Latest ERCOT hub and load-zone prices (public).

GET 
/v1/power/ercot/prices

For each of ERCOT's 15 hub and load-zone settlement points: the latest 5-minute SCED LMP, the latest 15-minute real-time settlement point price (the RT perps' settlement basis), and the RT perpetual listed on the point. Reference data collected from ERCOT's public display reports — not an index input. A price is null until first observed and stale when flagged invalid upstream or older than 20 min (LMP) / 40 min (SPP). Values are µUSDC per MWh and may be negative.
