GET /v1/perp/funding-next

live

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.

Verdict: live. The unpaid GET reached a valid 402 (confirmed by the re-probe of 2026-10-01).

The catalog declares GET. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
