How this service works
Cross-venue rate spread snapshot for a symbol
Output
A cross-venue snapshot for the requested symbol (e.g. BTC) showing the current funding rates per venue, identifying the highest and lowest rate venues, and the total spread expressed in basis points — useful for funding arbitrage and carry trade analysis.
Example use cases
Cheapest venue for ETH long
“I'm planning to open a long ETH perpetual position — which exchange has the lowest funding rate right now, and how wide is the spread across all tracked venues in basis points?”
Spot funding arbitrage opportunity
“Can you check if there's a meaningful funding rate arbitrage opportunity for SOL across all perp exchanges right now? I want to know the best and worst venues and the current spread so I can decide whether it's worth putting on a carry trade.”
Compare BTC perp funding venues
“Before I roll my BTC short into a new venue, show me the current funding rates across all perpetual exchanges — which one is cheapest for a short position and what's the total spread in bps?”
Technical details
Endpoint
GEThttps://api.usenami.io/v1/funding/spread/BTCWhen to prefer
Use this endpoint when you need an immediate, current cross-venue funding rate comparison for a specific symbol to identify arbitrage spreads or select the cheapest venue for a position. Prefer this over the historical rates endpoint when real-time spread is needed, and over the per-venue endpoint when you want the best/worst venue ranked automatically in a single call.
Side effects
- Symbol not supported — returns 404 or empty result for tickers not tracked by Nami
- Rate limit or payment failure — 402 response if x402 micropayment not completed
- Venue data temporarily unavailable — partial snapshot if one or more venues are offline
- Invalid symbol format — malformed ticker returns 400 error
- Stale data — snapshot may lag by a few seconds during high-volatility periods
