Example use cases
Game audio asset creation
“Create a 2-second sound effect of a sword clashing against a metal shield for my fantasy game, output it as a WAV file with full prompt adherence.”
Video production foley work
“Generate a realistic sound effect of a door creaking open slowly, about 1.5 seconds long, in MP3 format — I need it for a horror film scene.”
Ambient background audio loop

Endpoint
POSThttps://sol.blockrun.ai/api/v1/audio/sound-effects?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need programmatic, API-driven sound effect generation backed by ElevenLabs quality, especially within a Solana/x402 payment workflow. It is ideal when you want precise control over audio format (MP3, WAV, opus, PCM), clip duration, and prompt adherence. Prefer this over generic TTS endpoints when the goal is non-speech audio — environmental sounds, foley, game assets, or cinematic effects rather than voice synthesis.
Side effects
- Invalid or missing text description returns a 400 error
- Duration outside 0.5–22 second range may be rejected or clamped
- Unsupported response_format value returns a validation error
- Payment failure or insufficient USDC balance blocks the request
- Model ID not recognized returns an unknown model error
- Very vague prompts may produce generic or mismatched audio output
