How this service works

Machine-readable settlement service

Output

A JSON object where each query parameter key maps to its corresponding value (or an array of values if a key appears multiple times), parsed from the input query string.

Example use cases

API request parameter extraction

“I have this query string from an incoming API request — 'product=widget&qty=5&discount=10&currency=USD' — can you turn it into a JSON object so I can work with the values?”

URL analytics parameter parsing

“Parse this tracking URL's query params into JSON for me: 'utm_source=newsletter&utm_medium=email&utm_campaign=spring_sale&utm_content=banner1'”

Form submission data parsing

“I got a form submission as a raw query string: 'first_name=John&last_name=Doe&email=john%40example.com&subscribe=true' — convert it to JSON so I can process it.”

Endpoint

When to prefer

Use this endpoint when you need a quick, paid micro-service to parse URL query strings into JSON without setting up server-side parsing logic. Ideal for agent workflows that receive raw URL query strings and need structured data, especially when operating in an x402 payment-enabled environment.

Side effects

Malformed or empty query string may return an empty object or error
URL-encoded characters that are improperly encoded may not decode correctly
Very long query strings may hit input size limits
Ambiguous repeated keys may produce inconsistent array vs. scalar handling
