How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing the computed APR as a decimal, the input funding rate, the funding period in hours, and the number of such periods per year — e.g. {"apr": 0.1095, "hours": 8, "funding_rate": 0.0001, "periods_per_year": 1095}.
Example use cases
Perpetuals cost-of-carry comparison
“I'm holding a long BTC perp on three exchanges — each has a different funding rate and period length. Can you annualize each one so I can compare the real yearly cost? Start with 0.0001 every 8 hours.”
DeFi yield normalization
“A protocol is advertising a 0.0003 funding rate per 4-hour epoch. What does that actually work out to as an APR?”
Risk-adjusted position sizing
“I want to know how much a funding rate of 0.00005 every 1 hour would cost me annually before I decide how large a position to open on this perp.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/funding-annualize?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-use, no-signup computation of annualized funding rate from periodic rate data — especially useful for agents operating in crypto derivatives or DeFi contexts that need normalized APR figures for comparison, risk assessment, or position management. Prefer this over rolling your own formula when you need verifiable, consistent results with micro-payment billing via x402/USDC.
Side effects
- Missing required fields (hours or funding_rate) returns a 400 error
- Invalid types (e.g. string instead of integer for hours) cause schema validation errors
- Hours value of 0 would cause division-by-zero; likely returns an error
- Negative funding rates may be accepted but result in negative APR — verify interpretation
- Payment failure or insufficient USDC balance blocks the call via x402 protocol
