ZDR: A registry for the data AI endpoints retain

Why it surfaced

This is a sharply focused public registry for a consequential but slippery claim: whether an AI endpoint keeps prompts, completions, or other request residue. Its scores are lower-is-better, dated, and accompanied by letter grades and markers such as server-side, filtering, or regional conditions.

ZDR scores zero-data-retention claims for AI models, platforms, and products at the endpoint level.
