DC Hub

Grid Intelligence

get_grid_intelligence

Read-onlyIdempotent

Use this whenever the user asks about grid capacity, demand or reliability for one grid region. Call when the user asks about power availability, headroom or time-to-power in a US ISO (PJM, ERCOT, CAISO, MISO, SPP, NYISO, ISO-NE) or a market's grid. Returns live demand, fuel mix, queue depth, DCPI excess-power and constraint scores, time-to-power, reserve margin. avg_time_to_power_months and avg_queue_wait_months are DIFFERENT measurements; quote the one you mean. With a free key, a few full briefs a day; keyless gets a trimmed preview. Unlimited needs a paid key. Ex: "PJM headroom for 200 MW?" iso must be a US ISO (ERCOT, PJM, CAISO, MISO, SPP, NYISO, ISO-NE); other codes return region_not_covered. Free = preview.

Input Schema

TableJSON Schema

Name	Required	Description
`iso`	No	Alias for region_id — the ISO/RTO or balancing-authority code
`market`	No	Market NAME or metro slug instead of a grid code, e.g. "Ashburn", "northern-virginia", "dallas". Resolved to its ISO through the published DCPI market row before the brief is built; the answer carries a resolved_from block naming what it resolved to. Not an alias for region_id — "Ashburn" is not a grid code.
`region`	No	Alias for region_id — the ISO/RTO or balancing-authority code
`mpp_pay`	No	Stripe MPP step 1: true returns a signed per-call payment challenge (a quote; no money moves) instead of the free preview. Agents only.
`region_id`	No	Grid region (required): one of the 7 US ISOs (PJM, ERCOT, CAISO, MISO, SPP, NYISO, ISO-NE), an EIA balancing-authority code (e.g. SOCO, DUK, AZPS, TVA), or the PJM Dominion zone region_id="PJM-DOM" for live Ashburn / Northern Virginia zone load + real-time LMP (the Ashburn / Northern Virginia zone, not visible in EIA)
`mpp_credential`	No	Stripe MPP step 2: the Shared Payment Token minted for challenges[0]; pays that challenge for this one call.

Output Schema

TableJSON Schema

Name	Required	Description
`ok`	No	true when the ISO lookup executed
`iso`	No	ISO / grid operator code
`as_of`	No	Timestamp of the reading
`quota`	No	Caller quota state (remaining calls, tier).
`taste`	No	Free-tier preview fields
`_entity`	No	Payload class (facility\|market\|iso_grid\|queue_results\|deal\|report\|response); branch on it.
`cite_as`	No	Ready-made attribution line
`citation`	No	How to attribute DC Hub: {source, url, license, cite_as, retrieved_at}, or the attribution line as a string.
`iso_name`	No	Grid operator full name
`withheld`	No	Fields withheld on this tier
`provenance`	No	Source, method, as_of, verification_counts, license, cite_as; quote it when citing.
`_front_door`	No	First-tool hint: plan_query(intent) returns the ordered plan.
`_return_loop`	No	Next-session delta call (get_changes).
`completeness`	No	Share of the payload this tier got
`demand_period`	No	Period of the demand reading
`withheld_total`	No	How many fields were withheld
`free_preview_only`	No	true when only the free preview was served
`site_evaluation_handoff`	No	Follow-up calls [{tool, parameters, why}] when the payload carries coordinates.
