Columns
Exactly what a request answers with, read from the API rather than written here.
| Column | Type | Description |
|---|---|---|
| interval_start_utcrequired | timestamp | Start of the interval, UTC. Always UTC — ERCOT publishes wall-clock Central with a repeated-hour flag, which is resolved on ingest.e.g. 2026-08-29T14:15:00Z |
| isorequired | string | Publishing ISO.e.g. ERCOT |
| zonerequired | string | ERCOT weather zone, in the actual-load report's spelling.e.g. COAST |
| temperature_frequired | number | Forecast temperature, degrees Fahrenheit.e.g. 83.7 |
| source_published_at_utcrequired | timestamp | When ERCOT posted the document this row came from, UTC. For reports republished on a rolling window this is the vintage: the same interval appears once per publication, and the newest is the current view.e.g. 2026-08-29T14:17:01Z |
| collected_at_utcrequired | timestamp | When Dryos collected this row, UTC. Stamped by the platform, not the collector.e.g. 2026-08-29T14:18:02Z |

Ask an agent
The same stream through the Model Context Protocol, so Claude, ChatGPT, Cursor or any MCP client can query it directly.
claude mcp add --transport http dryos https://api.dryos.ai/mcpThen ask:
What has Temperature been at COAST over the last 24 hours, and when did it peak?
Setup for every client is on the MCP server page.
How this stream is checked
- Pulled straight from ERCOT MIS · NP4-722-CD — no reseller in between — and compared against that file before it is served.
- Null means the source did not report it — never zero.
- A reading lands daily, rolling window; the interval timestamp is the start of the interval, in UTC.
- ERCOT settles and publishes on US Central time. Every timestamp Dryos serves is UTC.
