How this service works

Rent trusted AI models priced per token; lend idle subscriptions and API keys. A live, metered market that settles every call in USDC on Solana.

Output

The response body is raw audio bytes in the requested format (default: audio/mpeg). The Content-Type header reflects the provider's audio type. For SSE stream_format, audio is framed as server-sent events. No JSON wrapper — just the binary audio data ready to play or save.

Example use cases

Podcast intro narration generation

“Turn this intro script into spoken audio using elevenlabs/eleven_multilingual_v2 with the 'Adam' voice and return it as an mp3: 'Hello and welcome back to TechTalk, the podcast where we break down what's happening in the world of technology.'”

Multilingual e-learning voiceover

“I need an audio narration for an online course slide — use elevenlabs/eleven_multilingual_v2, voice 'Bella', and produce a flac file from this text: 'In this module, you will learn the fundamentals of machine learning and how neural networks process data.'”

Accessibility audio for article

“Read this news article excerpt aloud using the ElevenLabs eleven_multilingual_v2 model and the 'Josh' voice, output as wav: 'Scientists announced today a major breakthrough in quantum computing that could change the landscape of data encryption.'”

Technical details

Endpoint

POSThttps://api.aile.sh/v1/audio/speech?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need access to premium third-party speech synthesis models (such as ElevenLabs) without managing individual provider subscriptions, and when you want pay-per-use USDC micropayment billing per 1,000 characters. Ideal for agents that need flexible, multi-provider TTS access through a single API surface with crypto-native settlement on Solana.

Side effects

Invalid or unsupported model string — returns error if model is not listed in GET /v1/models?output_modalities=speech
Voice ID not found for the selected provider — returns provider error
Insufficient USDC balance to cover the per-1000-character charge — payment rejected
Input text too long or empty — validation error
Unsupported response_format for the chosen model — format mismatch error
SSE streaming requested but audio streaming requires an API key — returns auth error
