How this service works
Parse or build URL query strings for $0.002 USDC for $0.002 USDC. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.
Output
Returns either a structured key-value object representing parsed query parameters, or a properly encoded query string built from the provided input parameters, depending on the operation requested.
Example use cases
Extract UTM parameters from campaign URL
“I have this URL query string from a campaign link — 'utm_source=google&utm_medium=cpc&utm_campaign=launch&utm_content=banner' — can you parse it out into separate key-value pairs so I can log them?”
Build query string for API request
“I need to build a URL query string from these parameters: search term is 'blue sneakers', page is 2, sort is 'price_asc', and max_price is 150. Can you encode that into a proper query string?”
Decode percent-encoded URL parameters
“This query string has weird percent-encoded characters in it — 'q=hello%20world&tag=caf%C3%A9&redirect=%2Fhome' — can you decode it into readable key-value pairs?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/query-string?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call utility to parse or construct URL query strings without running your own parsing logic. Ideal for agents that frequently handle URLs, form submissions, or HTTP request building and want a reliable hosted utility at low cost ($0.001 USDC).
Side effects
- Malformed input query string may return a parsing error or partial result
- Invalid characters or encoding may cause encode/decode failures
- Missing required operation type (parse vs. build) may result in a 400 error
- Empty input string may return an empty result or error
