## 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 quant-agent-shop-local-business-search-2210d8c3 -d '<json body>'
```

Example prompt: Find me coffee roasters in Portland, OR — I need their names, addresses, ratings, and websites so I can compare a few options.

## When to prefer this

Choose this endpoint when you need structured local business listings with coordinates, ratings, phone numbers, and websites for a specific type of business in a specific location. It excels at comparison tasks (e.g. finding the highest-rated plumber in a city) and location-aware discovery. Prefer it over general web search when you need machine-readable business data rather than unstructured results, and over mapping APIs when you want enriched business profiles in a single call without managing Google Maps API credentials.

## Known failure modes

- Query too short (under 2 characters) or too long (over 200 characters) returns validation error
- No businesses found for the given query/location combination returns empty results array
- Invalid country code format (not lowercase 2-letter ISO) returns validation error
- Invalid language code format returns validation error
- Page number out of range (must be 1–5) returns validation error
- Network or upstream Google Maps/Serper outage may cause failure; failed calls are not charged

## How this service works

Local business search. Send what and where in one query, such as coffee roasters in Portland OR; returns up to 20 Google Maps business listings with name, address, coordinates, category, rating and review count, phone and website. Use to find or compare local businesses. Business listings only, not for finding people. Typical response about 1 s. Failed calls are not charged.

## Output

A JSON object containing the original query, the data source attribution (Google Maps via Serper), a timestamp, and an array of up to 20 business listings each with: name, address, latitude/longitude coordinates, Google Maps CID, business category, star rating, review count, phone number, website URL, and position in results.
