Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-battery-arbitrage-optimizer-13b4d41f -d '<json body>'
```

Example prompt: Calculate the battery arbitrage schedule for my 13.5 kWh home storage system with a round-trip efficiency of 0.92 — I want to know the best charge and discharge windows and expected profit based on live electricity prices.

## When to prefer this

Use this endpoint when you need to compute actionable battery charge/discharge schedules and profit estimates for energy arbitrage, specifically when you have a battery's capacity and efficiency on hand and want real-time electricity market data factored into the optimization. Prefer this over generic energy price endpoints when the goal is battery storage monetization rather than just price lookup.

## Known failure modes

- Missing required fields (capacity_kwh or efficiency) returns 400 validation error
- Efficiency value outside 0–1 range may cause computation error
- Live price data temporarily unavailable causes 503 service error
- Negative or zero capacity_kwh returns invalid input error
- Payment not provided or insufficient triggers 402 payment required

## 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 optimal charge and discharge windows, expected arbitrage profit, trading signals, and scheduling recommendations based on current electricity spot prices and the supplied battery's capacity and efficiency parameters.
