# Rebase Grid API

> Open REST API for European power system and electricity market time series: day-ahead prices,
> load, generation by type, wind and solar forecasts, cross-border flows, balancing and grid
> frequency, from ENTSO-E, TSOs and exchanges, in one schema. No API key and no sign-up are needed:
> every endpoint answers without a key at 30 requests per minute per IP address. A free key raises
> the limit to 240 per minute.
