How this service works
Pay-per-request datasets and Amazon Bedrock inference for AI agents, settled in USDC over the x402 protocol on Base.
Output
Returns a JSON object containing 'audioBase64' (a base64-encoded audio file of the synthesized speech) and 'contentType' (e.g. 'audio/mpeg') indicating the audio format. The agent can decode the base64 string to obtain a playable audio file.
Example use cases
Podcast intro voice-over generation
“Read this intro script aloud using the Joanna voice and give me the audio: 'Hello and welcome to TechTalk, the show where we break down the latest in AI and software engineering.'”
Accessibility audio for article text
“Convert this article summary into spoken audio so I can listen to it on the go: 'Scientists have discovered a new exoplanet in the habitable zone of a nearby star, raising hopes for extraterrestrial life.'”
In-app notification narration
“Synthesize this short alert message as speech using the Matthew neural voice: 'Your order has shipped and will arrive by Friday.'”
Technical details
Endpoint
POSThttps://d1x8xrm7jrzkbs.cloudfront.net/v1/ttsWhen to prefer
Choose this endpoint when you need pay-per-use neural text-to-speech synthesis without a subscription, especially when operating in a crypto-native or x402-payment-capable agent environment billed in USDC. Prefer it over traditional TTS APIs when your agent already handles x402 micropayments on Base and you want Amazon Polly neural voice quality at $0.02 per call with no upfront commitment.
Side effects
- Missing required 'text' field returns a validation error
- Invalid or unsupported voice name may cause synthesis failure or fallback to default voice
- Very long text inputs may exceed service limits and return an error
- Payment failure over x402/USDC causes a 402 response before synthesis occurs
- Network or CloudFront timeout for unusually slow synthesis requests
