## 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-serp-google-flights-deals-14f7061d -d '<json body>'
```

Example prompt: Search Google Flights for the best deals from New York JFK to London Heathrow departing July 15 and returning July 22, economy class.

## When to prefer this

Use this endpoint when you need programmatic access to Google Flights search results (SERP data) for a specific route and date, especially in a web3/crypto-native agent context where micropayment per query via USDC is preferred over subscription-based flight data APIs. Ideal for travel agents, trip planners, or price comparison workflows that need live Google Flights data on demand.

## Known failure modes

- Payment failure (insufficient USDC balance or x402 protocol error) results in 402 Payment Required response
- Invalid query parameters or malformed path yield upstream API errors
- No results found for a specific route or date combination
- Rate limiting or upstream SERP API quota exhaustion
- Unsupported origin/destination airport codes
- Network timeout from upstream Google Flights SERP provider

## How this service works

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

## Output

Returns a passthrough of the upstream Google Flights SERP API response, including flight options with pricing, airlines, departure and arrival times, layovers, and deal indicators for the queried route and dates.
