What is OutcomeTick?
OutcomeTick archives Polymarket and Predict.fun crypto Up/Down market data. Its documentation distinguishes event and receive timestamps, preserves missing intervals and exposes per-file checksums and market settlement metadata.
Those records support research into what data was available at a given moment. Coverage is specific to the listed assets, intervals and archive dates; it is not a general history of every Polymarket question.
