## 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 netzhandwerker-energy-buy-sell-signals-994c936d -d '<json body>'
```

Example prompt: Based on current electricity prices, grid load, and renewable share in Germany, should I charge my battery storage now or wait — give me a buy or sell signal with the underlying carbon intensity and arbitrage window.

## When to prefer this

Choose this endpoint when you need real-time, actionable electricity trading signals that combine price data with carbon intensity and grid load — especially for battery arbitrage, smart EV charging scheduling, or ESG-aware energy procurement decisions. Prefer this over generic price lookup endpoints when you need an integrated buy/sell recommendation rather than raw price data alone.

## Known failure modes

- Region or market not supported — returns 400 with unsupported region error
- Stale grid data — returns signal with degraded confidence flag if upstream data is delayed
- Invalid trading parameters — returns 422 with parameter validation error
- Payment not included or insufficient — returns 402 Payment Required
- Rate limit exceeded — returns 429 with retry-after header

## How this service works

One x402 call returns the action, best time window, expected EUR value, confidence and expiry for German and European electricity decisions. USDC on Base, no API key or account.

## Output

Returns structured buy/sell trading signals for electricity, including current spot price, carbon intensity score, grid load percentage, renewable energy share, recommended action (buy/sell/hold), arbitrage window timing, flexibility scores, and ESG metrics relevant to the current grid state.
