## 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 toolbelt402-meta-url-metadata-seo-analysis-0f658d5d
```

Example prompt: Can you fetch the metadata and check for SEO issues on https://example.com — I want to know the page title and any problems like missing meta descriptions?

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call SEO audit or metadata extraction for a URL without setting up API keys. Ideal for agents doing quick page health checks, competitor analysis, or pre-publish audits using USDC micropayments on Base via x402.

## Known failure modes

- URL is unreachable or returns a non-200 status — may return an error or empty result
- Malformed or missing URL query parameter — likely returns a validation error
- Protected or bot-blocked pages may return incomplete metadata
- Rate limiting or payment failure via x402 protocol — call is rejected before execution
