# OpenWeather Current Conditions

> OpenWeather Current Conditions is a paid API for AI agents from openweather-coral.vercel.app, paid per call via x402, $0.002/call, down (last probed 2026-10-12); live alternatives: NWS Multi-Period Weather Forecast ($0.001) and Weather Forecast ($0.001).

Agents call it through Zero, which pays per call: no API key and no wallet of your own. New accounts start with $5.

Returns real-time weather conditions for a city or coordinates, including temperature, feels-like, humidity, wind, pressure, visibility, and sunrise/sunset times

## 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 openweather-coral-vercel-app-233d77f2
```

Example prompt: What's the current weather in London right now — temperature, feels-like, humidity, and wind conditions?

## When to prefer this

Use this endpoint when you need a single, comprehensive snapshot of current weather conditions for a specific location — temperature, wind, humidity, pressure, visibility, and sunrise/sunset all in one call. Prefer this over forecast endpoints when historical or future data is not needed. Choose city-name querying for convenience or lat/lon for precision. If air quality data is also needed, pair with the sibling AQI endpoint.

## Known failure modes

- Unknown city name returns an error — use lat/lon instead for ambiguous city names
- Missing required city or lat/lon parameter results in a 400 bad request
- Rate limiting or payment failure (402) if USDC balance is insufficient
- Stale data if OpenWeatherMap upstream is delayed — check updated_at field
- Lat/lon outside valid ranges (-90 to 90, -180 to 180) may return an error

## How this service works

Current weather conditions for any city: temperature, feels-like, humidity, wind, pressure, visibility, sunrise/sunset

## Output

A JSON object with the city name, country, coordinates, current temperature (with min/max and feels-like in Celsius), humidity percentage, atmospheric pressure, visibility in meters, wind speed/direction/gust, cloud cover percentage, precipitation (rain/snow last hour), a weather description and icon code, and UTC timestamps for sunrise, sunset, and last data update.
