Dryos

Every stream Dryos collects, with its entity column and headline measure. Args: domain: Energy, Weather or Property. operator: A grid operator — ERCOT, MISO, PJM, SPP, CAISO, NYISO or ISO-NE. search: A word matched against the slug, name and tagline ("lmp", "wind", "permits").

One stream in full: every column, the primary key, the source and its health. Also what changed in the collector recently — a change in the collector is a change in the data, and a step in a series may be one. Args: slug: The stream, e.g. ercot-realtime-lmp (list_streams names them).

Look up the nodes, zones, stations or fuels in a stream, with how far back each goes. Use it before query_stream: names are verbatim and never to be guessed. `facets` counts the entities by type. Args: slug: The stream. search: Case-insensitive substring of the entity name ("HOUSTON", "HB_", "KAUS"). entity_type: Only one type — HUB, LOAD_ZONE, RESOURCE_NODE, INTERFACE… limit: At most this many (1–2000).

The distinct values of one text column, most rows first — what a filter can be. Args: slug: The stream. column: A text column from describe_stream (not the entity — use find_entities). where: Filters as `column=value`, the same as query_stream's. search: `column:text`, a case-insensitive substring. limit: At most this many (1–500).

Read rows from a stream — raw (newest first), each entity's newest, or a rollup. The result carries `restUrl`: this same request as a plain GET on the public REST API, ready to put in an app. Args: slug: The stream. node: The entity, whatever the stream calls it (node, zone, station, fuel). System-level streams have none. start: Inclusive, ISO-8601 or relative to now (-24h, -7d). UTC. end: Exclusive, same forms. interval: Bucket s
