## 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-css-anchor-title-extractor-b351c91b -d '<json body>'
```

Example prompt: Can you pull all the anchor title attributes — the a[title] values — from this page: https://example.com/about?

## When to prefer this

Use this endpoint when you specifically need the title attribute values of anchor tags (a[title]) from a webpage or HTML blob, with built-in SSRF safety. Prefer this over generic HTML parsers when you want a focused, paid-per-call microservice without managing your own scraping infrastructure. If cost is a concern, try the free POST /v1/sandbox/css-a-title first.

## Known failure modes

- URL is not publicly accessible or returns non-200 status
- HTML input exceeds 200,000 character limit
- URL is blocked by SSRF protection (internal/private IP ranges)
- Page has no anchor elements with title attributes, returning empty result
- Malformed URL or HTML input rejected by schema validation
- Payment of $0.003 USDC not settled, returning 402

## How this service works

Call when an agent needs anchor titles via a[title] from a public page or HTML (SSRF-safe). Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/css-a-title first.

## Output

A list of title attribute values extracted from all anchor (a[title]) elements found in the provided URL or HTML. Returns an array or structured set of title strings found on the page, or an empty result if none are present.
