# DWD Climate Normals by Coordinate

> DWD Climate Normals by Coordinate is a paid API for AI agents from natur.halowerk.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Returns German Weather Service (DWD) reference-period climate normals for the nearest station to a given coordinate, including monthly means and annual totals for temperature, precipitation, and sunshine, plus annual counts of frost, ice, summer, and hot days.

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 dwd-climate-normals-by-coordinate-3a200a99 -d '<json body>'
```

Example prompt: What are the DWD climate normals for the location at 52.52°N, 13.41°E — give me the monthly temperature means, annual precipitation total, sunshine duration, and the yearly counts of frost days, ice days, summer days, and hot days.

## When to prefer this

Choose this endpoint when you need authoritative, long-term DWD reference-period climate baselines (normals) for a specific geographic point in Germany — ideal for agricultural planning, construction siting, environmental assessments, or energy feasibility studies where historical averages matter more than current or forecast conditions.

## Known failure modes

- Coordinate outside Germany or DWD station coverage area — no station found, error returned
- Invalid or missing latitude/longitude values — request validation error
- No reference-period data available for the nearest station — partial or empty response
- Network timeout or service unavailability — 5xx error

## How this service works

Returns the German Weather Service reference-period values for the station nearest a coordinate: monthly means and annual totals for air temperature, precipitation and sunshine duration, plus the mean annual counts of frost days, ice days, summer days and hot days.

## Output

A structured response containing the DWD reference-period climate normals for the station nearest the submitted coordinate: monthly mean air temperatures, monthly and annual precipitation totals, monthly and annual sunshine duration, and mean annual counts of frost days (Tmin < 0°C), ice days (Tmax < 0°C), summer days (Tmax ≥ 25°C), and hot days (Tmax ≥ 30°C).
