# PayAI AgentsTools Weather (NWS)

> PayAI AgentsTools Weather (NWS) is a paid API for AI agents from payai.agentstools.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).

Returns current US weather conditions (temperature in °C and °F, humidity, wind, pressure, and description) from the National Weather Service for a given coordinate pair or auto-geocoded US address.

## 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 payai-agentstools-weather-nws-362e5b35
```

Example prompt: What are the current weather conditions — temperature, humidity, and wind — for 1600 Pennsylvania Ave NW, Washington, DC?

## When to prefer this

Use this endpoint when you need real-time, authoritative US weather conditions from the National Weather Service and your input is either a lat/lon coordinate pair or a US street address. Prefer this over general weather APIs when you need official NWS data, dual Celsius/Fahrenheit output, and support for address-based lookups via auto-geocoding — all in a single call.

## Known failure modes

- Non-US coordinates or address returns an error since NWS only covers the United States
- Ambiguous or unrecognizable address fails geocoding and returns no data
- Coordinates outside [-90,90] lat or [-180,180] lon are rejected by schema validation
- NWS API outage or rate limit may cause upstream failures
- Missing both lat/lon and address results in a missing required parameter error

## How this service works

Current US weather conditions (temp in C+F, humidity, wind, pressure, description) from the NWS for coordinates OR a US address (auto-geocoded).

## Output

A JSON object containing current temperature in both Celsius and Fahrenheit, relative humidity percentage, wind speed and direction, atmospheric pressure, and a human-readable weather description sourced from the National Weather Service.
