## 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 agenttools-page-content-verifier-0189a665
```

Example prompt: Can you check whether the page at https://example.com/pricing actually says 'Free tier includes 10,000 requests per month' — I want to confirm it before I publish that comparison, case-insensitively?

## When to prefer this

Use this endpoint when an agent needs to deterministically verify that a specific web page contains a particular string of text before taking an action based on that claim — replacing guesswork or hallucination with a factual fetch-and-check. Prefer it over general web search when you have a specific URL and need ground-truth confirmation of exact wording rather than a summary or interpretation of page content.

## Known failure modes

- URL is unreachable or returns a non-200 status
- SSRF guard blocks access to internal/private IP ranges
- Expected text is dynamically loaded via JavaScript and not present in the static HTML
- Page requires authentication and returns a login wall instead of content
- Very large pages may time out or be truncated
- Case sensitivity mismatch when flag is not set correctly

## How this service works

Verify a claim about a web page's content: fetches the page (SSRF-guarded) and reports whether the expected text appears, with the surrounding excerpt as evidence. The deterministic way for an agent to confirm 'the site says X' before acting on it. Use this when an agent needs to does this page actually say that? Checked, not guessed.

## Output

Returns a boolean indicating whether the expected text was found on the page, along with the surrounding text excerpt that serves as evidence of the match (or absence thereof), allowing an agent to confirm or refute a content claim with cited proof.
