Polymarket Demo Data

The honest demo loop: format-check on the free sample, shape your pipeline on the open snapshot, validate endpoints on Starter, and only then buy the window your production question actually needs.

Each stage costs nothing and answers one question; the ordering prevents the classic mistake of paying for a window whose format you never inspected.

Demo data proves format, not performance: a snippet of one market cannot certify a strategy, and the honest reading of any demo is "the shape of the data exists" — which is exactly what a builder needs before committing.

A demo confirms format, cadence, and access — not performance. The free CSV slice proves the column shape, the open Zenodo snapshot proves the 250ms grid at 897,192 rows, and Starter proves the endpoint contract. The one thing no demo can certify is a strategy, and the honest framing keeps that boundary explicit.

The ordering matters: anyone who pays for a window before checking the format has already made the mistake the demo exists to prevent.
