How this service works
Returns licensed ENTSO-E and SMARD spot-market context for compute, DePIN, battery and power-trading agents: published day-ahead prices, volatility, load, renewable share when available, the observed share of published negative-price hours, uncertainty, freshness and expiry.
Output
A structured market brief containing: published day-ahead electricity spot price, price volatility metric, current grid load, renewable energy share (when available), observed share of negative-price hours, uncertainty score, data freshness timestamp, and cache expiry — all sourced from licensed ENTSO-E and SMARD data feeds.
Example use cases
Compute cost optimization by price signal
“Before spinning up my GPU cluster, pull the current day-ahead electricity price and volatility for the German market so I can decide if now is cheap enough to run or if I should wait for a better window.”
Battery charge scheduling at low-price hours
“I'm managing a grid-connected battery — get me today's day-ahead spot prices and the share of negative-price hours for the French market so I can schedule charging during the cheapest periods.”
Power-trading agent market context
“My power-trading agent needs the latest SMARD day-ahead price, renewable share, grid load, and uncertainty score for the European spot market before it places any bids — can you fetch that brief now?”
Technical details
Endpoint
POSThttps://energy.halowerk.com/v3/market-briefWhen to prefer
Choose this endpoint when an AI agent needs authoritative, licensed European electricity spot-market data (ENTSO-E/SMARD) with freshness and uncertainty metadata before making energy-sensitive decisions — such as scheduling compute workloads, optimizing battery charging, or executing power trades. Prefer it over generic energy APIs when you need negative-price hour statistics, renewable share context, and structured uncertainty signals in a single call designed for agentic workflows.
Side effects
- Data not yet published for requested delivery date (day-ahead market window not yet cleared)
- Requested region not covered by ENTSO-E/SMARD licensed feeds
- Stale or unavailable upstream data resulting in low freshness score or error
- Invalid or unrecognized market region parameter
- Payment failure (x402 USDC payment not completed or insufficient)
