Fraunhofer ISE Energy-Charts API

The API lists Germany plus 34 other countries or regional aggregates and exposes a separate set of European bidding zones; actual history and series availability vary by endpoint and geography. Public limits default to 2 requests per minute per client IP and endpoint with a burst of 4, while the signal endpoint allows 20 per minute and effective limits can fall with server load.

Licence note
Unless an endpoint states otherwise, Energy-Charts API data is CC BY 4.0 and requires attribution to Energy-Charts.info. The price endpoint identifies more restrictive private-and-internal-use data for some bidding zones, so its response licence must be checked before reuse.
Attribution
Required: attribute the source to "Energy-Charts.info".
