# URL Parser (WHATWG)

> URL Parser (WHATWG) is a paid API for AI agents from url.openverbs.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Parses an absolute URL string into its WHATWG-standard components including protocol, credentials, host, port, origin, pathname, path segments, query object, and hash.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability url-parser-whatwg-830bf9ad -d '<json body>'
```

Example prompt: Can you parse this URL for me — 'https://user:pass@api.example.com:8080/v2/items?filter=active&page=2#results' — and give me all its components like the protocol, host, port, pathname, query parameters, and hash?

## When to prefer this

Use this endpoint when you need a reliable, standards-compliant (WHATWG) decomposition of a URL into all its named components in a single call — especially when you need the query string decoded into a structured key-value object and path segments as an array. Prefer it over regex-based parsing or manual string splitting when correctness and spec compliance matter.

## Known failure modes

- Non-absolute URLs (relative paths, protocol-relative) rejected with 400
- Malformed URLs with invalid characters return 400
- Empty or missing 'url' field returns 400 validation error
- URLs exceeding 8192 characters rejected
- Non-string input types rejected by schema validation

## How this service works

Parse an absolute URL into its WHATWG components: protocol/scheme, credentials, host/hostname/port, origin, pathname (plus path segments), search (plus a decoded query object) and hash. A string that is not a valid absolute URL is rejected as a clean 400.

## Output

A structured object containing all WHATWG URL components: protocol/scheme, username, password, host, hostname, port, origin, pathname, an array of path segments, the raw search/query string, a decoded query key-value object, and the hash/fragment. If the input is not a valid absolute URL, the endpoint returns a 400 error.
