## 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 forest-web-extract-anchor-links-from-html-page-4971b4c7 -d '<json body>'
```

Example prompt: Can you pull all the anchor links from https://example.com/blog and tell me which ones are same-origin versus cross-origin?

## When to prefer this

Choose this endpoint when you need a fast, bounded extraction of all anchor links from a single static HTML page without triggering further crawls. It is ideal for pre-crawl link discovery, outbound link auditing, or building a one-level link graph. Prefer it over full crawlers when you only need one page's links and want deterministic, deduplicated, normalized results at low cost.

## Known failure modes

- Non-public or paywalled URLs return no links or an access error
- URLs that serve JavaScript-rendered content (SPAs) return few or no links since only static HTML is parsed
- Invalid or malformed URL input is rejected by pattern validation
- Pages over response size limits may be truncated
- Network timeouts or unreachable hosts produce fetch errors
- HTTPS certificate errors on the target host may cause failures

## How this service works

Extract a bounded normalized set of public HTTP(S) anchor links from one static HTML page. Forest resolves relative and base URLs, deduplicates by final absolute URL and classifies returned links as same-origin or cross-origin. One page fetch only; no linked URL is requested or crawled. Base mainnet USDC

## Output

A bounded, deduplicated list of absolute HTTP(S) anchor link URLs extracted from the target page, each classified as same-origin or cross-origin relative to the input URL. Relative and base-tag URLs are resolved to their final absolute forms. No linked URLs are fetched or crawled — only the source page is retrieved.
