## 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 agentshelf-syntexa-ch-css-anchor-text-extractor-91984502 -d '<json body>'
```

Example prompt: Can you grab all the anchor text from the links on https://example.com/blog — I want to see what the hyperlinks say on that page?

## When to prefer this

Use this endpoint when you need to extract anchor text specifically from <a> elements on a public webpage or raw HTML, and the unpaid sandbox POST /v1/sandbox/css-a-text is unavailable or rate-limited. Prefer the sandbox endpoint for free usage first. Choose this over general text extraction endpoints when you specifically need hyperlink/anchor text rather than body text or other element content.

## Known failure modes

- URL is private/internal or resolves to a metadata address (SSRF blocked)
- URL is unreachable or returns non-200 status
- HTML is malformed or contains no anchor elements, returning empty results
- Input exceeds maximum length (URL > 2048 chars, HTML > 200000 chars)
- Payment not provided or insufficient (x402 payment required for paid tier)
- URL scheme is unsupported (e.g. file://, ftp://)
