How this service works
Percent-encode and decode a string for URLs — Genesis402 / UnyKorn Operator Network
Output
A JSON object with an 'ok' boolean, the transformation type ('encode-url'), the encoded or decoded result string, and a payment receipt containing the transaction hash, USD amount charged, and a unique receipt ID.
Example use cases
Encode query parameter with special characters
“I need to put the text 'price >= $50 & category=shoes' into a URL query string — can you percent-encode it so the browser doesn't break it?”
Decode a percent-encoded URL fragment
“I've got this URL fragment that looks garbled with percent signs — can you decode '%E2%82%AC29%20sale%20%2650%25%20off' back into readable text?”
Sanitize user input for URL path
“A user submitted the name 'Björk / The Artist' and I need to put it in a URL path segment — please percent-encode it so it's URL-safe.”
Technical details
Endpoint
POSThttps://twin.unykorn.org/encode-url?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pay-per-call, serverless percent-encoding or decoding operation with a blockchain payment receipt for auditability — particularly useful in agentic pipelines on the x402 network where on-chain receipts are required. For high-volume or free encoding needs, a local library function may be preferable; this endpoint is best when you need provable, receipted execution or are already operating within the UnyKorn/x402 ecosystem.
Side effects
- Text input exceeds 49,152 character limit — request rejected
- Malformed or missing 'text' field in params — validation error
- Payment failure via x402 protocol — 402 response, no result returned
- Network timeout reaching twin.unykorn.org — connection error
