Hey HN, I built this API to help engineers and data scientists quantify 'predictability' and detect drift in their datasets. The link goes to the live Swagger docs so you can see the JSON structure and endpoints. Note: The API endpoints require a key, but you can test the underlying math/engine for free on the homepage (no signup required) to see how the scoring works. I used Python and Numba for the backend to handle the statistical heavy lifting. Happy to answer any questions about the implementation!
