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 success flag, a result object containing the computed bond yield (yield to maturity as a decimal or percentage), and a human-readable computation string describing what was calculated.
Example use cases
Discount bond yield analysis
“I have a corporate bond with a $1,000 face value selling at $920, paying $35 coupons per period over 20 periods — what's the yield to maturity?”
Premium bond return check
“A bond has a face value of $5,000, it's currently trading at $5,200, pays $150 in coupons each period, and matures in 8 periods. Can you calculate the yield for me?”
Zero-coupon bond effective yield
“What's the yield on a zero-coupon bond with a face value of $10,000, currently priced at $6,000, with no coupon payments, over 15 periods?”
Technical details
Endpoint
POSThttps://numormo.vercel.app/api/financial/bond-yieldWhen to prefer
Choose this endpoint when you need a pure mathematical computation of bond yield to maturity without relying on external market data feeds or financial APIs. Ideal for agents performing fixed-income analysis, portfolio valuation, or financial education tasks where the bond parameters are already known and a clean numeric result is needed. Best when operating in a zero-dependency environment with micropayment billing via x402 on Base.
Side effects
- Missing required fields (face, price, coupon, or periods) returns a validation error
- Negative or zero periods may produce a mathematical error or undefined result
- Price of zero causes division-by-zero or domain error
- Non-numeric inputs for numeric fields return schema validation failure
- Server-side computation error returns success: false with error details
