## 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 halowerk-energy-dispatch-planner-0423d81c -d '<json body>'
```

Example prompt: Find me the cheapest power window in Germany to run a 4 kWh GPU training job that must finish before 11pm tonight — give me the exact start time, expected EUR cost, and how confident you are in the forecast.

## When to prefer this

Use this endpoint when you need to schedule an energy-intensive workload (compute, DePIN, battery charge, or power trade) in Germany or Europe and want an actionable, optimized dispatch window with cost and savings estimates. Prefer this over raw spot-price lookup endpoints when you need a concrete decision (start time, cost, savings) rather than just market data. Best when the workload has a hard deadline and you want the system to reason over the forecast and return a recommended window with uncertainty and trace.

## Known failure modes

- No viable dispatch window found before the specified deadline — returns an error or empty plan
- Deadline too near for meaningful optimization — endpoint may return a zero-savings plan or warning
- Invalid workload type or unsupported region — returns a validation error
- Stale market data — freshness timestamp indicates data may be outdated, increasing uncertainty
- Payment not settled (x402 micropayment failure) — request is rejected before processing
- Excessive demand estimate outside modeled range — returns out-of-bounds error

## How this service works

Schedules a deadline-bound compute, DePIN, battery or power-trading workload into an actionable German or European power window. Returns exact timing, expected EUR cost and savings, uncertainty, freshness, expiry and decision trace.

## Output

Returns an actionable dispatch plan including: the exact recommended start time and duration for the workload, the expected EUR cost, estimated EUR savings versus immediate execution, a forecast uncertainty score, a freshness and expiry timestamp for the plan, and a human-readable decision trace explaining why the window was selected.
