OpenAPI Specification

exascale-build-webhooks-api-openapi.yml Raw ↑
openapi: 3.2.0
info:
  description: US ISO interconnection queues and cited energy data over MCP and REST. 25 free queries, then $49/mo or $490/yr (https://exascale.build/pro). Verified and source-cited. Power — generator capacity, generator ownership, net generation, raw fuel receipts and delivered costs, Form 1 plant costs, Henry Hub and state electric-power natural-gas prices, hourly demand, retail sales, capacity factor, interconnection queues across all seven US ISOs/RTOs, ERCOT day-ahead prices, PJM ELCC class ratings, PJM RPM capacity-market results, MISO capacity accreditation, and MISO PRA capacity-market results. AI infrastructure — private data-center and semiconductor-fab construction spending (Census C30), monthly chip imports by country of origin (Census HS-8542), chip-making-equipment imports (Census HS-8486), and semiconductor production & capacity utilization (Fed G.17). Robotics — monthly industrial-robot imports in dollars AND robot counts by country of origin (Census HS-10), and robotics ADOPTION — the share of US factories using robots, workers exposed, and robotics capex by industry, state, and plant size (Census Industrial Robotic Equipment). Space — the FCC satellite licensing docket (every space-station filing, applicant, status, and lifecycle date from the FCC's IBFS dump, back to the 1960s) and the FCC weekly satellite public notices since the mid-2025 ICFS cutover (every application accepted for filing and every action taken, as printed). Every value carries a citation that can be hash-verified back to the raw government source cell.
