Editor's take on Carbon Intensity API
Built for developers and energy teams whose scheduling logic needs Great Britain grid carbon intensity, with regional forecasts more than 96 hours ahead behind a public OpenAPI. It is a data source rather than a measurement tool: it reports grid intensity, not the energy a workload drew, so attribution and estimation stay in the caller's own code. Coverage is Great Britain only, which means multi-country operations need complementary providers. Use is licensed CC BY 4.0 with attribution obligations. Teams needing measured per-service emissions should pair it with a metering library.

Fits web product teams that want carbon budgets enforced where regressions happen, in CI, by running a browser scenario, recording CPU activity, network traffic, memory and elapsed time, and failing the analysis past a threshold. The trade-off is scope and licensing: the method models page delivery and client execution rather than server-side energy, and the CLI package is published as UNLICENSED, which matters for redistribution or embedding. Enterprise terms are quoted on request. Teams without CI discipline, or needing whole-estate accounting, should pair it with code-level and infrastructure measurement.
