## When to prefer this

Choose this endpoint when you need historical electricity price data for a specific past time window — for backtesting battery arbitrage strategies, generating ESG cost reports, analyzing price volatility, or auditing energy procurement costs. Prefer this over the live/current price endpoint when retrospective data is required.

## Known failure modes

- Invalid or malformed period string returns 400 bad request
- Period out of available historical range returns empty result or 404
- Payment not processed (x402 protocol) returns 402 Payment Required
- Server unavailable returns 503
- Excessively long period range may time out or return partial data

## How this service works

Live electricity prices, carbon intensity, grid load, renewable share, flexibility windows, battery arbitrage, trading signals and ESG reporting for autonomous agents.

## Output

Returns historical electricity price data for the requested time period, likely including timestamped price values (e.g. EUR/MWh or similar units), covering day-ahead or spot market prices suitable for trend analysis, battery arbitrage optimization, and energy cost reporting.
