How this service works
Browser rendering, transcription, image, vision, and speech on Cloudflare's edge.
Output
A binary audio file (spoken audio) containing the synthesized speech of the provided text, rendered in the selected voice and model quality.
Example use cases
Accessibility voiceover for web content
“Convert our entire blog post into an audio file using the shimmer voice so visually impaired users can listen instead of read. Use the highest quality model available.”
Customer support chatbot voice responses
“Turn these support replies into spoken audio messages using the onyx voice and tts-1 model so our agents can send voice notes back to customers quickly without typing.”
Multilingual product demo narration
“Generate audio narration for our product walkthrough video using the alloy voice and gpt-4o-mini-tts — I need the file to overlay on the video timeline.”
Technical details
Endpoint
POSThttps://cloudflare.payweave.services/tts/speakWhen to prefer
Choose this endpoint when you need pay-per-call TTS with no subscription, billed per 1k characters via USDC micropayment, running on Cloudflare's globally distributed edge for low-latency audio generation. Prefer it when you want OpenAI-compatible voice options (alloy, nova, shimmer, onyx, etc.) without managing an OpenAI API key directly, or when integrating into an x402-compatible payment flow.
Side effects
- Text exceeds 2000 character limit — request rejected or truncated
- Invalid model name supplied — falls back to default or returns error
- Invalid voice name supplied — may return error or use default voice
- Payment not accepted or USDC balance insufficient — 402 response blocking the call
- Empty text field — likely returns 400 bad request
- Service unavailable on Cloudflare edge — 503 or timeout
