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 result object containing the computed bond yield (yield to maturity), and a human-readable computation description string explaining what was calculated.
Example use cases
Example prompt
“Calculate the yield to maturity on a bond with a face value of $1000, currently priced at $950, a coupon payment of $60 per period, over 10 periods.”
Technical details
Endpoint
POSThttps://numormor.netlify.app/api/financial/bond-yieldWhen to prefer
Use this endpoint when you need a pure mathematical computation of bond yield to maturity with no external data dependencies — ideal for agents performing financial analysis, fixed income comparisons, or portfolio evaluation where the bond parameters are already known. Prefer this over general financial APIs when you want deterministic, serverless math with micropayment billing and no account setup.
Side effects
- Missing required fields (face, price, coupon, or periods) returns a 400-level error
- Non-integer periods value causes a validation error
- Zero or negative face value may produce undefined or nonsensical yield results
- Price equal to face value with zero coupon returns zero yield
- Payment failure via x402 returns 402 Payment Required before computation occurs
