Stock Market Fear & Greed Index API

healthy 4,407 Subscribers

Live CNN Fear & Greed Index for the US stock market — no key, nothing stored. The equity-market sentiment gauge: a single 0–100 score (0 = extreme fear, 100 = extreme greed) built from seven market indicators, distinct from the crypto Fear & Greed index in the catalogue. The index endpoint returns the headline score and rating plus the previous close and the readings one week, one month and one year ago, so you can see how sentiment has shifted. The components endpoint breaks the index into its seven underlying indicators — market momentum, stock-price strength, stock-price breadth, put/call options, market volatility (VIX), junk-bond demand and safe-haven demand — each with its own score and fear/greed rating, so you can see what is actually driving sentiment. The history endpoint returns the daily score timeline for the last year. Build market-sentiment dashboards, contrarian-signal bots, risk dashboards and newsletter widgets on top of the most-watched sentiment gauge in equities. Score bands: 0–24 extreme fear, 25–44 fear, 45–55 neutral, 56–75 greed, 76–100 extreme greed.

Crypto Volume Profile (VPVR) API

Where a crypto pair has actually traded the most volume by price level, computed live from Binance candles — no key, nothing stored. Most charts show volume over time; the volume profile shows it over price, and that is where support and resistance really live. The profile endpoint splits the price range into buckets and distributes each candle's volume across the prices it spanned, returning the volume-by-price histogram, the Point of Control (POC — the single price with the most traded volume, the market's fair-value magnet), the Value Area (the price band holding roughly 70% of all volume) with its high (VAH) and low (VAL), and the high-volume nodes. The levels endpoint returns just those key levels plus where the current price sits relative to the value area — above it (acceptance higher), inside it, or below — the read traders use for mean-reversion and breakout setups. The symbols endpoint lists tradable pairs. This is the volume-by-price / market-profile cut for crypto — distinct from the raw OHLCV candle feed, the time-of-day seasonality API, the trade-size distribution and the order-flow APIs in the catalogue. Pairs are Binance symbols (BTCUSDT) or a coin=BTC&quote=USDT form; interval is 15m/1h/4h/1d.

Crypto Intraday & Seasonality API

The time-of-day and day-of-week patterns hiding in a crypto pair's price history, computed live from Binance candles — no key, nothing stored. Crypto trades 24/7, but it does not trade evenly: some hours (the US equity open, the Asia session) carry far more volume and volatility than others, and some weekdays run hotter than weekends. The hourly endpoint buckets recent hourly candles by UTC hour of day and returns, for each of the 24 hours, the average return, the average volume, the average high-low range (a volatility proxy) and the up-rate (how often that hour closed green) — plus the most volatile and most bullish hours. The dayofweek endpoint does the same across the seven weekdays from daily candles, with the best and worst day. The symbols endpoint lists tradable pairs. This is the intraday / seasonality pattern cut for crypto — distinct from the raw OHLCV candle feed, the realised-volatility API and the FX-seasonality (calendar-month) API in the catalogue. It tells you WHEN a market tends to move, not just how much. Patterns are descriptive, not predictive. Pairs are Binance symbols (BTCUSDT) or a coin=BTC&quote=USDT form; all times are UTC.

Crypto Trade Size Distribution API

Who is actually trading a pair — retail or whales — read from the composition of Binance's aggregated trade tape by trade size, no key, nothing stored. Order flow tells you the net direction; this tells you the size profile behind it: whether a move is driven by a swarm of small retail prints or a handful of large institutional ones, often the more important signal. The distribution endpoint scans the recent aggregated trades for a pair and buckets them into size cohorts (micro under $1k, retail $1k-$10k, mid $10k-$100k, whale over $100k), returning each cohort's trade count, volume in base and quote and its share of total volume, plus the whale-volume share — the single read on how institutional the flow is. The percentiles endpoint returns the trade-size percentiles (p50, p90, p99) and the average, median and largest trade. The symbols endpoint lists tradable pairs. This is the trade-size composition / participant-mix analytics cut for crypto — distinct from the order-flow / CVD API (which measures buy-versus-sell direction), the order-book depth, the slippage and the price APIs in the catalogue. Pairs are Binance symbols (BTCUSDT) or a coin=BTC&quote=USDT form.

Crypto Correlation & Beta API

How crypto assets move together, computed live from Binance daily candles — no key, nothing stored. Correlation is the single most important input to diversification, pairs trading and risk: two coins with a correlation near 1 are effectively the same bet, while a low or negative correlation is genuine diversification. The matrix endpoint returns the full pairwise return-correlation matrix across a basket of coins over a chosen window, together with the average pairwise correlation — a one-number gauge of how "risk-on, all-together" the market is. The pair endpoint returns the correlation between any two coins, with the R-squared and a plain-language relationship label. The beta endpoint returns each coin's beta to BTC — how much it amplifies (beta above 1) or dampens (beta below 1) Bitcoin's moves — with its correlation and R-squared, the read altcoin traders use to size directional bets. Everything is computed from the standard deviation and covariance of daily log returns. This is the cross-asset correlation / beta analytics cut for crypto — distinct from the FX-correlation API, the single-asset realised-volatility API and the portfolio-optimiser in the catalogue. Coins are Binance bases (BTC, ETH) or full symbols (BTCUSDT); the quote defaults to USDT and the window is 14-365 days.
