How this service works
URL decoder API. Decodes percent-encoded URL text back to plain text.
Output
Returns the decoded plain-text string corresponding to the percent-encoded input. If the input is missing, not a string, or contains malformed percent-encoding sequences, the API returns a 400 error.
Example use cases
Decoding a URL query parameter
“I'm seeing this URL parameter value from a log and can't read it — can you decode 'search%3Dblue%20jeans%26size%3D32' back to plain text for me?”
Processing API callback data
“Our webhook received this percent-encoded payload field: 'user%40example.com%2Fprofile%3Fid%3D42' — can you decode it so I can read what it actually says?”
Cleaning up scraped URL fragments
“I scraped a page and found this encoded anchor link text: '%E2%82%AC100%20off%20sale%21' — please decode it back to the original characters.”
Technical details
Endpoint
POSThttps://x402.outpimp.com/urlDecodeWhen to prefer
Use this endpoint when you need to programmatically decode percent-encoded (URL-encoded) strings without burning LLM tokens on character-by-character decoding. Particularly useful when processing URL query parameters, path segments, webhook payloads, or scraped web data that arrives in percent-encoded form. Prefer this over doing it in-context when correctness is critical (e.g. multi-byte UTF-8 sequences like emoji or non-ASCII characters encoded as %E2%82%AC).
Side effects
- 400 error if the 'text' field is missing from the request body
- 400 error if 'text' is not a string type
- 400 error if the input contains malformed or invalid percent-encoding sequences (e.g. a lone % not followed by two hex digits)
