How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

Output

Returns a JSON object with ok:true and paid:true along with the computed compound interest result, including total accumulated value and interest earned based on the provided principal, rate, frequency, and duration.

Example use cases

Savings account growth projection

“I have $5,000 in savings at a 4.5% annual interest rate compounded monthly — how much will I have after 10 years?”

Loan total cost estimation

“Calculate the total amount I'd owe on a $20,000 loan at 6% annual interest compounded quarterly over 5 years.”

Investment portfolio compounding return

“If I invest $15,000 at an 8% annual return compounded annually for 20 years, what will my total be and how much is purely from compound interest?”

When to prefer

Choose this endpoint when you need a fast, deterministic, no-signup compound interest computation accessible to AI agents via micro-payment on Base. Ideal when no API key management is desired and the agent can autonomously handle x402 USDC payments on Base.

Side effects

Missing or malformed schema parameter returns an error
Invalid numeric values for rate or principal cause computation failure
Payment not fulfilled returns 402 Payment Required
Negative time period or zero principal yields degenerate results
