World Stock Indices API

healthy 4,932 Subscribers

Live world stock-index levels as an API — the current level of the major stock-market indices, served from Yahoo Finance. For any index it returns the current level, the previous close, the absolute and percentage change on the day, the day's high and low, and the 52-week high and low, in the index's own currency. Look an index up by name or ticker alias (S&P 500, Nasdaq, Dow, FTSE 100, DAX, CAC 40, Euro Stoxx 50, Nikkei 225, Hang Seng, Sensex, ASX 200 and more), pull a regional board ranked by the day's move (US, Europe, Asia, Americas), or get the headline world board in a single call. The live index-quote layer for trading, markets and dashboard apps. Distinct from S&P 500 and Nasdaq constituent-directory APIs — this returns the live index level, not the member list.

Manifold API

Live prediction-market and forecaster data from Manifold, the largest play-money prediction market and forecasting community, via its public API. On Manifold anyone can create a market and everyone trades with mana, the platform's play-money, so each market's price is a crowd-sourced probability and every trader has a track record. Search markets and get each one's question, current probability, mana volume, unique-bettor count, liquidity and creator. Read one market in full, with its description and close time. See the top holders of a market — who is forecasting which way and how much mana they have invested. Read a forecaster's profile: their mana balance, all-time profit and how many markets they have created. Live, no key, nothing stored. Distinct from real-money prediction-market and sports-odds APIs — this is Manifold's community markets, their crowd probabilities and their forecasters. Perfect for forecasting, trading-signal, research and community apps.

Volatility Indices API

Live market "fear gauges" across asset classes as an API, served from Yahoo Finance. The VIX is the market's headline fear index — the S&P 500's 30-day implied volatility — and this returns it alongside the rest of the family: the 9-day VIX (short-term fear), the Nasdaq-100 (VXN) and Dow (VXD) volatility indices, crude-oil (OVX) and gold (GVZ) volatility, and the VVIX, the volatility of the VIX itself. Each comes with its current level, the day's change, and its day and 52-week range, and the board adds a plain-language fear regime from the VIX (complacent, normal, elevated, high or extreme). Get the whole board or one index. The implied-volatility and risk-sentiment layer for trading, macro-research and dashboard apps. Live, no key, no cache. Distinct from equity-index, crypto-volatility and FX-volatility APIs — this is the cross-asset implied-volatility (fear) suite.

Stock Sectors API

Live S&P 500 sector performance as an API — the sector-rotation picture traders watch, served from Yahoo Finance via the eleven SPDR sector ETFs. It returns each of the eleven GICS sectors — Technology, Financials, Energy, Health Care, Consumer Discretionary, Consumer Staples, Industrials, Materials, Utilities, Real Estate and Communication Services — with its tracking ETF's price, the day's change, the day's high and low, and the 52-week high and low. Pull the whole board ranked by the day's move, with the leading and lagging sectors called out, or look one sector up by name or ETF ticker. The sector-rotation and market-breadth layer for trading, macro-research and dashboard apps. Live, no key, no cache. Distinct from index-level, single-stock and cross-asset-ratio APIs — this is the equity-sector performance breakdown.

Stock Dividends API

Live stock dividend data as an API — the dividends any listed stock or ETF actually pays, served from Yahoo Finance. For any ticker it returns the trailing-twelve-month dividend per share, the current dividend yield, the payment frequency (monthly, quarterly, semi-annual or annual), the most recent payment with its date, and the dividend payment history. Look a stock up by ticker or company name, or pull its full payment history over several years. Non-paying stocks are reported cleanly with a zero yield so you can screen for income. The dividend-income layer for investing, screening and dashboard apps. Live, no key, no cache. Distinct from dividend-ratio calculators and from price-quote APIs — this returns the stock's actual dividends paid and its real yield.
