## 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-portland-hourly-weather-forecast-96d4b3c9
```

Example prompt: Can you pull the hourly Portland 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 an hourly weather forecast for Portland with transparent method labeling (NWS vs. bias-blended station model) and don't want to supply coordinates. It is more convenient than the generic /v1/forecast/point endpoint for Portland-specific use cases, and the bias-blending provides calibrated accuracy improvements over raw NWS data. Prefer this over generic weather APIs when auditability of the forecast method matters.

## Known failure modes

- Invalid 'hours' value outside 1–240 range returns a 400 validation error
- Invalid 'units' enum value (not 'imperial' or 'metric') returns a 400 error
- NWS upstream outage may result in degraded or partial forecast data
- Payment not provided or failed results in 402 Payment Required
- Forecast coverage beyond ~168 hours may have reduced accuracy or availability

## How this service works

Hourly Portland weather forecast (blend model, method labeled) — Hourly weather forecast for Portland: 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 Portland coordinates built in.

## Output

A time-series array of hourly forecast objects for Portland, each containing: timestamp, temperature (in requested units), precipitation probability (%), wind speed and direction, and a method label indicating whether the data point was produced by the NWS model or the bias-blended calibrated station model. Forecast horizon is up to 168 hours (or up to 240 hours if requested, subject to availability).
