## 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-twitter-site-meta-extractor-9ec897f6 -d '<json body>'
```

Example prompt: Can you extract the twitter:site meta tag from https://example.com for me? I need the Twitter handle that's embedded in that page's metadata.

## When to prefer this

Use this endpoint when you need to reliably extract only the twitter:site meta tag from a public webpage or raw HTML, with SSRF protection built in. Prefer the free sandbox POST /v1/sandbox/profile-twitter-site first to avoid charges. Choose this paid endpoint when the sandbox is unavailable or rate-limited, or when you need guaranteed reliability for production workloads.

## Known failure modes

- Page is not publicly accessible or returns a non-200 status — extraction fails
- URL is blocked by robots.txt or firewall — no content retrieved
- HTML content too large (exceeds 200,000 character limit) — request rejected
- No twitter:site meta tag present in the page — returns empty/null result
- Invalid or malformed URL provided — request validation error
- SSRF-blocked URL (internal/private IP range) — request rejected for safety

## How this service works

Call when an agent needs twitter:site extracted from a public page or HTML (SSRF-safe). Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/profile-twitter-site first.

## Output

Returns the extracted twitter:site meta tag value (typically a Twitter handle like @username) found in the page's HTML head section. If no twitter:site tag is present, returns an empty or null result. The response is billed at $0.006 USDC per call.
