How this service works
Per-venue funding carry for one crypto perpetual: raw funding_rate, annualized_carry_pct, and contango/backwardation structure from the funding sign. What holding this perp pays or costs you per year, venue by venue, across tracked CEX and DEX venues.
Output
Returns the raw funding rate for the requested ticker/venue, the annualized carry percentage derived from it, and a contango/backwardation classification inferred from the sign of the funding rate — allowing agents to assess carry trade attractiveness and market structure at a glance.
Example use cases
Carry trade opportunity scanner
“Check the annualized carry percentage for ETH perpetual futures across all venues — I want to know which exchange is offering the best carry and whether the market is in contango or backwardation.”
Funding rate arbitrage monitoring
“Pull the current funding rate and annualized carry for SOL perps on Bybit — I'm running a delta-neutral funding arbitrage strategy and need to know if it's worth opening a position.”
Market sentiment signal from funding
“What's the funding sign structure for BTC perps right now? I want to understand if the market is leaning bullish or bearish based on whether it's in contango or backwardation.”
Technical details
Endpoint
GEThttps://api.usenami.io/v1/perp/carryWhen to prefer
Use this endpoint when you need fast, structured per-venue funding carry data including the annualized carry percentage and contango/backwardation label — especially for carry trade analysis, delta-neutral strategy setup, or market sentiment signals derived from funding sign. Prefer this over a raw exchange API when you want normalized, pre-computed carry metrics across venues without building your own annualization logic.
Side effects
- Unknown ticker symbol returns an error or empty result
- Unsupported venue returns no data
- Missing required input fields (type or method) returns a validation error
- Stale funding data if the exchange feed is delayed
- Rate limit exceeded if too many calls are made in quick succession
