## 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-posts-serp-api-6d6acf81 -d '<json body>'
```

Example prompt: Can you pull the latest Google Maps posts for 'Shake Shack Madison Square Park' so I can see what updates or promotions they've recently shared?

## When to prefer this

Use this endpoint when you need Google Maps posts/local updates for a specific business and want pay-per-call pricing with no subscription commitment, paid in USDC via the x402 protocol. Ideal for agents that make infrequent or unpredictable requests and need Web3-native micropayment access to SERP data.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment rejected — returns 402 Payment Required
- Invalid query: malformed path or query parameters result in empty or error response from upstream
- Business not found: no Google Maps posts exist for the queried location
- Rate limiting: upstream SERP provider throttles requests — returns 429 or error passthrough
- Upstream provider outage: SERP data unavailable, returns 502 or empty body

## How this service works

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

## Output

Returns the upstream SERP provider's response containing Google Maps posts for the queried business or location, including post text, dates, images, and call-to-action details, passed through after successful $0.01 USDC payment.
