## 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-cfc2f00d
```

Example prompt: Can you search Yelp for the top-rated Italian restaurants in Chicago, Illinois and show me their ratings, addresses, and price levels?

## When to prefer this

Choose this endpoint when you need structured Yelp business data — ratings, reviews, hours, and contact info — without requiring a Yelp API key or account setup. Ideal for agents that need on-demand, pay-per-call local business discovery without subscription overhead. Prefer over direct Yelp API integration when minimizing credential management matters, or when operating in a micropayment-native x402 environment.

## Known failure modes

- No results returned if the search term or location is too specific or misspelled
- Payment failure if USDC balance or x402 wallet is insufficient
- Rate limiting or empty response if Yelp data is unavailable for a region
- Malformed query parameters may return an empty or error response
- Stale data if Yelp listing has not been recently updated
