      "description": "Wholesale US electricity-market prices made agent-callable. One x402 call returns the real-time and day-ahead wholesale power price ($/MWh) by market hub, the day-ahead-vs-real-time spread, the 24-hour high/low range, the count of negative-price intervals, price volatility, and a CHEAP / NORMAL / ELEVATED / SCARCE / SPIKING signal — plus a battery-arbitrage read (best intraday spread, negative-price frequency). This is the price of the ELECTRON: the missing counterpart to ComputePulse (price of compute) and distinct from GridPulse (grid demand/mix/stress). The read a data-center-siting, battery-dispatch, energy-trading, or compute-cost agent needs on what power actually costs right now and how volatile it is. Pair it with ComputePulse to reason about the compute-power spread. $0.05 in USDC on Base via x402. Source: US ISO public data (CAISO OASIS live; ERCOT / PJM / MISO rolling out).
