## 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 x402-factory-denver-hourly-weather-forecast-7d83c92e
```

Example prompt: Pull me the hourly Denver weather forecast for the next 72 hours in imperial units — I need temperature, rain probability, and wind.

## When to prefer this

Choose this endpoint when you specifically need a pre-built hourly Denver forecast without supplying coordinates, and want transparency about whether each hour was produced by a raw NWS model or the bias-blended calibrated station model. Prefer this over a generic point-forecast endpoint when Denver is always your target location and you value per-data-point method attribution.

## Known failure modes

- Invalid 'hours' parameter outside 1–240 range returns validation error
- Invalid 'units' value (not 'imperial' or 'metric') returns 400 bad request
- NWS upstream outage may cause partial or degraded data
- Payment failure (insufficient USDC balance) results in 402 response and no data returned
- Forecast beyond ~168 hours may have reduced coverage or fallback to NWS-only model

## How this service works

Hourly Denver weather forecast (blend model, method labeled) — Hourly weather forecast for Denver: temperature, precipitation probability, and wind, up to 168 hours out. NWS-derived series, bias-blended with our calibrated station model where covered — every response labels the method that produced it. Same shape as /v1/forecast/point with the Denver coordinates built in.

## Output

An hourly time-series array of weather data for Denver covering up to 168 hours (or the requested number of hours up to 240), with each entry containing temperature, precipitation probability, wind speed and direction, and a label indicating which model method (NWS-derived or bias-blended calibrated station) produced that data point. Units match the requested unit system (imperial or metric).
