## 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-table-headers-extractor-7042141e -d '<json body>'
```

Example prompt: Can you pull out the table headers from the profile table on this page: https://example.com/user-directory — I want to know what columns they use for their profile data.

## When to prefer this

Use this endpoint when you need to specifically extract header/column-name text from profile or data tables within a webpage, either by passing a public URL for live fetching or by supplying raw HTML directly. Prefer this over general CSS-selector endpoints when you want table headers without specifying a custom selector. Use the free sandbox variant (/v1/sandbox/profile-table-headers) first to verify results before paying $0.005 USDC per call.

## Known failure modes

- URL is not publicly accessible or returns 4xx/5xx — extraction fails
- HTML contains no table headers or table elements — empty result returned
- URL blocked by SSRF protection (private IP ranges, localhost) — rejected with error
- HTML input exceeds 200,000 character limit — request rejected
- URL malformed or too short (under 8 characters) — validation error
- Page uses JavaScript-rendered tables that aren't in static HTML — headers may not be found

## How this service works

Call when an agent needs th text extracted from a public page or HTML (SSRF-safe). Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/profile-table-headers first.

## Output

Returns an array or list of header text values extracted from profile/data tables found in the provided URL or HTML, representing the column names or field labels present in the table structure.
