Output
Returns a JSON object with a schema version, expiry timestamp, calibrated negative-price probabilities for 2h, 4h, and 6h horizons, a reviewed threshold profile matched to the chosen policy_profile, and a decision_engine object containing an executable response policy indicating recommended actions.
Example use cases
Battery dispatch during negative price window
“What's the likelihood of negative electricity prices in the next 2 and 4 hours? I want to know if my grid-connected battery should stop charging right now — use the precision policy profile so I only act on high-confidence signals.”
EV smart charging pause decision
“Check whether German power prices are likely to go negative in the next 6 hours and give me an action policy — I want my EV fleet charging software to automatically pause sessions if the probability is high enough. Use the recall policy profile.”
Energy trading agent risk assessment
“I need calibrated negative-price probabilities across the 2h, 4h, and 6h horizons for the German electricity market right now, with a utility policy profile, so my trading bot can hedge exposure before the evening peak.”
Technical details
Endpoint
POSThttps://energy.halowerk.com/predict/negative-priceWhen to prefer
Choose this endpoint when an agent needs actionable, calibrated probability estimates for negative electricity prices across multiple near-term horizons (2h/4h/6h) rather than raw spot prices or historical data. Ideal for battery storage controllers, EV charging schedulers, and power-trading bots that require a reviewed threshold policy and an executable response recommendation rather than just a price figure. Prefer this over sibling endpoints that return raw EPEX spot prices or event feeds when probabilistic risk quantification and automated decision support are the goal.
Side effects
- Invalid policy_profile enum value returns 422 validation error
- Missing or malformed request body returns 400 bad request
- Expired or unpaid x402 payment header causes 402 payment required response
- Upstream ENTSO-E or SMARD data unavailability may cause 503 or stale expiry_at
- High load or backend model timeout returns 504 gateway timeout
