## 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 synthora-weather-now-820fc2bf -d '<json body>'
```

Example prompt: What's the current weather in Madrid — temperature, humidity, wind, and whether it's trending warmer or cooler over the next 6 hours?

## When to prefer this

Choose this endpoint when you need a quick, no-auth, low-cost current weather snapshot with an actionable 6-hour temperature trend for any global city or coordinate pair. It is especially useful for agents that need to make short-term decisions (e.g. outdoor activity planning, logistics routing) based on whether conditions are improving or worsening. Prefer this over full forecast APIs when only current conditions and near-term trend direction are needed, not multi-day forecasts.

## Known failure modes

- Unrecognized city name returns an error or empty result
- Invalid lat/lon values outside valid ranges cause a parsing failure
- Open-meteo.com upstream outage results in no data returned
- Ambiguous city names (e.g. Springfield) may resolve to an unexpected location
- Malformed input string (missing comma between lat and lon) causes a lookup failure

## How this service works

SYNTHORA weather-now: current weather for any city or lat,lon — temperature, feels-like, humidity, wind, WMO condition code in plain text, plus the 6h temperature trend (rising/falling/flat), which is the actionable part. Free source: open-meteo.com (ECMWF/NOAA/DWD), no API key, timestamped.

## Output

A plain-text response containing: current temperature, feels-like temperature, humidity percentage, wind speed, WMO weather condition code, a 6-hour temperature trend label (rising/falling/flat), and a timestamp — all sourced from open-meteo.com using ECMWF/NOAA/DWD model data.
