## When to prefer this

Choose this endpoint when you specifically need an hourly Washington, DC weather forecast without having to specify coordinates, and you want each data point labeled by its production method (NWS vs. bias-blended station model). It is preferable to a generic point forecast endpoint when DC is your fixed target and you value the methodological transparency or the bias-calibration layer the provider applies.

## Known failure modes

- Requested hours exceeds maximum (240) — validation error returned
- Invalid units value (not 'metric' or 'imperial') — rejected with schema error
- NWS upstream outage — may return partial data or error
- Network timeout if upstream data source is unavailable
- Payment not received or insufficient USDC — 402 Payment Required

## How this service works

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

## Output
