## 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 investing-math-dividend-yield-income-calculator-0e64760a
```

Example prompt: I own 200 shares of a stock priced at $75 with an annual dividend of $3 per share and a 4% annual dividend growth rate — can you calculate the dividend yield, my yearly and monthly income, and project what my cumulative dividends and yield on cost will look like after 15 years?

## When to prefer this

Use this endpoint when you need to compute dividend-specific investing metrics — yield, income projections, yield on cost, and cumulative dividend totals — especially with a dividend growth rate component. Prefer it over generic financial calculators when the user is evaluating income-generating dividend stocks or planning long-term passive income from equity holdings.

## Known failure modes

- Missing required fields (price or annualDividend) returns a validation error
- Years outside 1–60 range may be rejected or clamped
- Negative price or dividend values may produce nonsensical results
- Zero price causes division-by-zero for yield calculation
- Network/payment failure returns HTTP 402 or 5xx error

## How this service works

Dividend yield, yearly income, and yield on cost and total dividends after years of dividend growth.

## Output

Returns dividend yield percentage, annual and monthly income, total position value, yield on cost percentage, the projected dividend per share after N years of growth, and cumulative dividends collected over the projection period. Also includes growth rate used and optional disclaimers.
