# Polyform Current Weather by US Coordinate

> Polyform Current Weather by US Coordinate is a paid API for AI agents from api.polyform.org, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-10).

Returns the latest observed weather conditions (temperature, wind, humidity, visibility, pressure) from the nearest NWS station for a given US coordinate.

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 polyform-current-weather-by-us-coordinate-deedb742
```

Example prompt: What are the current weather conditions — temperature, wind, and humidity — near coordinates 36.17°N, 86.78°W in Nashville?

## When to prefer this

Choose this endpoint when you need real-time, point-in-time observed weather conditions (not forecasts) for a specific US coordinate, sourced directly from the National Weather Service. It is ideal for current-moment decisions (logistics, events, field work) where historical or forecast data is insufficient. Prefer this over forecast endpoints when you only need what is happening right now at a location.

## Known failure modes

- No NWS station found near the given coordinate (coordinate outside US coverage area)
- Invalid or missing latitude/longitude query parameters returns an error
- Coordinate outside the contiguous US or territories with NWS coverage may return no data
- Station temporarily offline or data delayed — stale observation returned
- Payment failure (402) if USDC balance insufficient or x402 header not provided

## How this service works

Latest observed conditions near a US coordinate: temperature, wind, humidity, visibility, pressure from the nearest weather station. Source: National Weather Service. JSON.

## Output

A JSON object containing the latest observed conditions from the nearest NWS weather station: temperature in Fahrenheit (tempF), wind speed in mph (windMph), humidity percentage (humidityPct), a text description of sky conditions (conditions), and the NWS station identifier (station).
