How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
Returns a JSON object with 'interest' (the raw interest accrued), 'total' (principal plus interest), and a 'notice' disclaimer clarifying the result is a mathematical calculation from supplied inputs only, not financial advice.
Example use cases
Loan repayment estimation for borrower
“I'm borrowing $25,000 at a 6.5% annual interest rate for 5 years — can you calculate the total simple interest I'll owe and what my total repayment will be?”
Savings interest projection for investor
“If I put $100,000 into a fixed-deposit account at 4.2% annual interest for 2 years, how much simple interest will I earn and what will the total be?”
Quick rate comparison for financial planning
“Help me compare two scenarios: $50,000 at 3% for 10 years versus $50,000 at 7% for 4 years — compute the simple interest and total for each.”
Technical details
Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/finance/simple-interest?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic simple-interest computation (P×R×T) from explicitly supplied inputs, without needing compound interest, amortization schedules, or live market rate lookups. Ideal for quick loan estimation, savings projections, or any scenario where the agent supplies all three inputs directly.
Side effects
- Missing required fields (principal, annual_rate_percent, years) may return a validation error
- Values exceeding schema maximums (e.g. principal > 1 trillion, rate > 1000%) will be rejected
- Floating-point precision edge cases may yield minor rounding differences
- Payment failure (x402) will block access if USDC balance is insufficient
