How this service works
Machine-readable settlement service
Output
Returns an object containing the percent-encoded (URL-encoded) version of the input string, where special characters such as spaces, ampersands, slashes, and other reserved or unsafe characters are replaced with their %XX hex equivalents.
Example use cases
Encode query parameter value
“I need to URL-encode the text 'search query: cats & dogs (2024)' so I can safely append it to a URL as a query parameter — can you percent-encode it for me?”
Escape special characters in API request
“My API call keeps breaking because the value 'user@example.com/profile?tab=settings' has special characters — please URL-encode it so I can embed it in a URL safely.”
Prepare encoded URL segment for redirect
“I'm building a redirect URL and need to embed the path '/music/jazz & blues/top 10' as a safe encoded segment — can you percent-encode that string for me?”
