Api Endpoint

api.usenami.io

Funding-rate sign-change detection for one crypto perpetual — every positive↔negative flip across venues inside a lookback window, each with its venue, hour and the rates either side of the change. Raw events for spotting funding-regime turns in funding-arb and carry positioning: it reports the flips, it does not classify them as sustained or transient.
