## 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-x402-api-gateway-weatherstack-proxy-a0e038ef -d '<json body>'
```

Example prompt: Can you get me the current weather conditions for London using the Weatherstack proxy — I want temperature, weather description, and humidity?

## When to prefer this

Choose this endpoint when you need pay-per-use weather data without a long-term Weatherstack subscription, when operating in a web3/crypto-native context where USDC micropayments are preferred over API key billing, or when building agentic workflows that need to pay for data atomically per request.

## Known failure modes

- Insufficient USDC balance causes payment failure and 402 response
- Invalid or missing path/query parameters result in upstream Weatherstack errors
- Weatherstack API key exhausted or invalid on the provider side returns an upstream error
- Malformed query object causes request parsing failure
- Location not found by Weatherstack returns an error object instead of weather data

## How this service works

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

## Output

Returns the raw Weatherstack API response passed through after successful x402 micropayment, including current weather fields such as temperature, weather descriptions, humidity, wind speed, and other meteorological data for the queried location.
