# Numora Bond Price Calculator

> Numora Bond Price Calculator is a paid API for AI agents from numormor.netlify.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Computes the present value (price) of a bond given yield-to-maturity, face value, coupon payment, and number of periods

## Facts

- Endpoint: POST https://numormor.netlify.app/api/financial/bond-price
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: 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-a181faed -d '<json body>'
```

Example prompt: What's the price of a bond with a face value of $1000, a coupon payment of $50, a yield-to-maturity of 6%, and 20 periods remaining?

## When to prefer this

Use this endpoint when you need a pure mathematical bond pricing computation with no external data dependencies — ideal when you already have all bond parameters (YTM, face, coupon, periods) and just need the present value calculated quickly and cheaply at $0.10 per call via micropayment.

## Known failure modes

- Missing required fields (ytm, face, coupon, periods) returns a 400-level error
- Non-integer periods value causes validation failure
- Negative or zero face value may produce nonsensical results
- Zero YTM causes division-by-zero or degenerate calculation
- Payment failure via x402 returns 402 status blocking the computation

## 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 price (present value of all future cash flows discounted at the given YTM), and a human-readable computation description string explaining what was calculated.
