How this service works
Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.
Output
Returns rewritten or voice-optimized text content derived from the input. Unpaid requests (missing or invalid EIP-3009 payment authorization) return HTTP 402 with payment challenge details specifying the required $0.02 USDC amount and EIP-3009 payment extras for the OpenX402 facilitator.
Example use cases
Podcast script voice optimization
“Take this blog post section and rewrite it so it flows naturally as spoken audio for my podcast — remove the jargon and make it conversational: 'Blockchain interoperability remains a core challenge for DeFi protocols seeking cross-chain liquidity.'”
Voice assistant response rewriting
“Rewrite this customer support answer so it sounds good when a voice assistant reads it out loud — no bullet points, no abbreviations, keep it under 30 seconds of speech: 'Your order #4821 has shipped via FedEx, tracking number 794644792798, expected delivery Friday.'”
Ad copy spoken-word adaptation
“I have ad copy written for print that I need adapted for a radio spot — can you rewrite it to sound natural and engaging when spoken? The original is: 'Save 40% on premium memberships. Limited time. Visit us at app.example.com.'”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/voicerewrite?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to rewrite text content specifically for voice/spoken delivery and are operating within an x402 micropayment-enabled agent stack using USDC. It is best suited for agents that already handle EIP-3009 payment flows via the OpenX402 facilitator and need per-call, low-cost voice content transformation at $0.02 per request without subscription overhead.
Side effects
- HTTP 402 returned if no valid EIP-3009 payment token is provided — response includes payment challenge with USDC amount and facilitator info
- Invalid HTTP method returns error (only GET, HEAD, DELETE, POST accepted)
- Missing required 'input' object or 'method' field returns validation error
- OpenX402 facilitator unavailable may cause payment verification failure
- Malformed query parameters or body may result in processing error
