How this service works

Generative AI platform for images, 3D models, and audio — text-to-image, editing, upscaling, and more.

Output

Returns a JSON object containing a request ID and status URL for async retrieval of the transformed audio, along with payment settlement details confirming 0.001 USDC was charged. The actual audio data is accessible via the statusUrl once processing completes.

Example use cases

Music style transfer for producers

“I have a raw guitar loop — can you transform it to sound like a lo-fi hip-hop beat using Stability AI's audio-to-audio? Use stable-audio-2.5, 50 steps, strength 0.75, and output as mp3.”

Sound design for game audio

“Take this ambient forest recording and transform it into a dark, eerie dungeon soundscape using stable-audio-2 with 60 inference steps and a strength of 0.9, outputting as wav.”

Podcast music bed restyling

“I have a short music bed I recorded — can you restyle it to sound like an upbeat corporate background track using stable-audio-2.5, 50 steps, transformation strength 0.6, and output it as mp3?”

When to prefer

Choose this endpoint when you need to transform an existing audio file into a new style or character guided by a text prompt, rather than generating audio from scratch. It is ideal for music remixing, sound design restyling, and audio style transfer tasks. Prefer it over pure text-to-audio endpoints when you have a source audio file to anchor the generation. It is accessible via micropayment (0.001 USDC per call) with no subscription required, making it suitable for low-volume or ad-hoc agent workflows.

Side effects

Invalid or unsupported audio file format causes processing failure
Prompt too vague or empty may produce poor transformation results
Strength value out of 0–1 range triggers validation error
Unsupported model name causes a bad request error
Payment failure or insufficient USDC balance blocks the request
Request timeout if inference steps are very high
