## 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-mark-extractor-94921aed -d '<json body>'
```

Example prompt: Can you extract all the marked/highlighted text from this page: https://example.com/article — just pull out whatever is inside the <mark> tags?

## When to prefer this

Use this endpoint when you need to extract specifically the text content of HTML <mark> (highlight) elements from a webpage or raw HTML. Prefer this over a general text extractor when you need only highlighted/marked content. Note: a free sandbox alternative at POST /v1/sandbox/profile-mark should be tried first before incurring the $0.009 USDC charge.

## Known failure modes

- URL is unreachable or returns a non-200 status — extraction fails with an error
- SSRF-blocked URL (private IP ranges, localhost) — rejected for security reasons
- No <mark> elements present on the page — returns empty result
- HTML input exceeds 200,000 character limit — request rejected
- URL shorter than 8 characters or longer than 2048 characters — validation error
- Malformed HTML may result in incomplete or no extraction

## How this service works

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

## Output

Returns the extracted text content found within HTML <mark> elements from either a fetched public URL or provided raw HTML. The response contains the mark text strings found on the page, enabling downstream processing or analysis.
