# Human? See it work in 10 seconds — no setup: https://exascale.build/try # Agent? Read on. # exascale.build > 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. The customer is an AI agent, not a human dashboard. Call `list_capabilities_v1` first to discover what's queryable, then the matching query tool; pass any returned citation to `get_source_evidence_v1` to prove a number against its raw source row. ## Access 25 free queries, then $49/mo or $490/yr — https://exascale.build/pro The first 10 need no key; the next 15 come with a free key sent to an email entered at https://exascale.build/free. Both are one-time, not a daily refill: the 10 per network address, the 15 per key. The homepage demo (https://exascale.build) is separate: 10 questions a day. Four PJM/MISO capacity-market data points require a paid key on every query. A past as_of (vintage history) requires a paid key; the latest snapshot is included in the free queries. ## Connect - [MCP endpoint](https://api.exascale.build/mcp): streamable-http — call list_capabilities_v1 first -

Example: - `GET https://api.exascale.build/v1/power/capacity/query?state=TX&group_by=fuel_group&order_by=nameplate_mw&top_n=5` Rules: repeated keys become lists; `group_by` accepts comma-separated field names; for fully-typed queries pass `q=` — exactly the POST body. Discover each data point's filters at `GET https://api.exascale.build/v1///schema` (paths in /v1/capabilities). POST with a JSON body remains the canonical form. ## Subscribe to changes - `POST https://api.exascale.build/v1/webhooks/subscriptions` — get a signed webhook when a data point you track publishes a new snapshot (the `snapshot.promoted` event: new as_of + row-count delta). Requires an API key; subscriptions are owner-scoped. Full schema: /openapi.json ## Verify Every value resolves to a raw source row via `get_source_evidence_v1` (SHA-256 checked). The tools return data, not opinion — no editorializing in outputs.
