## 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 openweb-ninja-yelp-business-search-x402-3fcf0e8e

Example prompt: Can you search Yelp for the top-rated sushi restaurants in San Francisco's Mission District, filtering for places with at least 4 stars and open right now?

## When to prefer this

Choose this endpoint when you need live, structured Yelp business data including ratings, reviews, contact info, and hours for local businesses — especially restaurants, services, and retail. Prefer it over generic web search when you need machine-readable structured data (ratings, coordinates, phone numbers) rather than HTML pages, and when you want Yelp-specific social proof metrics. Ideal for AI agents that need to answer 'what's nearby and well-reviewed' questions without requiring an API key or account setup.

## Known failure modes

- Invalid or unrecognized location parameter
- Payment of $0.003 USDC not settled via x402 — request rejected with 402 status
- Rate limiting or Yelp API quota exceeded upstream
- Malformed query parameters returning empty or error response
