Option Strategy API

healthy 3,136 Subscribers

Live options-strategy payoff and analysis that options traders run before placing a trade — computed on demand, no key, nothing cached. Get the profit-at-expiry curve of any multi-leg position (calls, puts and stock) plus the net premium, maximum profit, maximum loss and breakeven points; pull just those headline numbers; or build a named strategy (straddle, strangle, bull/bear spread, covered call, protective put, iron condor) from friendly parameters and analyse it. Works for equity, FX or crypto options. A multi-leg payoff engine, distinct from single-option pricing tools: it turns a combination of legs into the profit profile, breakevens and risk a trader acts on.

Crypto Volatility API

Live crypto realized (historical) volatility as an API, computed from Binance daily candles. For any coin it returns the annualized realized volatility over the 7-, 30- and 90-day windows — the standard deviation of daily log returns, annualized over 365 days — the average true range as a percent of price, the current price, and a plain-language regime label (low, normal, high or extreme). It can also rank a basket of major coins by their 30-day volatility, so you can see at a glance which assets are calm and which are wild. The volatility layer that options pricing, position sizing and risk dashboards need. Live, no key, no cache. Distinct from price, OHLC and drawdown APIs — this is the realized-volatility analytic.

Crypto Options API

Live crypto options-market data as an API, streamed from the Deribit public exchange. For BTC, ETH, SOL and XRP: the full option chain with each contract's mark price, mark implied volatility, open interest, 24-hour volume and underlying price; the nearest at-the-money call and put for a one-call read on how the market prices risk; the spot index price; the historical realised-volatility series with stats; and a market-wide summary of open interest, volume and expiries. Built for options, volatility, quant and trading apps. Distinct from spot-price, funding and on-chain APIs — this is the live options surface.

Black-Scholes Options API

Black-Scholes-Merton European option pricing as an API, computed locally and deterministically. The price endpoint computes the fair value of a European call and put from the spot price, strike, annualized risk-free rate, annualized volatility, time to expiry in years and an optional continuous dividend yield, using Call = S·e^(−qT)·N(d1) − K·e^(−rT)·N(d2) and the put-call-parity put, with d1 = [ln(S/K) + (r − q + σ²/2)·T]/(σ√T) and d2 = d1 − σ√T and a high-accuracy standard-normal CDF — an at-the-money option on a 100 spot with a 5 % rate, 20 % volatility and one year to expiry is worth about 10.45 for the call and 5.57 for the put. The greeks endpoint returns the full risk sensitivities for both call and put: delta (∂V/∂S), gamma (∂²V/∂S²), vega (∂V/∂σ, per 1.00 and per 1 % point), theta (∂V/∂t, per year and per calendar day) and rho (∂V/∂r). Rates, dividend yield and volatility are annualized and time is in years, continuous compounding. Everything is computed locally and deterministically, so it is instant and private. Ideal for fintech, trading, quant, portfolio-risk, derivatives and finance-education app developers, option-pricing and Greeks dashboards, and risk engines. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 2 endpoints. This is the European Black-Scholes model; for American-style early exercise or implied volatility solving it returns the closed-form European result only.

Options Pricing API

Black-Scholes option-pricing maths as an API, computed locally and deterministically. The black-scholes endpoint prices European call and put options from the spot price, strike, time to expiry, risk-free rate, volatility and an optional dividend yield — Call = S·e^(−qT)·Φ(d1) − K·e^(−rT)·Φ(d2) — returning both prices, the intermediate d1 and d2, and the put-call parity figure. The greeks endpoint computes the full set of option sensitivities for the call and the put: delta, gamma, theta (per year and per day), vega and rho, the quantities traders use to hedge and manage risk. The implied-volatility endpoint inverts the model, solving by bisection for the volatility that reproduces a given option market price. Rates, volatilities and dividend yields are decimals (0.05 = 5 %) and time to expiry is in years. Everything is computed locally and deterministically, so it is instant and private. Ideal for fintech, trading, quantitative-finance and derivatives app developers, options analytics and risk tools, and finance education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is options pricing; for NPV and IRR use an NPV API and for CAGR and real returns an investment API.
