Every stream Dryos collects
135 live streams across seven US grid operators, the National Weather Service and four Texas permit offices — 133,593 nodes, zones, stations and fuels in all. Somebody maintains each one: it is pulled straight from the operator that publishes it, and every number is compared against that operator's own file before it is served. Free to read over HTTP or through an AI agent, with no key and no sign-up.

- Every timestamp is UTC, and interval_start_utc is the start of the interval. Convert only for display.
- Null means the source did not report it — never zero.
- Forecasts keep every publication. Each interval's newest vintage is returned by default; vintages are never averaged together.
- Entity names are verbatim, inner spaces included. Look one up rather than guessing it.
The full set is on the API reference, and at /llms.txt for an agent.
