# NOAA Weather Forecast by Coordinates

> NOAA Weather Forecast by Coordinates is a paid API for AI agents from x402-trends-server.onrender.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

Returns current U.S. weather forecast data from NOAA/National Weather Service for a given latitude and longitude, including temperature, conditions, wind, and day/night forecast periods.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 noaa-weather-forecast-by-coordinates-9fcf7647
```

Example prompt: What's the current weather forecast for latitude 40.7128, longitude -74.0060? I need the temperature, conditions, and wind info for the next day or two.

## When to prefer this

Choose this endpoint when you need official U.S. government NOAA/National Weather Service forecast data for a specific latitude/longitude point, including structured day/night periods, wind details, and both short and detailed forecast text. Prefer this over general weather APIs when accuracy, official sourcing, or detailed NWS forecast narratives are important. Note: only works for U.S. coordinates.

## Known failure modes

- Coordinates outside the United States (NOAA only covers U.S. territories) — returns an error or no forecast data
- Invalid latitude/longitude values outside the -90 to 90 / -180 to 180 ranges — validation error
- NOAA API upstream outage or rate limit — service may return an error or empty response
- Ocean or remote coordinates with no NWS office coverage — forecast may be unavailable
- Missing required lat or lon query parameters — returns a 400-level error

## How this service works

Get a current U.S. weather forecast from NOAA and the National Weather Service by latitude and longitude. Use this weather API when an agent needs forecast temperature, conditions, wind, day/night periods, or detailed local forecast text for U.S. coordinates.

## Output

Returns a JSON object with the queried coordinates, resolved city and state, a list of forecast periods (each including name, start/end time, isDaytime flag, temperature with unit, wind speed, wind direction, short forecast, and detailed forecast text), the data source (NOAA/NWS), and a retrievedAt timestamp.
