# Numora Bond Price Calculator

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

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

## Facts

- Endpoint: POST https://numormo.vercel.app/api/financial/bond-price
- Price: $0.1/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-87ba0fd5

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-87ba0fd5 -d '<json body>'
```

Example prompt: Calculate the price of a bond with a face value of $1000, a coupon payment of $50 per period, a yield to maturity of 6%, and 10 periods remaining.

## When to prefer this

Choose this endpoint when you need a serverless, dependency-free bond pricing computation without integrating a full financial data platform. Ideal for AI agents that need real-time bond valuation as part of a larger workflow, portfolio analysis pipelines, or educational tools where no Bloomberg/Reuters connectivity is available. Particularly suited for scenarios where you supply all bond parameters yourself and need a pure mathematical result fast.

## Known failure modes

- Missing required fields (ytm, face, coupon, periods) returns a validation error
- Non-integer periods value causes schema rejection
- Negative or zero YTM may produce mathematically undefined or extreme results
- Zero face value or coupon may return trivially zero prices
- Network timeout on Vercel cold start
- Micropayment failure via x402 protocol blocks the request

## 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.
