How this service works
Machine-readable settlement service
Output
Returns an object containing the decoded string result — the percent-encoded input converted back to its original plain-text representation, with all escape sequences like %20, %3D, %26, etc. resolved to their corresponding characters.
Example use cases
Decode query parameter from web log
“I pulled this query string from our server logs and it's percent-encoded — can you decode 'search%3Dlaptop%26brand%3DApple%26price%3C%3D1000' so I can read it properly?”
Unescape encoded redirect URL
“I have this redirect URL that came back encoded: 'https%3A%2F%2Fexample.com%2Fpath%3Ffoo%3Dbar' — can you decode it into a normal readable URL?”
Parse encoded form submission value
“A form submission came in with the email field set to 'john.doe%40example.com%2Btest' — please decode that so I can extract the actual email address.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/encoding.url-decode--decode-uri-componentWhen to prefer
Use this endpoint when you need a quick, pay-per-call decodeURIComponent operation without setting up a local runtime — ideal for AI agents, serverless pipelines, or no-code workflows that receive percent-encoded strings from web requests, logs, or APIs and need them decoded on the fly.
Side effects
- Malformed percent-encoding (e.g. incomplete escape like %2) may result in an error or partial decode
- Input that is already plain text with no encoding may pass through unchanged
- Very long input strings may hit payload size limits
- Invalid UTF-8 sequences in encoded input may cause decoding errors
