in the body: "kreator-video-seedance-2" for Seedance 2.0, "kreator-video-seedance-2-5" for Seedance 2.5.
4. Keep the flat JSON body: prompt, resolution, duration, aspect_ratio and generate_audio keep their names.
5. Use a clip length of 4, 5, 6, 8, 10, 12 and 15 seconds.
6. Send generate_audio: true if you want audio: it is on by default there and off by default here.
7. Replace GET https://api.segmind.com/v2/requests/{id}/status, then GET https://api.segmind.com/v2/requests/{id} with webhook_url (signed with X-KreatorFlow-Signature) or GET /v1/jobs/{job_id}, and add an Idempotency-Key header so a retried request returns the same job.
