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 a boolean success flag, a human-readable computation description, and a result object containing the projected retirement balance or growth breakdown computed purely mathematically from the provided rate, years, savings, and contribution inputs.
Example use cases
Early retirement feasibility check
“I'm 35 with $60,000 saved, putting in $15,000 a year at a 6% annual return — can you calculate how much I'll have if I want to retire in 30 years?”
401k projection for financial plan
“Run the retirement math for me: $120,000 current balance, $18,000 annual contribution, 7.5% expected return, and 20 years until retirement.”
Low-savings catch-up scenario
“I'm starting late — only $10,000 saved, contributing $8,000 a year at 5% interest. How much will I have after 25 years?”
Technical details
Endpoint
POSThttps://numomo.vercel.app/api/financial/retirementWhen to prefer
Choose this endpoint when you need a fast, deterministic, pure-math retirement projection with no external data dependencies — ideal when you already have the interest rate, current savings, contribution amount, and time horizon and just need the compound growth math computed instantly without any market data lookups or account integrations.
Side effects
- Missing required fields (rate, years, savings, or contribution) returns a validation error
- Non-numeric values for rate or savings cause a 400 error
- Negative years or zero rate may produce unexpected mathematical output
- Network timeout if the Vercel serverless function is cold-starting
