## 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-reviews-api-7df6ab4b
```

Example prompt: Can you pull the Yelp reviews for 'The French Laundry' in Yountville, CA so I can see what customers have been saying about it recently?

## When to prefer this

Choose this endpoint when you need Yelp-specific review data for a local business without wanting to manage API keys or monthly subscriptions. It is ideal for pay-as-you-go AI agent workflows where individual calls are infrequent but review data quality matters. Prefer this over Google Maps reviews when Yelp's review corpus is specifically relevant (restaurants, local services, hospitality). The x402 micropayment model at $0.003/call makes it cost-effective for low-volume lookups.

## Known failure modes

- Business ID or name not found on Yelp — returns empty or error response
- Payment failure via x402 if USDC balance is insufficient — returns 402 status
- Rate limiting or Yelp scraping blocks causing partial or no data returned
- Malformed input parameters resulting in a 400-level error
- Business has no reviews — returns empty reviews array
