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 with a request ID and a status URL to poll for the completed audio file (mp3 or wav), along with payment settlement details showing the amount of USDC charged via the x402 protocol.

Example use cases

Ambient background track for video

“Generate a 60-second calm lo-fi background music track suitable for a study video using stable-audio-2.5, and give it to me as an mp3.”

Sound effects for game development

“Create a 10-second dramatic thunderstorm sound effect with heavy rain and distant thunder using Stability AI's audio model — wav format please.”

Podcast intro jingle creation

“I need a short 15-second upbeat, energetic intro jingle for a tech podcast — generate it with stable-audio-2.5 as an mp3.”

When to prefer

Choose this endpoint when you need AI-generated audio from a text description and want to pay per-call with USDC via x402 without a subscription. It is especially suitable for agents that need on-demand audio generation in automated workflows, or when cost control via microtransactions is important. Prefer stable-audio-2.5 for higher quality at a fixed cost, or stable-audio-2 when step-level cost control is needed.

Side effects

Invalid model name returns an error — must be 'stable-audio-2.5' or 'stable-audio-2'
Duration exceeding model limits may fail or be clamped
Empty or missing prompt results in a generation error
Invalid output_format value (not 'mp3' or 'wav') causes a bad request
Payment failure via x402 if insufficient USDC balance
Long inference step counts on stable-audio-2 increase cost and latency significantly
Response is async — the data field may be empty until polled via statusUrl
