## 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 tollkit-weather-forecast-430468ba -d '<json body>'
```

Example prompt: What's the weather forecast for the next 7 days at latitude 38.98, longitude -76.49? Use Tollkit's pay-per-call weather endpoint — no account needed, just pay with USDC.

## When to prefer this

Choose this endpoint when you need quick, anonymous weather forecast lookups by GPS coordinates without registering for an account or managing API keys — ideal for agents that can pay micropayments in USDC via x402. Best for lightweight, pay-as-you-go use cases rather than high-volume or bulk forecast pipelines.

## Known failure modes

- Invalid or out-of-range latitude/longitude returns an error or empty forecast
- Payment failure or insufficient USDC balance blocks the response
- Requesting more than 14 periods is rejected (maximum enforced by schema)
- Coordinates in unsupported regions (e.g. mid-ocean or polar extremes) may return no data
- Network or upstream weather data provider outage results in a service error

## How this service works

Pay-per-call product page extraction. No account, no API key: pay in-band with x402 in USDC on Base or Solana.

## Output

Returns a list of up to 14 sequential 12-hour weather forecast periods for the specified coordinates, each containing conditions, temperatures, and other forecast data. Payment is processed inline via x402 protocol at $0.002 USDC per call — no account or API key required.
