How this service works
Annualize a period funding rate (e.g. 8h → APR). Call when comparing funding across venues with different periods. Returns apr and periods_per_year as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
Output
Returns a JSON object with 'apr' (the annualized rate as a decimal or percentage) and 'periods_per_year' (how many funding periods occur in a year given the input hours), computed deterministically from local math with no external data dependencies.
Example use cases
Cross-venue funding rate comparison
“I'm seeing an 8-hour funding rate of 0.0025 on one exchange and a 1-hour funding rate of 0.0003 on another — can you annualize both so I can compare them apples-to-apples?”
Annual carry cost estimation
“My perp position is paying a 0.01% funding rate every 8 hours — what does that work out to as an annualized percentage so I can estimate my yearly carry cost?”
Funding arbitrage screening
“I have a 4-hour funding rate of 0.005 from one venue — annualize it to APR so I can decide if the funding income justifies the basis risk.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/funding-annualizeWhen to prefer
Use this endpoint when you need a fast, deterministic, server-side annualization of a periodic funding rate without any external data fetches or API keys — especially when comparing funding rates across venues that use different funding intervals (e.g. 1h vs 4h vs 8h). Prefer this over manual calculation when you want a consistent, auditable result for advisory or display purposes.
Side effects
- Missing required fields (hours or funding_rate) returns a validation error
- Non-positive or zero hours value may cause division errors
- Extremely large or small floating-point funding rates may produce unusual but mathematically correct APR values
- Payment failure via x402 protocol prevents execution
