How this service works
Machine-payable x402 utilities for hashing, Base64, UUID generation, unit and timezone conversion, realtime crypto market data, webpage/document extraction, URL-to-Markdown, metadata, RAG ingestion and deterministic website change detection.
Output
Returns a JSON object indicating the parsed key-value pairs from the query string (when in parse mode) or a fully encoded query string (when in build mode), with a status field confirming readiness.
Example use cases
Decode URL parameters from API response
“I got a redirect URL back from an OAuth flow with a bunch of parameters in the query string — can you parse '?code=abc123&state=xyz&session_id=9876' into separate fields so I can extract the auth code?”
Build query string for API request
“I need to build a properly encoded query string from these parameters: search='blue shoes', size=10, page=2, sort='price_asc' — put it together for me so I can append it to an API URL.”
Convert form data to URL-encoded format
“Take these form fields — name='John Doe', email='john@example.com', subscribe=true — and encode them as a URL query string I can use in a GET request.”
Technical details
Endpoint
POSThttps://x402-gateway-production-1f21.up.railway.app/querystring?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call utility to parse or build URL query strings without spinning up your own encoding logic, especially in agent workflows operating over the x402 micropayment protocol where per-call billing is acceptable at $0.001 USDC.
Side effects
- Missing required 'input' field returns a validation error
- Invalid mode value (not 'parse' or 'build') causes rejection
- Malformed query string input may result in incomplete parsing
- Incorrect bodyType specification may cause body parsing failure
- Payment failure via x402 protocol blocks the request entirely
