Live data from the Taiwan Stock Exchange (TWSE), with no key. Read the daily quote for any listed stock by its code (open/high/low/close, change, traded volume and value); pull a whole-market snapshot of every listed stock; get per-stock valuation metrics (price/earnings ratio, price/book ratio and dividend yield); read the live value of every TWSE index (the headline TAIEX and all sector indices); and get the daily history of the TAIEX index. The Taiwan-equities / valuation / index layer for trading dashboards, screeners and fintech — distinct from other exchange readers, with a dedicated valuation cut. Live from TWSE via its official OpenAPI; short cache only.

The Bitcoin cycle-timing valuation models that tell you whether BTC is historically cheap or expensive right now, computed live and keyless from price (Yahoo Finance daily closes) and on-chain data (the public blockchain.com charts feed). These are not raw time series and not a price feed — they are the derived indicators that on-chain analysts and cycle traders watch to judge where Bitcoin sits between deep value and euphoria. The mayer endpoint returns the Mayer Multiple — price divided by its 200-day moving average — the simplest and most durable over/undervaluation gauge (buying under ~1 and trimming over ~2.4 has historically timed cycles well). The puell endpoint returns the Puell Multiple — daily miner revenue divided by its 365-day average — a miner-side gauge that marks capitulation bottoms (under ~0.5) and tops (over ~4). The nvt endpoint returns the NVT ratio — market cap divided by the 90-day average of on-chain transaction value — Bitcoin's answer to a price/earnings ratio, where a high reading means price is rich relative to the value actually settling on-chain. The s2f endpoint returns the Stock-to-Flow scarcity ratio — circulating supply divided by the realised annual issuance (the flow measured empirically from the supply actually minted over the last 365 days); the S2F price model derived from it is included but clearly flagged as controversial and historically over-optimistic (the response also reports how far the model sits above the actual price). The summary endpoint puts all four side by side with an aggregate cycle read. This is the valuation-model / cycle-indicator cut — distinct from the raw Bitcoin on-chain time-series feeds (which report hashrate, miner revenue and transaction counts but not the derived ratios), the network-security feed (difficulty, hashrate, halving), the block-explorer feed and the crypto-macro correlation feed. Ratios are unitless; model and actual prices are in USD. No key, nothing stored beyond a short cache.

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.
