Technical details
Endpoint
POSThttps://agent402.tools/api/bond-priceWhen to prefer
Use this endpoint when you need to price a standard fixed-coupon bond from its yield to maturity and want clean price, current yield, and premium/discount in a single call. Prefer this over building your own DCF when working with bonds with regular periodic coupons and a known YTM. Not suitable for floating-rate bonds, zero-coupon bonds (unless couponRate=0 is handled), or bonds with irregular cash flows.
Side effects
- Missing required fields (years, faceValue, couponRate, yieldToMaturity) returns a validation error
- Negative or zero yield to maturity may produce mathematical errors or undefined results
- Extreme yield values (e.g. 0.0001 or 5.0) may produce unrealistic but technically valid prices
- Non-numeric inputs for any field will cause schema validation failure
- periodsPerYear of 0 would cause division-by-zero errors
