## 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-financial-calculator-faff79d0 -d '<json body>'
```

Example prompt: What would my monthly payment be on a $250,000 loan at 6.5% annual interest over 30 years? Also tell me the total interest I'd pay over the life of the loan.

## When to prefer this

Use this endpoint when an agent needs precise, exact financial arithmetic for compound interest, loan/mortgage payment schedules, or ROI — especially in fintech, budgeting, or planning workflows where correct math matters. Prefer this over general-purpose code execution when you need a fast, cheap, structured response without spinning up a compute environment.

## Known failure modes

- Missing required fields for the selected calculation type return an error
- Non-numeric string values for numeric fields cause parsing failures
- Invalid calculation type string (not compound_interest, loan_payment, or roi) returns an error
- Division by zero scenarios (e.g. zero compounds_per_year) may return an error
- Negative or zero principal/rate may produce nonsensical results

## How this service works

Financial calculator API: compound interest (final amount, interest earned, effective annual rate), loan/mortgage payment (monthly payment, total paid, total interest), or ROI — from structured numeric inputs. For fintech, budgeting, and planning agents. Not financial advice; the arithmetic is exact.

## Output

Returns exact computed financial values depending on calculation type: for compound_interest — final amount, interest earned, and effective annual rate; for loan_payment — monthly payment, total paid, and total interest; for roi — return on investment percentage.
