Api Endpoint

api.usenami.io

Next funding payment ETA for one crypto perpetual on one venue, with the current indicative funding rate alongside — when the next settlement lands and where the rate stands now. Entry-timing input for funding-arb and carry trades. Not a payment forecast: the endpoint takes no position side or size, and the rate can move before settlement.
