## 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 x402-seo-serp-snippet-lookup-fb01d0e1
```

Example prompt: Pull the top SERP snippets for the keyword 'running shoes' — I want to see the titles, snippet text, and search intent for each result so I can plan my content strategy.

## When to prefer this

Choose this endpoint when you need real SERP snippet data (titles, descriptions, and search intent) for a specific keyword without building your own scraping infrastructure. It is ideal for on-demand, per-keyword lookups in SEO research, content planning, or competitive analysis workflows where paying a small per-call fee ($0.02 USDC via x402 on Base) is acceptable and programmatic SERP data access is needed quickly.

## Known failure modes

- Missing required 'keyword' query parameter returns a 400 or error response
- Invalid or unsupported 'hl' locale may return results defaulting to English or an error
- Payment not completed via x402 on Base results in 402 Payment Required response before data is returned
- Empty SERP results for highly niche or zero-volume keywords
- Rate limiting or worker timeout for very high request volumes
