## 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 swift-bot-labs-toolbox-web-metadata-extractor-1aa9808e
```

Example prompt: Can you fetch the web metadata for https://github.com/ — I want the Open Graph image, page title, favicon, and basic SEO info like H1 count and title length?

## When to prefer this

Choose this endpoint when you need lightweight, structured metadata extraction (OG tags, title, favicon, basic SEO signals) from a URL without requiring a full browser scrape or JavaScript rendering. It's ideal for link preview generation, SEO audits, content enrichment pipelines, and social sharing validation. It requires no API key — just a USDC micropayment per call — making it convenient for ad-hoc or agent-driven workflows.

## Known failure modes

- Invalid or unreachable URL returns error with ok:false
- Non-HTTP/HTTPS URLs are rejected (only GET or HEAD supported)
- Pages blocking automated requests (bot protection, CAPTCHAs) may return empty or partial metadata
- Missing OG tags result in null og.image or og.title fields
- Payment failure (insufficient USDC balance) returns HTTP 402 before request is processed
- Timeout on slow-loading pages may produce incomplete results

## How this service works

62 small, deterministic utility APIs (DNS and e-mail checks, web extraction, EVM decoding, x402 checks, IP math, JSON/CSV, hashing, conversions). No account or API key: pay per call in USDC with x402.

## Output

Returns a JSON object with 'ok' status, tool name, and a 'result' containing: Open Graph data (og.image, og.title), SEO signals (seo.h1Count, seo.titleLength), the resolved URL, the full page title, and the favicon URL.
