Changelog

All notable improvements and extensions to the Meteonorm API are documented here.

Note that we won't make any breaking changes to API version /v1. If breaking changes are inevitable, we will release a new version at /v2 while keeping /v1 stable.

2025-07-31

• The /v1/forecast and /v1/observation endpoints now support a response_format query parameter. The available response formats are csv and json.
• The /v1/climate endpoint offers new response formats: csv, epw, tmy3, and pvsyst.

2025-07-02

• All API endpoints now return 400 "bad request" if the URL query string contains non-existent parameters. For example: /v1/forecast/precision?xxxxx=123&... will return a 400 error.
