How this service works
Interactive Bitcoin 4-year halving cycle chart on a polar disc. Live price, 200W MA, Mayer Multiple, RSI, MACD, Pi Cycle and optional paid cycle projections.
Output
A JSON object containing an array of hourly forecast records, each with timestamp, temperature in Celsius, precipitation in mm, precipitation probability, wind speed and gust in km/h, wind direction in degrees, cloud cover percentage, sunshine minutes, a condition label, and a weather icon identifier. Also includes the resolved DWD station metadata and attribution text.
Example use cases
City weather forecast for event planning
“What's the hourly weather forecast for Hamburg over the next 72 hours? Use latitude 53.55 and longitude 9.99 with the Europe/Berlin timezone — I need temperature, rain probability, and wind speed.”
DWD station direct query
“Fetch me the weather forecast directly from DWD station 00399 (Berlin-Alexanderplatz) for the next 24 hours in the Europe/Berlin timezone.”
Multi-day forecast for outdoor logistics
“Get me 5 days of hourly weather data for Munich — lat 48.1351, lon 11.582 — in UTC timezone, so I can plan outdoor operations across the week.”
Technical details
Endpoint
GEThttps://4yearcycle.com/x402/weather-de?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured hourly weather forecasts sourced from Germany's official meteorological authority (DWD) for locations in Germany or Central Europe. It is ideal when DWD MOSMIX accuracy and official attribution are required, or when you want to query a specific DWD station by ID. Prefer it over generic weather APIs when regulatory or scientific credibility of the data source matters, or when coverage of German stations is the priority.
Side effects
- Missing or invalid lat/lon without a station ID provided — returns error
- Station ID not found in DWD database — returns null station or error
- Hours value above 240 gets capped silently — may return fewer records than expected
- Invalid timezone string causes parsing error
- DWD MOSMIX data unavailable or delayed — upstream data gap
