# Numora Depreciation Calculator

> Numora Depreciation 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 asset depreciation schedules using straight-line, declining balance, or sum-of-years-digits methods given cost, useful life, and salvage value

## Facts

- Endpoint: POST https://numormo.vercel.app/api/financial/depreciation
- 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-depreciation-calculator-717d55e0 -d '<json body>'
```

Example prompt: Calculate the depreciation schedule for a piece of equipment that cost $50,000, has a useful life of 7 years, a salvage value of $5,000, using the straight-line method.

## When to prefer this

Choose this endpoint when you need precise, auditable depreciation schedules for accounting, tax, or financial reporting purposes and require support for multiple standard methods (straight-line, declining balance, sum-of-years-digits) without setting up your own math library. Ideal for AI agents handling financial planning, asset tracking, or automated bookkeeping workflows that need zero-dependency, pure-math computation via micropayment.

## Known failure modes

- Missing required fields (cost, life, salvage) returns a validation error
- life must be a positive integer; non-integer or zero values may cause errors
- salvage value greater than cost may produce nonsensical results
- Invalid method enum value returns an error; only 'straight-line', 'declining', 'sum-of-years' are accepted
- Payment failure (insufficient USDC balance) blocks the request via x402 protocol

## 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 success flag, a human-readable computation description, and a result object containing the year-by-year depreciation amounts, accumulated depreciation, and ending book value for each period of the asset's useful life, computed under the chosen depreciation method.
