  "description": "Generated by API Evangelist (pipeline-university) from live probes. Envelope returned by every JSON distribution on www.opendata.polimi.it. Confirmed identical across all 25 distributions fetched live on 2026-09-01: a single object with one property, `recordset`, holding an array of flat row objects. The response body is UTF-8 WITH a byte-order mark, so a strict parser must decode as utf-8-sig before parsing. Row keys are dataset-specific Italian column labels and are not shared between datasets. Derived by API Evangelist from live responses; not published by the institution.",
