How this service works
Percent-decode text. Call when you reverse query encoding from agent-held URLs. Returns decoded text for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
A JSON object containing the decoded plain text string, with all percent-encoded sequences (e.g. %20, %2F, %3A) converted back to their original characters. No network calls are made; the operation is local and stateless.
Example use cases
Decode encoded query parameter value
“I extracted this query parameter from a URL and it's still percent-encoded: 'search%3Dcoffee%20shops%26location%3DNew%20York'. Can you decode it so I can read the actual values?”
Clean up logged URL fragments
“My logs are full of percent-encoded strings like '%2Fapi%2Fv1%2Fusers%3Fid%3D42' — can you decode that back to readable text so I can understand what paths were hit?”
Reverse encoding on scraped web data
“I scraped some text from a web page and it came back URL-encoded as 'caf%C3%A9%20menu%3A%20cr%C3%AApes%20%26%20espresso'. Please decode it to plain text.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/url-decode-safeWhen to prefer
Choose this endpoint when you need to safely reverse percent-encoding on a captured URL component, query parameter, or path segment — especially when robustness to malformed input matters. Prefer this over the sibling URL Encode endpoint when the direction is decode-only. Use when you want a stateless, no-retention, local decode with no side effects and a guaranteed sub-cent cost via x402.
Side effects
- Malformed percent sequences (e.g. truncated % escapes) may be passed through as-is or cause an error response
- Empty or null text input may return an error or empty result
- Input that is not actually percent-encoded will be returned unchanged
- Non-UTF-8 encoded sequences may not decode correctly
