Endpoint
POSThttps://fish-audio.mpp.tempo.xyz/v1/audio/speech?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need high-quality AI-generated speech audio from Fish Audio's voice models, especially when operating in a crypto-native or agent payment environment that supports x402 one-shot USDC billing. It is ideal for agents that need to produce voiceovers, narrations, or spoken content on demand without managing a long-term subscription, and when you want access to Fish Audio's specific voice catalog and pricing transparency via the companion /v1/audio/models endpoint.
Side effects
- Invalid or unsupported voice model ID returns an error
- Text input too long for the selected model's character limit
- Insufficient USDC balance for the one-shot payment charge
- Malformed request body missing required text or model fields
- Unsupported audio output format requested
- Rate limiting if too many requests are made in quick succession
