How this service works
A curated directory of x402 services — each one on the list on purpose, with the health, uptime, and independent trust grades from across the ecosystem gathered in one place.
Output
Returns a JSON object with the input APR as a percentage, the computed APY as a percentage (accounting for compounding), and a projected end-value given the principal — e.g. {"apr_pct": 12, "apy_pct": 12.68, "projected_value": 1126.83}.
Example use cases
DeFi yield comparison for staking
“I'm looking at a staking pool offering 18% APR — what's the actual APY I'd be earning, and what would $5,000 grow to over a year?”
Savings account effective yield check
“My bank advertises a savings account at 4.5% APR. Can you tell me what the real APY is and how much $10,000 would become after 12 months?”
Crypto lending rate evaluation
“A lending protocol is offering 9.75% APR on USDC deposits. What does that work out to in APY terms and what's the projected value on a $2,500 deposit?”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/apr-apy-converterWhen to prefer
Use this endpoint whenever you need to accurately translate a nominal APR into its effective APY equivalent, especially in financial, DeFi, or savings contexts where compounding matters. Prefer this over manual calculation when you also need a projected end-value for a given principal, saving multiple computation steps in one call.
Side effects
- Missing or invalid APR input returns an error
- Negative interest rate values may produce unexpected results
- Very large or very small compounding frequencies could cause computation edge cases
- Non-numeric principal values will likely return a validation error
