Cite

Cite kardashev if you used the Python package, the JS/TS client, or the hosted API client. Cite the ISO/RTO (and EIA where relevant) for the underlying observations.

This is a software citation. It is not a DOI for a frozen US ISO dataset. Production LMP on data.kardashevlabs.org is a rolling window. Do not write “data obtained from Kardashev Labs” as if the live API were an archival record.

GitHub renders the same metadata from CITATION.cff on the Python repository (Cite this repository). DOI: https://doi.org/10.5281/zenodo.21988476 . Concept DOI (all versions): https://doi.org/10.5281/zenodo.21988475 .

What not to cite this as

• Not an official ISO study, queue, or forecast.
• Not a substitute for citing CAISO, ERCOT, MISO, NYISO, ISO-NE, SPP, PJM, or EIA.
• Not a citable snapshot of live LMP history beyond what the hosted API actually retains.
