Wan - 2.2 A14B Speech to Video Turbo

Endpoint

POST /audio/generations

Full URL: https://modelfold.ai/v1/audio/generations

Authentication: every request must include the Authorization: Bearer <API_KEY> header.

Send model parameters directly in the JSON body. Do not wrap them in input. This request waits for generation to finish and returns data[].url; supported media models also offer async jobs, polling and callbacks. Replace example media URLs with your own publicly accessible files. See API gateway for billing and errors.
