How this service works
100 pure math computation endpoints for AI agents. Statistics, financial math, linear algebra, equation solving, calculus, number theory, sequence generation, and unit conversions. Zero external dependencies. x402 micropayments on Base.
Output
Returns a success flag, a human-readable computation description, and a result object containing the amortization details — typically including the fixed monthly payment amount, a period-by-period schedule showing principal and interest portions, cumulative interest paid, and remaining balance for each payment period.
Example use cases
Monthly mortgage payment breakdown
“I'm buying a house and taking out a $400,000 mortgage at 7% annual interest for 30 years — can you calculate my monthly payment and show me the full amortization schedule?”
Car loan total interest cost
“I'm financing a $28,000 car at 5.9% interest over 60 months. How much will I end up paying in total interest by the end of the loan?”
Personal loan early payoff analysis
“I have a $15,000 personal loan at 9% annual interest with 48 months remaining. Can you give me the full amortization breakdown so I can see what my balance will be after 24 payments?”
Technical details
Endpoint
POSThttps://numomo.vercel.app/api/financial/loan-amortizationWhen to prefer
Choose this endpoint when you need a deterministic, pure-math amortization calculation with no external data dependencies, no rate lookups, and no side effects. Ideal for AI agents that already have the loan parameters and need a reliable, fast breakdown of payment schedules. Prefer over general-purpose LLM math when you need precision and a structured, machine-readable result. Use when the agent must handle financial calculations at scale via micropayment-gated API rather than a stateful financial platform.
Side effects
- Missing required fields (rate, months, principal) returns a validation error
- Negative or zero principal causes a computation error
- Zero or negative interest rate may produce unexpected results
- Non-integer months value rejected by schema validation
- Extremely large principal or rate values may cause numeric overflow
- Network timeout or Vercel cold-start latency on first call
- x402 payment failure if wallet has insufficient USDC balance
