Sound Effects API - BudgetPixel API

Text → sound, video → synced effects. Foley, ambience, UI sounds, transitions and impacts from a short description, or a full effects track synced to what happens in a video. Each model has its own endpoint, POST /v1/audios/{model}.

Models

2 models. Each name opens its API reference with every parameter.

Model	Maker	What it does
Sonilo SFX `sonilo-sfx`	Sonilo	Foley, ambience, UI sounds, transitions, impacts and action effects from a short description, 1-180 seconds long.
Sonilo Video SFX `sonilo-video-sfx`	Sonilo	Frame-accurate Foley, ambience, impacts and action sounds synced to the visible events of an input video (up to 6 minutes).

How a request works

Send POST /v1/audios/{model} with a description or a video. The response returns a job id right away.
Poll GET /v1/audios/{job_id} until status is succeeded. The response then holds the sound’s URL; for a video, also the video with the effects mixed in.

Async jobs covers job statuses and errors.

Pricing

Sound effects are priced per second: of the length you ask for (3 seconds minimum), or of the video. GET /v1/models?type=audio returns current prices, and POST /v1/cost quotes a request before you send it. You pay only for jobs that succeed; see Pricing & credits.
