GET /v1/funding/historical

unprobed

Historical per-venue funding rates for one crypto perpetual, aggregated 1h/4h/1d, across tracked CEX and DEX venues — the timeseries a funding-arb backtest needs. Up to 30-day windows (30-day retention). Edge-isolated: raw rates only, no spread or signal logic.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

curl -si -X GET 'https://api.usenami.io/v1/funding/historical' -H 'accept: application/json'

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.
