How this service works
Live wholesale electricity prices, demand, and generation mix across 25 grids in the US, UK, Australia, and Europe. Pay-per-call API access from $0.001.
Output
A JSON object containing an array of timestamped capacity data points for the requested zone, each with a Unix timestamp, numeric value, and unit (e.g. GBP/MWh or MW). Also includes zone identifier, total count, metric name (capacity), license, and data attribution.
Example use cases
Monitor grid capacity for energy trading
“Get me the GridHub capacity data for US-ERCOT for the past 6 hours so I can see how available capacity has been trending before market close.”
Compare capacity across European zones
“Fetch the latest capacity readings from GridHub for France, Germany, and Spain — I want to compare how they stack up right now.”
Alert when Australian grid capacity drops
“Check the current capacity value for the AU-NSW zone on GridHub and let me know if it's below 500 MW — I'm watching for low-capacity conditions.”
Technical details
Endpoint
GEThttps://api.grid-hub.app/v1/capacity/%7Bzone%7DWhen to prefer
Use this endpoint when you need a time-series of capacity data for a specific electricity grid zone, particularly when you want to specify a time window or retrieve a bulk set of historical data points. Prefer this over snapshot endpoints when trend analysis or time-series storage is the goal. If you only need the current latest value, consider the /latest or /snapshot endpoints instead.
Side effects
- Invalid or unsupported zone enum value returns an error — must use one of the 25 supported zone IDs
- Missing required zone path parameter returns a 400 or 404 error
- Payment not provided or insufficient (x402 protocol) returns a 402 Payment Required — use 'sample=true' for a free truncated response
- Start/end timestamps in wrong format or out of range may return empty data or an error
- Requesting more than 5000 rows via limit param may be rejected or silently capped
