#valuation

Stock dividend and valuation fundamentals as an API, computed locally and deterministically — the per-share ratios value and income investors screen on. The dividend endpoint takes a share price and an annual dividend (per share, or total dividends ÷ shares) and returns the dividend yield, and with earnings per share the payout ratio (dividend ÷ EPS), the dividend coverage (EPS ÷ dividend) and the retention ratio — a $2 dividend on a $50 share yields 4 %, and on $4 EPS is a 50 % payout covered twice. The valuation endpoint computes the price-to-earnings ratio, earnings yield, the PEG ratio against a growth rate, the price-to-book ratio and the Graham number √(22.5 · EPS · book value) — Benjamin Graham's rough fair-value ceiling. The ddm endpoint runs the Gordon Growth dividend discount model, fair value = D1 ÷ (r − g) from next year's dividend, the required return and the perpetual growth rate, and against a market price flags whether the share looks under- or over-valued and the implied cost of equity. Everything is computed locally and deterministically, so it is instant and private. Ideal for investing, brokerage, robo-advisor, dividend-screener and fintech app developers, stock-valuation and income-portfolio tools, and finance education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. These are valuation ratios from your inputs; for live quotes use a market-data API and for project DCF/NPV an investment-appraisal API.
