## 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 orthogonal-openmart-local-business-search-5bf8f516 -d '<json body>'
```

Example prompt: Find me highly rated woman-owned coffee shops in Austin, Texas with at least 50 reviews and a minimum rating of 4.5 — return the top 10 results.

## When to prefer this

Choose this endpoint when you need to discover local businesses using natural language queries combined with structured filters like minimum rating, review count, ownership type, or geo bounding — especially when 22+ filter categories are needed. Prefer over generic web search when you want structured, filterable business data rather than unstructured web results.

## Known failure modes

- No results returned for overly specific filter combinations (high min_rating + high min_reviews in a small area)
- Geo object malformed or missing causing location-unanchored results
- Invalid ownership_type value returning empty or error response
- Page size too large causing timeout or truncated response
- Query too ambiguous returning irrelevant business categories
