How this service works
AI rewrite of input text

Example use cases
Polishing a product description
“Take this rough product blurb and rewrite it so it sounds more compelling and professional: 'this gadget is cool and it charges your phone fast and everyone loves it'.”
Improving a customer email draft
“Rewrite this draft email to a client so it sounds cleaner and more formal: 'hey just wanted to check if you got our invoice we sent it last week and need payment soon thanks'.”
Enhancing social media copy
“Make this social media post sound more engaging and natural: 'we have a new thing launching soon it is going to be great please follow us for updates'.”
Technical details
Endpoint
POSThttps://www.api-xpay.com/x402/rewrite?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, pay-per-use text rewriting without a subscription, especially in autonomous agent workflows that already handle x402/USDC micropayments on Base. Ideal when you want to avoid API key management and pay only for what you use.
Side effects
- Payment not received or insufficient USDC balance — 402 error returned
- Missing required fields (type, method, bodyType, body) — validation error
- Invalid bodyType enum value — request rejected
- Empty or malformed body object — unclear rewrite output
- Network congestion on Base causing payment settlement delay
