## 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-events-serp-api-e2a36a24 -d '<json body>'
```

Example prompt: Search Google Events for jazz concerts in Austin, Texas happening this weekend and give me the list of results including names, dates, and links.

## When to prefer this

Choose this endpoint when you need programmatic access to Google Events search results (SERP) with per-call micropayment billing via x402/USDC, especially in Web3-native or AI agent workflows where pay-per-use crypto billing is preferred over subscription API keys. Ideal for agents that need event discovery without managing a dedicated SERP API subscription.

## Known failure modes

- Payment failure if insufficient USDC balance or x402 payment header is malformed
- Upstream Google SERP returning no results for obscure queries
- Rate limiting or blocking from the upstream SERP provider
- Invalid or missing query parameters causing empty or error responses
- Network timeout from the Vercel-hosted proxy to the upstream provider

## How this service works

## Output
