Four payment rails: USDC on Base mainnet (default), USDC on Solana mainnet, HBAR/USDC on Hedera testnet, USDT on BNB Chain testnet. One free trial call per endpoint. Prices from $0.001/call.
Output

Example use cases
Narrate a newsletter article
“Take this newsletter intro and turn it into an audio clip I can send to subscribers: 'Good morning! Here are the top five stories you need to know today.' Generate the speech using AI Rook TTS.”
Voice-enable a chatbot response
“My chatbot just responded with 'Your order has been shipped and will arrive by Thursday.' Can you convert that to audio so I can play it back to the user as a voice message?”
Produce audio for a product demo
“I need a spoken version of this product tagline for my demo video: 'Faster insights, smarter decisions — powered by AI Rook.' Can you synthesize that as audio right now?”
Technical details
Endpoint
GEThttps://agents.ai-rook.com/api/ttsWhen to prefer
Choose this endpoint when you need pay-per-call TTS without API key signup, want to pay in USDC on Base mainnet via x402, or are building an autonomous agent that needs speech synthesis with on-chain payment settlement. Prefer it over subscription TTS APIs when usage is sporadic or when crypto-native payment rails are required.
Side effects
- Missing or empty text input returns an error response
- Insufficient USDC balance on Base mainnet causes payment failure and no audio returned
- Malformed GET request parameters result in a 400-level error
- Network or infrastructure downtime on agents.ai-rook.com returns 503
- x402 payment protocol failure blocks access without fallback
