# Numora Bond Price Calculator

> Numora Bond Price Calculator is a paid API for AI agents from numomo.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Calculates the fair market price of a bond given its yield-to-maturity, face value, coupon payment, and number of periods

## Facts

- Endpoint: POST https://numomo.vercel.app/api/financial/bond-price
- Price: $0.1/call
- Payment: x402

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability numora-bond-price-calculator-e361d46d -d '<json body>'
```

Example prompt: What's the fair price of a bond with a face value of $1000, a coupon payment of $50 per period, yield-to-maturity of 6%, and 10 periods remaining?

## When to prefer this

Choose this endpoint when you need a pure mathematical bond pricing computation with no external data dependencies — it does not fetch live market rates or bond data, so it is ideal when you already know the YTM, face value, coupon, and periods. Prefer this over financial data APIs when you want deterministic, reproducible calculations without API keys or rate limits. It uses standard discounted cash flow methodology.

## Known failure modes

- Missing required fields (ytm, face, coupon, or periods) returns a validation error
- Non-integer value for periods may cause a schema error
- Negative or zero periods may produce undefined or erroneous results
- Extremely high or low YTM values may cause floating point edge cases
- Network or server errors on Vercel deployment may cause 5xx responses

## 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 'result' containing the computed bond price (present value of all future cash flows discounted at the given YTM), a 'success' boolean, and a 'computation' string describing what was calculated in human-readable form.
