  • US ISO interconnection queues and cited energy data. 25 free queries, then $49/mo or $490/yr.

  • exascale.build serves source-cited US energy data to AI agents over MCP and REST. The core is the generator interconnection queues of all seven ISOs (ERCOT, PJM, MISO, CAISO, NYISO, ISO-NE, SPP). Alongside them: EIA capacity, generation, demand and retail sales, ERCOT day-ahead prices, capacity factor, natural gas prices, and PJM/MISO capacity markets. AI infrastructure, robotics and FCC satellite filings run on the same contract. Every value returns its source, as_of date and source_url. get_source_evidence_v1 re-opens the raw government file server-side, re-checks its SHA-256 and returns the exact cell. 25 free queries with no key, then a paid key.
