# Numora Lease vs. Buy Comparison Calculator

> Numora Lease vs. Buy Comparison 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 a financial comparison between leasing and buying an asset, returning cost breakdowns and metrics for both scenarios

## Facts

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-lease-vs-buy-comparison-calculator-cffca060 -d '<json body>'
```

Example prompt: Compare leasing versus buying a $35,000 car — the lease is $450/month for 36 months with $2,000 down and a residual value of $18,000, while buying means a $5,000 down payment with a 5-year loan at 6.5% APR. Which comes out cheaper overall?

## When to prefer this

Use this endpoint when you need a pure mathematical comparison between lease and buy scenarios with no external data dependencies. Ideal for agents handling personal finance questions, car/equipment acquisition decisions, or any scenario where both lease terms and purchase loan terms are known and you need a deterministic cost analysis.

## Known failure modes

- Missing required buyParams or leaseParams objects returns a 400 validation error
- Malformed or incomplete nested parameters within buyParams/leaseParams may cause computation failure
- Payment not included or rejected results in a 402 Payment Required response
- Invalid numeric values (negative prices, zero terms) may cause undefined computation behavior

## 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 structured object containing the total cost of both the lease and buy scenarios, monthly payment breakdowns, any break-even or cost-difference metrics, and a human-readable description of what was computed.
