## 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-profile-header-extractor-43fd25b4 -d '<json body>'
```

Example prompt: Can you extract the profile header text from https://example.com/about — just the main header section at the top of the page?

## When to prefer this

Use this endpoint when you need to extract the header or profile header text from a public webpage by URL or from raw HTML, with SSRF protection guaranteeing no internal network access. Prefer the unpaid sandbox variant (POST /v1/sandbox/profile-header) for testing. Choose this paid endpoint when you need reliable, production-grade extraction with guaranteed execution. If you only need the h1 text specifically, the sibling h1-extraction endpoint at $0.007 may be more appropriate and cheaper.

## Known failure modes

- URL is not publicly accessible or returns a non-200 status
- URL resolves to a private/internal IP address (blocked for SSRF safety)
- HTML is malformed or does not contain a recognizable header element
- Input exceeds size limits (URL > 2048 chars or HTML > 200,000 chars)
- No header element found in the provided HTML or page
- Network timeout when fetching the URL

## How this service works

Call when an agent needs header text extracted from a public page or HTML (SSRF-safe). Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/profile-header first.

## Output

Returns the extracted header/profile header text found in the page or HTML. The result is the textual content of the page's header section, stripped of HTML markup, suitable for further processing or display.
