api record

GridHub provides live and historical electricity market data — wholesale prices, demand, interconnector flows and installed capacity — for 25 grid zones across the US, Europe, Great Britain and Australia, in one normalised JSON schema. Generation mix is published for GB and US-CAISO only and carbon intensity for GB only; other zones omit those metrics. Every response carries its source attribution and licence; repeat them when presenting data. Start with get_zone_brief for 'right now' questions and get_history for time series. Authentication: send 'Authorization: Bearer <ghk_key>' on the MCP connection (free key, 500 requests/day, instant email signup at https://grid-hub.app/developers), or pay per call with x402 (USDC on Base) via the X-PAYMENT header. With no credentials, data tools run in free sample mode: real, current data but truncated (history capped at 50 rows; brief returns one context block). Sample results are clearly marked.

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 6 tools
3 open 3 never probed 3 of 6 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • get_map_snapshot open 2h ago

    Current headline values for all 25 zones in one call — the cheapest way to compare zones (e.g. 'which European zone has the lowest price right now', 'rank US ISOs by demand'). Rebuilt every 5 minutes. Authentication: send 'Authorization: Bearer <ghk_key>' on the MCP connection (free key, 500 requests/day, instant email signup at https://grid-hub.app/developers), or pay per call with x402 (USDC on Base) via the X-PAYMENT header. With no credentials, data tools run in free sample mode: real, current data but truncated (history capped at 50 rows; brief returns one context block). Sample results are clearly marked.

  • get_status open 2h ago

    Ingestion health per source and zone: last successful fetch timestamp and last error, if any. Free. Use it to explain stale or missing values before drawing conclusions from them.

  • list_zones open 2h ago

    List the 25 electricity grid zones GridHub covers, with id, name, data source (EIA, ENTSO-E, NESO, AEMO), timezone, currency, licence and required attribution. Free, no credentials needed. Call this first if you are unsure which zone id to use.

  • get_latest unknown never probed

    The most recent value of every metric one zone publishes (price and demand for every zone; generation by fuel for GB and US-CAISO; carbon intensity for GB; interchange where available), each with unit and timestamp. This is the right tool for 'what is the price/demand/carbon intensity in X right now'. Note: some European sources publish day-ahead prices, so the price timestamp can be up to ~36h in the future; use get_zone_brief for a strictly at-or-before-now value with historical context. Authentication: send 'Authorization: Bearer <ghk_key>' on the MCP connection (free key, 500 requests/day, instant email signup at https://grid-hub.app/developers), or pay per call with x402 (USDC on Base) via the X-PAYMENT header.

  • get_zone_brief unknown never probed

    Composite, interpretation-ready snapshot of one zone: current price / demand / carbon intensity where published (strictly at-or-before now), each ranked against that zone's own last ~30 days (percentile, vs-median %, min/max, sample count and the actual data window), a 24h trend per metric, the generation mix where published (GB, US-CAISO), and a one-sentence plain-English summary. Best tool for questions like 'is electricity cheap/clean in X right now' or 'is this a good time to run a flexible workload'. A raw price means little without this context. Authentication: send 'Authorization: Bearer <ghk_key>' on the MCP connection (free key, 500 requests/day, instant email signup at https://grid-hub.app/developers), or pay per call with x402 (USDC on Base) via the X-PAYMENT header.

  • get_history unknown never probed

    Time series for one metric in one zone over a start/end window (Unix seconds). Rows are returned oldest-first and the 'limit' truncates from the OLDEST end, so a small limit over a wide window returns old data, not recent data — for 'the latest N points' set start close to now, or use get_latest / get_zone_brief for current values. Default window is the last 24h (last ~400 days for capacity, which is annual). Max window 31 days per call (400 for capacity); paginate with start/end for more. Metrics: price (wholesale, local currency per MWh), demand (MW), generation (per fuel, 'fuel' field set; % or MW depending on zone; GB and US-CAISO only), carbon-intensity (gCO2/kWh; GB only), interchange (net imports, MW), capacity (installed MW per fuel; European zones only). Authentication: send 'Authorization: Bearer <ghk_key>' on the MCP connection (free key, 500 requests/day, instant email signup at https://grid-hub.app/developers), or pay per call with x402 (USDC on Base) via the X-PAYMENT header.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
