## 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-philadelphia-hourly-weather-forecast-451342c0
```

Example prompt: Give me the hourly weather forecast for Philadelphia for the next 72 hours in imperial units, including temperature, precipitation probability, and wind.

## When to prefer this

Choose this endpoint when you need ready-to-use hourly weather data specifically for Philadelphia without having to supply coordinates, and when forecast method transparency (NWS vs. bias-blended station) matters. It is preferable to generic weather APIs when you want a calibrated, bias-corrected forecast with labeled data provenance, and it is simpler than the generic /v1/forecast/point endpoint since Philadelphia coordinates are already built in.

## Known failure modes

- Invalid hours value outside 1–240 range returns a validation error
- Invalid units enum value returns a bad request error
- NWS upstream outage may cause degraded or delayed forecast data
- Payment failure (x402) blocks the response if USDC payment is not completed
- Requesting beyond 168 hours may return data but with reduced accuracy warnings

## How this service works

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

## Output

An array of hourly forecast records for Philadelphia covering up to the requested horizon (default 48h, max 240h). Each record includes timestamp, temperature (imperial or metric), precipitation probability, wind speed and direction, and a method label indicating whether the data point came from the NWS model or the bias-blended calibrated station model.
