Technical details
Endpoint
POSThttps://agentservices.to/v1/audio/speechWhen to prefer
Choose this endpoint when your agent needs pay-per-call TTS without managing API keys or subscriptions — ideal for autonomous agents that need on-demand voice generation billed via x402 USDC micropayments on Base. Prefer it over direct OpenAI TTS when operating in a wallet-native, agentic micropayment context with no pre-registered credentials.
Side effects
- Empty or missing 'text' field returns a 400 validation error
- Invalid voice name (not one of alloy, echo, fable, onyx, nova, shimmer) may return an error or fall back to default
- Text too long may exceed model token limits and return a truncation or limit error
- Insufficient USDC balance or x402 payment failure results in 402 Payment Required
- Invalid model identifier may return a model-not-found error
