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 weatherxm-agent-api-historical-weather-data-91fb53b3
```

Example prompt: What was the hourly weather like at latitude 37.98, longitude 23.73 on January 1st, 2025 — I need temperature, humidity, wind speed, and precipitation in metric units, with the Europe/Athens timezone.

## When to prefer this

Use this endpoint when you need granular hourly weather history for a specific geographic coordinate and date within the past 4 days. Prefer this over forecast endpoints when the date is in the past, and over current-weather endpoints when you need a full day's hourly breakdown rather than a snapshot.

## Known failure modes

- Date older than 4 days returns an error or empty data
- Invalid latitude/longitude range causes a 400 bad request
- Malformed date format (not YYYY-MM-DD) causes a validation error
- No weather station coverage near the requested coordinates may return sparse or null data
- Missing required query params (lat, lon, date) causes a 400 error

## How this service works

Historical weather data (up to 4 days)

## Output

A JSON object containing hourly weather records for the requested date and location, including temperature, humidity, wind speed, and precipitation values, plus the resolved location coordinates and timezone.
