## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability polls-karbach-digital-german-electricity-data-a2ca4c77
```

Example prompt: What does Germany's electricity generation mix look like over the past 7 days — break it down by source, show the renewable share, consumption, and wholesale prices?

## When to prefer this

Use this endpoint when you need Germany-specific electricity data with source-level generation breakdown, renewable share, and wholesale pricing in a single call. Prefer it over generic energy APIs when the user specifically asks about the German electricity market, Energiewende progress, or German power prices. The built-in next-day price and 6-hourly refresh make it suitable for near-real-time monitoring.

## Known failure modes

- Invalid 'days' parameter (outside 1–365 range) returns a validation error
- Payment failure or missing x402 header returns 402 Payment Required
- Data may be up to 6 hours stale due to update cadence
- Source data unavailability may result in partial or missing fields for recent days

## How this service works

German electricity per day: generation by source, renewable share, consumption, wholesale price (incl. next day). Use when asked about German electricity: renewable share, generation mix, power prices, consumption. Source-attributed, German data, updated every six hours.

## Output

Returns a time series of daily records for Germany covering electricity generation broken down by source (e.g. wind, solar, coal, gas, nuclear), the share of renewables as a percentage, total consumption figures, and wholesale electricity prices including next-day pricing. Data is updated every six hours and can cover up to 365 days depending on the 'days' parameter.
