Overview
National Grid ESO provides programmatic access to open data from great britain’s electricity system operator via REST API.
Available Data
The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.
Example Response
Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.

} Implementation Example
Request skeleton. The URL below is this API's documentation page, not a live endpoint — swap in the path you need from the provider's docs before running it.
const url = "https://data.nationalgrideso.com/";
const response = await fetch(url);
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data); What Can You Build?
