# Numora Bond Price Calculator

> Numora Bond Price Calculator is a paid API for AI agents from numorapoi.orbonomy.xyz, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

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

## Facts

- Endpoint: POST https://numorapoi.orbonomy.xyz/api/financial/bond-price
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/numora-bond-price-calculator-9158b60e

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-9158b60e -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you need a pure serverless math computation for bond pricing with no external data dependencies — ideal when you already have the bond parameters (ytm, face, coupon, periods) and need a precise present-value calculation without fetching live market data. Prefer this over financial data APIs when the inputs are known and you just need the math.

## Known failure modes

- Missing required fields (ytm, face, coupon, periods) returns validation error
- Non-numeric input for numeric fields causes 400 error
- Negative periods or zero face value may cause computation error
- Payment failure via x402 returns 402 status before computation
- Server unavailable at orbonomy.xyz domain returns 503

## How this service works

## Output

Returns a JSON object with a success flag, a result object containing the computed bond price, and a human-readable computation description explaining what was calculated.
