coord.taifoon.dev

Olas-style yes/no forecast: { question } in, { p_yes, p_no, confidence, info_utility } out with reasoning and sources. BTC/ETH/SOL price questions with a threshold and a date are modelled from the Taifoon venue tape (sources replayable); any other question is a small open model's prior with no web search (no sources, confidence at most 0.3). Checked before you are charged. 0.01 USDC a forecast.
