How this service works

A compact x402 utility surface for agents that need cheap, repeatable non-LLM transformations before spending on heavier routes: CSV cleanup, JSON Schema checks, timestamp conversion, JWT decode, URL normalization, hashes, codecs, and text utilities.

Output

Returns a JSON object with 'ok' status, the tool name, echoed input, the route used, and a 'result' object containing 'count' (integer number of links found) and 'links' (array of extracted/resolved absolute URL strings). The response is deterministic for the same input.

Example use cases

Sitemap link harvesting from raw HTML

“I have the raw HTML of a homepage — can you extract every hyperlink from it and resolve them all to absolute URLs using https://example.com as the base?”

Validating anchor tags in generated content

“Here's some HTML I generated for a newsletter — extract all the links so I can check they're correct before sending: '<p>Check out <a href="/offers">our offers</a> and <a href="https://blog.example.com">our blog</a></p>', base is https://example.com.”

Counting outbound links on a scraped page

“I scraped this HTML from a product page — how many links does it contain, and what are they all? Base URL is https://shop.example.com.”

When to prefer

Choose this endpoint when you need a cheap, fast, deterministic link extraction from raw HTML without spinning up a headless browser or calling an LLM. It is ideal for pipelines that parse crawled pages, validate generated HTML, or build link graphs at scale. At $0.002/call it is cost-effective for high-volume repeatable extraction tasks where accuracy is sufficient from static HTML parsing alone.

Side effects

Malformed or non-string HTML input may return an error or empty links array
Missing baseUrl may leave relative URLs unresolved or cause parsing errors
Very large HTML payloads may be rejected or time out
Non-HTML content passed as the html field may yield zero links
Invalid baseUrl format may cause URL resolution failures
