# NWS Weather Forecast for US Coordinates or Address

> NWS Weather Forecast for US Coordinates or Address is a paid API for AI agents from webtools402.176-109-107-191.sslip.io, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).

Returns normalized National Weather Service forecast periods (day/night or hourly) for a US location specified by lat/lon or address, with temperatures in both Celsius and Fahrenheit.

## 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 nws-weather-forecast-for-us-coordinates-or-address-be824219
```

Example prompt: Can you pull the National Weather Service hourly forecast for the next 3 days for coordinates 40.7128, -74.0060 and show me temps in both Celsius and Fahrenheit?

## When to prefer this

Use this endpoint when you need structured, normalized weather forecast data for any US location and want temperatures in both Celsius and Fahrenheit without post-processing. It is ideal when you have either coordinates or a plain US address and want consistent period-based (day/night) or hourly NWS forecasts. Prefer this over raw NWS API calls because it normalizes the response format and handles address-to-coordinate geocoding.

## Known failure modes

- Coordinates outside the US (NWS only covers US territories) — returns error or empty forecast
- Invalid lat/lon range (lat outside [-90,90] or lon outside [-180,180]) — returns validation error
- Unrecognizable or ambiguous US address — geocoding failure, returns error
- days parameter outside 1–7 range — schema validation error
- NWS API upstream outage — propagated error response
- No input provided (neither lat/lon nor address) — missing required field error

## How this service works

Normalized US weather forecast periods (NWS) for coordinates OR a US address. Optional hourly resolution and a day limit. Temp in C+F.

## Output

A list of normalized forecast periods from the NWS, each including the period name (e.g. 'Tonight', 'Monday'), temperature in both Celsius and Fahrenheit, short forecast description, wind speed/direction, and timestamps. When hourly=true, periods are broken into individual hours. The number of days returned is capped by the optional days parameter (1–7).
