How this service works
146 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.
Output
A JSON object containing: href (fully normalized URL), protocol, origin, hostname (ASCII/punycode), hostname_unicode (human-readable Unicode form), port (null if default), path, query (object mapping parameter names to arrays or string values, with percent-encoding decoded), fragment (anchor text), and is_ip (boolean indicating if the host is an IP address).
Example use cases
Normalize links before deduplication
“I have this URL from a scraper: 'HTTP://Example.COM/Search?q=hello%20world&lang=en#results' — can you normalize it with WHATWG parsing and show me the cleaned href, hostname, path, and all query parameters decoded?”
Decode internationalized domain name
“This link has a weird punycode hostname: https://xn--bcher-kva.example.de/catalog — what does the Unicode hostname actually say, and what's the path?”
Extract query parameters for analytics
“Pull apart this tracking URL for me: https://shop.example.com/product?utm_source=email&utm_campaign=summer&id=42&ref=home — I need each query parameter listed separately so I can log them.”
Technical details
Endpoint
GEThttps://fastx402.tools/url-inspect?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need WHATWG-compliant URL parsing that matches browser behavior exactly, especially for internationalized domain names (IDN/punycode), multi-value query parameters, or percent-encoded characters. Prefer it over custom regex parsing when normalization consistency and standards compliance matter, or when you need both ASCII and Unicode hostname representations.
Side effects
- Malformed or relative URL input returns an error — only absolute URLs with a scheme are accepted
- Missing required 'url' query parameter results in a validation error
- Non-HTTP/HTTPS schemes may parse differently or fail depending on WHATWG support
- Extremely long URLs may be rejected or truncated
