Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-openweather-gateway-54722dc0 -d '<json body>'
```

Example prompt: Fetch the current weather conditions and temperature for London using the QuantaFlow OpenWeather gateway — I'm fine paying $0.01 USDC per call.

## When to prefer this

Choose this endpoint when you need OpenWeatherMap data and want to pay per-call with USDC via the x402 protocol rather than managing a traditional API key subscription — ideal for AI agents or web3 workflows where crypto micropayments are preferred over monthly billing.

## Known failure modes

- Payment failure: insufficient USDC balance or wallet not configured for x402 protocol
- Invalid path: incorrect OpenWeatherMap API path segment resulting in 404 from upstream
- Invalid query parameters: missing required OpenWeatherMap fields like city name or API key
- Upstream API error: OpenWeatherMap returns an error (e.g. invalid location, rate limit)
- Gateway timeout: upstream OpenWeatherMap service is slow or unavailable

## How this service works

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

## Output

The raw upstream OpenWeatherMap API response body (JSON weather data including temperature, conditions, humidity, forecasts, etc.) passed through after successful x402 USDC micropayment verification, along with the content type header.
