How this service works
Machine-readable settlement service
Output
Returns a JSON object containing an 'operation' field describing the transformation performed and a 'result' field with the parsed key-value pairs from the query string as a structured JSON object. Additional fields may be present.
Example use cases
Parse analytics tracking parameters
“I have this URL query string from our analytics link: 'utm_source=newsletter&utm_medium=email&utm_campaign=spring2024&utm_content=header' — can you convert it into a JSON object so I can read the values cleanly?”
Extract form submission data
“I got a form POST encoded as a query string: 'firstName=John&lastName=Doe&email=john%40example.com&subscribe=true' — can you parse that into structured JSON for me?”
Decode API redirect parameters
“After an OAuth redirect I have this query string: 'code=abc123&state=xyz789&scope=read+write' — please convert it to JSON so I can extract the auth code.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/f/url.query-to-jsonWhen to prefer
Choose this endpoint when you need a quick, cheap ($0.001 USDC) micro-service to programmatically parse a URL query string into JSON without standing up your own parsing logic. Ideal for agent pipelines that receive redirect URLs, form submissions, or analytics links and need structured access to the parameters.
Side effects
- Malformed or empty query string may yield an empty result object or error
- URL-encoded special characters that fail decoding may be omitted or cause parsing errors
- Very long query strings may be truncated
- Non-standard query string formats (e.g., nested brackets) may not parse as expected
- Payment failure (402) if USDC balance is insufficient
