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.

Currency Correlation API
A live forex correlation analytic as an API, computed from European Central Bank daily reference rates. It measures how the world's currencies move together: each currency's daily appreciation is correlated against every other, so you can see which currencies move in lock-step (don't double up the same risk) and which move opposite (natural hedges). Get one currency's correlations to all others ranked, the coefficient for any pair, or a full correlation matrix for a basket. Risk and diversification input for forex, portfolio and trading apps. Live, no key. Distinct from currency-strength (direction) and FX-volatility (magnitude) — this is co-movement.

Statistics Calculator API
Descriptive-statistics maths as an API, computed locally and deterministically. The descriptive endpoint summarises a list of numbers — the count, sum, mean, median, mode, minimum, maximum and range, the population and sample variance and standard deviation, and the quartiles Q1/Q2/Q3 with the interquartile range by Tukey's method. The correlation endpoint computes the Pearson correlation coefficient r between two equal-length series — from −1 (perfect inverse) through 0 (none) to +1 (perfect direct) — along with R² and the covariance. The regression endpoint fits a least-squares line y = a + b·x, returning the slope, intercept and R², the equation, and an optional prediction for a given x. Data is accepted as a JSON array or a comma-separated list. Everything is computed locally and deterministically, so it is instant and private. Ideal for data-analysis, dashboard, research and education app developers, reporting and BI tools, and spreadsheet replacements. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is descriptive statistics; for probability distributions and combinatorics use a probability API.

CAPM & Beta API
Live capital-asset-pricing-model and systematic-risk analytics that quants and portfolio managers run on an asset against a market benchmark, computed on demand from the two series you pass in — no key, no cache, nothing stored. The beta endpoint regresses an asset's returns on the market's and returns the beta, the alpha (per period and annualised), the correlation and the R-squared, so you see how strongly the asset tracks the market and how much it amplifies it. The capm endpoint returns the CAPM expected return — risk-free rate plus beta times the market risk premium — and Jensen's alpha, the excess over what beta says the asset should earn; it also has a direct mode where you pass beta, market return and risk-free rate with no series. The treynor endpoint returns the Treynor ratio, the reward per unit of systematic (market) risk. This measures risk relative to a market — systematic risk — which is fundamentally different from single-series total-risk tools: it needs two series and answers how an asset moves with, and is priced against, the market. Works for any asset against any benchmark: stocks, funds, crypto, FX or a whole portfolio. Computed locally and deterministically, so it is instant and private. Ideal for portfolio analytics, factor and risk dashboards, fund fact-sheets and back-tests. Rates are fractions (0.02 = 2%). Live, nothing stored. 3 compute endpoints. For single-series Sharpe/volatility/drawdown use a risk-metrics API.

Crypto Funding Rate Arbitrage API
The perpetual-futures funding rate for a coin side by side across the major exchanges, and the spread between them — computed live from each venue's public API, no key, nothing stored. A perpetual swap charges or pays funding every few hours to keep its price tethered to spot; when the same coin's funding differs across exchanges, a trader can be long the perp where funding is most negative (and gets paid) and short where it is most positive, harvesting the spread market-neutral. The funding endpoint returns, for a coin, the current funding rate on Binance, Bybit, OKX and Gate.io — per interval and annualised — the venue paying the most, the one charging the most, and the cross-exchange spread (the arbitrage edge). The screener endpoint scans a basket and ranks the coins by the size of that spread, surfacing the biggest funding-arbitrage opportunities. This is the cross-exchange funding-rate / basis-arbitrage cut for crypto — distinct from the single-exchange funding-rates feed (one venue), the spot-versus-perpetual basis and the price APIs in the catalogue. Funding is per interval (most venues settle every 8 hours); annualisation assumes three settlements a day, and intervals can differ by venue, so verify before trading. Coins are bases (BTC, ETH).
