How this service works

200 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

Returns a JSON object with two fields: 'original' (the URL as provided) and 'normalized' (the canonical form with lowercased scheme and host, default port removed, dot-segments in the path resolved, and query parameters sorted alphabetically).

Example use cases

Deduplicating URLs in a crawler

“I have this URL HTTP://Example.COM:80/docs/../api/./v1?token=abc&lang=en and want to normalize it so I can compare it against already-visited URLs without false duplicates.”

Standardizing links before storage

“Before I save this URL to my database, can you normalize it — HTTP://MySite.ORG:80/blog/.././about?c=3&a=1 — so it's in a consistent canonical format?”

Cleaning redirect chains

“I collected this redirect destination URL from a web request — HTTPS://CDN.Example.Net:443/assets/../images/./logo.png?size=lg&fmt=webp — can you normalize it so I can compare it cleanly?”

Technical details

Endpoint

GEThttps://fastx402.tools/url-normalize?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need a lightweight, pay-per-call URL normalization step without setting up an account or API key — ideal for agents that occasionally need to canonicalize URLs as part of a larger workflow (e.g. deduplication, caching keys, link comparison) and want to pay only per use in USDC via x402 on Base or Solana.

Side effects

Missing required 'url' query parameter returns an error
Non-absolute or malformed URL may return an error or unexpected result
Payment failure via x402 protocol blocks the request
Network timeout if the FastX402 service is temporarily unavailable
