## 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 forgemesh-loan-payment-calculator-915600b7 -d '<json body>'
```

Example prompt: What would my monthly payment be on a $15,000 personal loan at 7.5% annual interest over 4 years, compounded monthly? Run a loan_payment calculation for me.

## When to prefer this

Use this endpoint when an agent needs deterministic, citable financial math without building the formulas itself — especially for loan payment planning, compound interest projections, or ROI comparisons. Prefer this over LLM-generated math when accuracy and reproducibility are critical for budgeting or financing decisions.

## Known failure modes

- Missing required fields for the selected calculation type returns an error or null result
- Invalid non-numeric strings passed for numeric fields may cause computation failure
- Unsupported calculation type string outside 'compound_interest | loan_payment | roi' returns an error
- Zero or negative rate/term values may produce nonsensical or undefined results

## How this service works

Loan payment calculator covering compound interest growth, monthly installment amounts, and return-on-investment math from plain numeric inputs — principal, rate, term, contribution. Useful for budgeting tools, debt payoff planning, and comparing financing offers side by side. Deterministic results an agent can cite without re-running the math itself.

## Output

Returns a deterministic numeric result for the requested financial calculation — either the monthly installment amount for a loan, the total compound interest accrued over a term, or the return on investment — based on the supplied principal, rate, term, and compounding frequency.
