How this service works

Machine-readable settlement service

Output

A JSON object containing the percent-encoded version of the input string, where all characters except A–Z, a–z, 0–9, -, _, ., and ~ are replaced with their %XX UTF-8 hex escape sequences, matching JavaScript's encodeURIComponent output.

Example use cases

Encoding search query for URL

“I need to embed this search phrase into a URL query string — can you percent-encode 'coffee shops near me & open now' so it's URL safe?”

Escaping user input for API call

“A user typed 'name=John Doe&age=30' into a form field and I need to pass it as a single query param value — please URL-encode it for me.”

Encoding file path for REST endpoint

“I have a file path '/reports/2024/Q1 summary (final).pdf' that I need to embed in a URL segment — can you encodeURIComponent it for me?”

When to prefer

Choose this endpoint when you need reliable, standards-compliant encodeURIComponent-style percent-encoding as a paid micro-service, particularly within x402 payment-enabled agent workflows where you want a simple, composable utility that handles encoding without running your own server-side code.

Side effects

Missing 'input' field in request body returns a validation error
Payment failure or insufficient USDC balance prevents the call from executing
Non-string input type may cause unexpected encoding or rejection
Empty string input returns an empty string result without error
Very long strings may hit payload size limits
