# AgentsTools Weather API

> AgentsTools Weather API is a paid API for AI agents from api.agentstools.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).

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

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 agentstools-weather-api-3e2a3c06
```

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

## When to prefer this

Choose this endpoint when you need real-time US weather conditions from the authoritative National Weather Service source, especially when you only have a street address (not coordinates) since it auto-geocodes. Prefer this over generic weather APIs when NWS accuracy and dual Celsius/Fahrenheit output are important, or when working within an x402 micropayment workflow.

## Known failure modes

- Address not found or outside the US — geocoding fails with an error
- Coordinates outside the US coverage area of NWS — no data available
- Invalid lat/lon range (lat outside [-90,90] or lon outside [-180,180]) — validation error
- NWS upstream service temporarily unavailable — 502 or timeout
- Neither lat/lon nor address provided — missing required parameter error
- Payment not received or insufficient — x402 payment required 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 weather conditions including temperature in both Celsius and Fahrenheit, relative humidity percentage, wind speed and direction, atmospheric pressure, and a short human-readable weather description (e.g. 'Partly Cloudy'), sourced from the National Weather Service.
