EU Negative Electricity Price Prediction API
x402
EU Negative Electricity Price Prediction API is a paid API for AI agents from energy.netzhandwerker.de, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).
Predicts whether German/European electricity prices will go negative in the next 2 hours and recommends whether to act (shift load, charge EV, discharge battery, or trade).

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 a JSON object with: a boolean `negative_price_in_2h` prediction, a calibrated probability score (0–1), the recommended action string (e.g. 'execute_shift_to_target_window'), a `should_act` boolean, an array of time horizon objects with lead hours and probabilities, risk flags, a schema version, and an expiry timestamp indicating when the signal becomes stale.
Example use cases
EV smart charging automation
“Is now a good time to start charging my electric vehicle in Germany? I want to know if prices are likely to go negative in the next couple of hours, and what action you recommend — use a precision policy so we only act when the signal is strong.”
Home battery arbitrage decision
“My home battery is at 40% — should I charge it from the grid right now to lock in near-negative or negative electricity prices? Give me the probability and recommended action using the balanced policy profile.”
Energy trader alert system
“I'm trading European electricity spot contracts — tell me if there's a high probability of negative prices in the next 2 hours in Germany, and whether I should execute a position shift now. Use the recall policy so I don't miss opportunities.”
Technical details
Endpoint
POSThttps://energy.netzhandwerker.de/predict/negative-priceWhen to prefer
Choose this endpoint when you need a single, actionable go/no-go decision for a German or European energy flexibility asset (EV, battery, or trading position) based on a negative price prediction — rather than raw price data or carbon intensity metrics. It is ideal for autonomous agents that need a fast, cheap ($0.001 USDC), keyless signal with built-in decision logic and configurable risk policy profiles, avoiding the need to build your own prediction and threshold logic on top of raw market data.
Side effects
- Missing or malformed `policy_profile` enum value returns a validation error
- Payment not included or insufficient USDC causes x402 payment-required response
- Upstream grid data unavailable may result in degraded confidence or null expires_at
- Request body sent as wrong bodyType (e.g. form-data instead of json) causes parse failure
- Calling with GET instead of POST returns method-not-allowed
