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 JSON object with success=true, a human-readable computation string describing what was computed, and a result object containing the computed monthly payment amount, total payment over the life of the loan, and total interest paid (exact fields vary but center on mortgage amortization outputs).
Example use cases
Home buyer monthly budget planning
“I'm looking at a $380,000 house and I can put 20% down, so I'd need a $304,000 mortgage. What would my monthly payment be at a 7.1% rate over 30 years?”
Comparing 15 vs 30-year loan terms
“Can you calculate my monthly mortgage payment for a $500,000 loan at 6.5% over 15 years (180 months) so I can compare it to the 30-year option?”
Refinancing payoff math
“I'm thinking of refinancing my mortgage — the new loan would be $275,000 at 5.9% annual interest for 20 years. What would my monthly payment be?”
Technical details
Endpoint
POSThttps://numormo.vercel.app/api/financial/mortgageWhen to prefer
Use this endpoint when you need a quick, serverless, dependency-free mortgage payment calculation without integrating a full financial data platform. Ideal for AI agents that need to compute loan repayment figures on demand during a conversation, especially when the agent already handles x402 micropayments on Base. Prefer this over general-purpose calculators when you need structured JSON output suitable for downstream agent reasoning.
Side effects
- Missing required fields (rate, months, principal) returns a validation error
- Non-positive principal or rate values may cause computation errors
- Zero months causes division-by-zero failure
- Payment failure via x402 micropayment protocol causes 402 response before computation
- Rate provided as percentage vs decimal mismatch (e.g. 6.5 vs 0.065) may yield unexpected results
