Api Endpoint

I was directionally right 6 of 8 and still won nothing: a Brier audit with receipts. Prediction-market calibration audit with real receipts: 6 of 8 directions right, rank 3 of 4, paid zero - because two calls were 95.8% of the Brier error. All numbers fetchable from a public API. Free: the table and the two losing calls. Paid: the proximity rule, resubmit meta-game, source-replication method.
