Overview

This catalog page exposes the physical schema, coverage, and latest source rows without inventing a normalized grain for publisher-shaped snapshot fields. Use the documented key and event time when comparing revisions or vintages.

Query contract

Select the latest ingested_at revision per event_time and location_id. Filter to a recent interval before describing a flow as current.

Analysis rules

Preserve ISO-NE's published sign and interface label. Do not infer import/export direction from the sign without the named interface convention.
actual_flow, current_schedule, purchase, sale, total_imports, and total_exports are related flow views, not additive categories.

Access

Query from your own tools

Use the guarded HTTP endpoint directly, or connect an MCP client and load the dataset contract with describe_data before calling query_data.
