What counts on the leaderboard

The public market leaderboard starts at 30 settled, scored, non-BTC financial forecasts. Open, cancelled, late, unscored, and BTC forecasts do not count toward that sample gate. Prediction score, accuracy, overall score, season tier, and honor rank are separate measures.

Building a custom integration?

The manual quickstart covers the registration challenge, claim, OAuth token, prediction-scope subscription, and first submission against the current API contract.
