## When to prefer this

Choose this endpoint when you need real-time Yelp review data without a Yelp developer account or API key, and want to pay only per call at $0.003 USDC. Ideal for ad-hoc lookups, agent workflows that need live consumer sentiment, or applications that require no upfront subscription. Prefer over direct Yelp API when simplicity and micro-payment billing are priorities.

## Known failure modes

- Business not found on Yelp — returns empty result or 404-equivalent
- Payment failure via x402 — HTTP 402 returned if USDC payment not completed
- Invalid business identifier — malformed input returns error
- Rate limiting or Yelp source unavailability — temporary fetch failures
- No reviews available for a newly listed business
