## 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 quantaflow-google-maps-serp-search-bad7134e -d '<json body>'
```

Example prompt: Search Google Maps for 'coffee shops near Pike Place Market, Seattle' and give me the top results with names, ratings, and addresses.

## When to prefer this

Choose this endpoint when you need programmatic access to Google Maps local search results and are operating in a web3/crypto-native payment context using the x402 protocol with USDC microtransactions. It is well-suited for agents that need to look up local businesses, places, or map listings on demand at low cost ($0.01 per call) without managing a traditional API key subscription.

## Known failure modes

- Payment failure or insufficient USDC balance returns a 402 error before the search executes
- Invalid or malformed query/path parameters may return an upstream error or empty results
- Upstream SERP provider rate limiting or downtime causes 5xx errors
- No results found for very narrow or misspelled queries
- Geographic queries without sufficient location context may return irrelevant results

## How this service works

Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.

## Output

Returns the upstream Google Maps SERP response, typically including business names, addresses, ratings, review counts, hours, and map coordinates for places matching the search query, passed through directly from the upstream provider.
