Live on-chain data for Carbon (chain id carbon-1) — the Switcheo-built Cosmos-SDK Layer-1 for decentralised derivatives and spot trading, whose native token is SWTH — served directly from public LCD/REST nodes with multi-node failover. The status endpoint returns the latest block height and time, chain id, the staking bond denom and the current minting inflation rate. The validators endpoint lists the active bonded validator set ranked by stake, each with its moniker, operator address, self-plus-delegated SWTH, commission rate and jailed flag. The supply endpoint returns the total SWTH supply, the amount bonded in staking and the resulting bonded ratio. The governance endpoint returns the most recent on-chain proposals with their id, title, status and voting window. SWTH uses an 8-decimal base denomination which is converted to whole SWTH with exact big-integer scaling, and every figure is read live from the chain — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for staking dashboards, validator and delegator tooling, explorers, governance trackers and portfolio or analytics apps across the Cosmos and DeFi ecosystem. Live keyless upstream. 5 endpoints.

Ein börsenübergreifender Aggregator für Kryptowährungs-Perpetual-Futures- und Derivate-Märkte – die Funding Rates, Open Interest und Volumen, die den gehebelten Krypto-Handel antreiben, zusammengefasst über alle gelisteten Derivatebörsen (Binance, Bybit, OKX, Hyperliquid, MEXC und Dutzende weitere). Der Perps-Endpunkt ordnet die größten Perpetual-Märkte nach Open Interest mit ihrem Preis, Funding Rate, Open Interest und 24h-Volumen. Der Funding-Endpunkt vergleicht die Funding Rate eines Assets (z.B. BTC, ETH, SOL) über jede Börse, die es listet, mit dem Durchschnitt – so können Sie Funding-Dislokationen und Basis-Trades auf einen Blick erkennen. Der Exchanges-Endpunkt ordnet Derivatebörsen nach Open Interest mit ihren Perpetual- und Futures-Paar-Anzahlen. Der Overview-Endpunkt aggregiert das gesamte Open Interest, das gesamte 24h-Volumen und die Anzahl der Perpetual-Paare über den gesamten Derivate-Markt. Der Meta-Endpunkt dokumentiert die API. Live aggregierte Daten, leicht gecached; Funding Rates sind Prozentsätze, Open Interest in USD pro Markt und BTC für Börsen-Gesamtsummen. Live. 5 Endpunkte. Dies aggregiert Derivate über alle Börsen; für das rohe Orderbuch einer einzelnen Börse verwenden Sie die API dieser Börse.

How crypto's biggest, most-capitalised futures traders are positioned versus the retail crowd — and the divergence between them — computed live from Binance's public futures positioning feed (no key, nothing stored). Binance splits its perpetual traders into the whole crowd and the "top traders" (the top ~20% of accounts by margin balance, a smart-money proxy) and publishes the long/short split of each. When smart money leans one way while the crowd leans the other, that gap is a classic contrarian signal: an over-long retail crowd the big accounts are quietly fading often marks a local top, and vice versa. The positioning endpoint returns, for a coin, the long/short ratio and long-share of three cohorts side by side — the global crowd, the top traders by account, and the top traders by position size. The divergence endpoint returns the smart-money-minus-retail gap with a plain-language read. The history endpoint returns the time-series across 5m to 1d buckets so you can watch the gap open and close. The smart-money-versus-retail / positioning-divergence cut for crypto — distinct from the single-cohort long/short-ratio feed, the funding-rate, open-interest and price APIs. It tells you who is on which side, not just how many are long.

Die perpetual-futures Funding Rate für einen Coin nebeneinander auf den großen Börsen und der Spread zwischen ihnen – live berechnet aus den öffentlichen APIs jeder Plattform, kein API-Key, nichts gespeichert. Ein Perpetual-Swap berechnet oder zahlt alle paar Stunden Funding, um seinen Preis an den Spotpreis zu binden; wenn sich das Funding desselben Coins zwischen den Börsen unterscheidet, kann ein Trader den Perp long gehen, wo das Funding am negativsten ist (und er bezahlt wird), und short gehen, wo es am positivsten ist, und so den Spread marktneutral ernten. Der Funding-Endpunkt gibt für einen Coin die aktuelle Funding Rate auf Binance, Bybit, OKX und Gate.io zurück – pro Intervall und annualisiert – die Börse, die am meisten zahlt, die, die am meisten verlangt, und den börsenübergreifenden Spread (die Arbitrage-Marge). Der Screener-Endpunkt durchsucht einen Korb und ordnet die Coins nach der Größe dieses Spreads und zeigt die größten Funding-Arbitrage-Möglichkeiten an. Dies ist der börsenübergreifende Funding-Rate-/Basis-Arbitrage-Schnitt für Krypto – unterschieden von den Single-Exchange-Funding-Rates-Feeds (eine Börse), der Spot-versus-Perpetual-Basis und den Preis-APIs im Katalog. Funding erfolgt pro Intervall (die meisten Börsen wickeln alle 8 Stunden ab); die Annualisierung geht von drei Abrechnungen pro Tag aus, und die Intervalle können je nach Börse variieren, daher vor dem Handel überprüfen. Coins sind Bases (BTC, ETH).

Der einzelne Übersichtsindikator dafür, wie der Krypto-Optionsmarkt positioniert ist, live aus dem öffentlichen Optionsbuch von Deribit berechnet – kein API-Key, nichts gespeichert. Das Put/Call-Verhältnis ist die Menge der Put-Aktivität geteilt durch die Call-Aktivität: Ein niedriges Verhältnis bedeutet, dass der Markt mit Calls beladen ist (bullish, gierige Positionierung), ein hohes Verhältnis bedeutet, dass Puts dominieren (Absicherung, Angst). Der Ratio-Endpunkt gibt für eine Währung (BTC oder ETH) das marktweite Put/Call-Verhältnis auf zwei Arten zurück – nach offenem Interesse (die aktuelle Positionierung) und nach 24-Stunden-Volumen (der heutige Fluss) – mit den Call- und Put-Gesamtsummen, dem Spot-Index und einem verständlichen Sentiment-Label. Der Expiries-Endpunkt unterteilt das Put/Call-Verhältnis nach Verfall und zeigt die Laufzeitstruktur des Sentiments: ob die Absicherung im nahen oder im weiteren Bereich konzentriert ist. Dies ist der aggregierte Options-Put/Call-Sentiment-Schnitt für Krypto – unterschieden von der US-Aktien-Put/Call-API (ein anderer Markt), der Max-Pain-/Open-Interest-Positionierungsansicht, der impliziten Volatilitäts-Skew-Oberfläche und den Gamma-Exposure-APIs im Katalog. Unter etwa 0,7 ist es call-lastig und bullish, über 1,0 put-lastig und defensiv; am nützlichsten ist es als konträrer Indikator. Die Währung ist BTC oder ETH, die beiden Assets, für die Deribit liquide Optionen listet.

The shape of the crypto dated-futures curve and the annualised basis at every expiry, read live from Deribit's public futures book — no key, nothing stored. A single spot price tells you nothing about what the market pays to hold a position over time: dated futures trade at a premium (contango) or a discount (backwardation) to spot, and that premium, annualised, is the cash-and-carry yield basis traders harvest. The curve endpoint returns, for a currency (BTC or ETH), the spot index, the perpetual and every listed dated future — each with its days to expiry, mark price, the absolute and percent basis to spot and the annualised basis — plus the overall curve shape (contango or backwardation) and the front- and back-month annualised basis. The basis endpoint returns the annualised basis (cash-and-carry yield) for a chosen expiry, or the front future. This is the futures-curve / term-structure cut for crypto — distinct from the spot-versus-perpetual basis API (a single point on the curve), and from the funding-rate, options, max-pain, gamma and price APIs in the catalogue. Currency is BTC or ETH; expiry is a Deribit code like 26JUN26.

Der "Angstmesser" des Kryptomarktes und die Prämie, die Optionsverkäufer verdienen, live aus Deribits öffentlichem DVOL-Index und Binance-Kerzen gelesen — kein API-Key, nichts gespeichert. DVOL ist Deribits 30-Tage-Forward-Implied-Volatility-Index für BTC und ETH, das Krypto-Äquivalent zum VIX: die einzelne Zahl, die angibt, wie viel Volatilität der Optionsmarkt einpreist. Der Index-Endpunkt gibt den aktuellen DVOL, die Sitzungseröffnung/-hoch/-tief/-schluss, die 24-Stunden-Änderung und ein Regime-Label in einfacher Sprache (niedrig, normal, hoch, extrem) zurück. Der vrp-Endpunkt berechnet die Varianzrisikoprämie — implizite Volatilität (DVOL) minus die tatsächlich in den letzten 30 Tagen gelieferte realisierte Volatilität (annualisierte Standardabweichung der täglichen Log-Renditen aus Binance-Kerzen): wenn die implizite deutlich über der realisierten liegt, werden Optionsverkäufer mit einer Prämie bezahlt und das reich/billig-Signal zeigt es an; wenn die implizite unter der realisierten liegt, sind Optionen im Vergleich zur Marktentwicklung billig. Der History-Endpunkt gibt die DVOL-Index-Zeitreihe zurück. Dies ist der Implied-Volatility-Index / Variance-Risk-Premium-Bereich — abgegrenzt von der Realised-Volatility-API (die kein implizites Bein hat), den Equity-VIX-Familien-Indizes und den Option-Chain-, Skew- und Gamma-APIs im Katalog. Währung ist BTC oder ETH (die Assets, für die Deribit DVOL veröffentlicht).

Where option-dealer hedging flows concentrate, and whether they damp or amplify price moves — computed live from Deribit's public option book, no key, nothing stored. Each open option carries gamma; when dealers are net long gamma they hedge against the move (buy dips, sell rips) and volatility is suppressed, and when they are net short gamma they hedge with the move and volatility is amplified. The gex endpoint aggregates Black-Scholes gamma across every listed expiry, weighted by open interest, into the net dealer gamma exposure (in dollars per 1% move), the call and put gamma split, the zero-gamma flip level — the spot price at which net GEX crosses zero, the boundary between the mean-reverting (positive-gamma) and trending (negative-gamma) regimes — where spot sits relative to it, and the strikes holding the most gamma (the pinning magnets and acceleration zones). The profile endpoint returns GEX by strike, across all expiries or one. The expiries endpoint returns net GEX per listed expiry. This is the dealer-gamma / GEX analytics cut for crypto — distinct from the max-pain / open-interest positioning view, the implied-vol skew surface, the raw option chain and the single-option Black-Scholes pricer in the catalogue. GEX uses the SpotGamma convention (dealers long calls / short puts, r=0) and Black-Scholes gamma from mark IV — a model estimate of positioning, documented as such, not exchange-reported dealer inventory. Currency is BTC, ETH, SOL or XRP.

Die Form der impliziten Volatilitätsfläche von Kryptowährungen, live aus dem öffentlichen Optionsbuch von Deribit berechnet – kein API-Key, nichts gespeichert. Eine einzelne At-the-Money-Zahl verbirgt, was der Optionsmarkt wirklich sagt. Der Skew-Endpunkt gibt für eine Währung (BTC, ETH, SOL, XRP) und ein Verfallsdatum die ATM-implizite Volatilität, die impliziten Volatilitäten einer Out-of-the-Money-Put- und Call-Option bei einer gewählten Moneyness, den Risk Reversal (Call-IV minus Put-IV – positiv bedeutet, dass Calls nachgefragt werden und Aufwärtspotenzial bevorzugt wird, negativ bedeutet, dass Puts nachgefragt werden und der Markt für Absicherung nach unten zahlt) und den Butterfly (Durchschnitt der Flügel minus ATM – wie konvex das Lächeln ist) zurück. Der Termstructure-Endpunkt gibt die ATM-implizite Volatilität für jedes gelistete Verfallsdatum zurück, sodass Sie sehen, ob die kurzfristige Volatilität über der langfristigen liegt (Backwardation, Stress) oder darunter (Contango, der ruhige Standard). Der Smile-Endpunkt gibt die vollständige implizite Volatilitätskurve über die Ausübungspreise für ein Verfallsdatum zurück – das klassische Volatilitätslächeln. Dies ist die Volatilitätsflächen-Analytik für Kryptowährungen – abgegrenzt von der rohen, vertragsspezifischen Optionskette, der Max-Pain-/Open-Interest-Positionsansicht, der realisierten Volatilitätsreihe und den US-Aktien-Put/Call-APIs im Katalog. Währung ist BTC, ETH, SOL oder XRP; Verfallsdatum ist ein Deribit-Code wie 26JUN26 (für das nächste Verfallsdatum weglassen).

Where the crypto options market is positioned, and the strike toward which an expiry's open interest exerts the most "pain" — computed live from Deribit's public option book, no key, nothing stored. Max pain is the strike at which the total value of all open options is lowest at expiry: the price at which the greatest dollar amount of option open interest expires worthless and option writers keep the most premium. Traders watch it because price often gravitates toward max pain into a large expiry. The maxpain endpoint takes a currency (BTC, ETH, SOL, XRP) and an expiry and returns the max-pain strike, the spot/underlying, how far spot sits from max pain, and the call and put open-interest totals with the put/call OI ratio. The oi endpoint returns the full open-interest-by-strike distribution for an expiry — which strikes hold the most open interest, the magnets and walls (support & resistance) traders watch. The expiries endpoint lists every listed expiry with its aggregate open interest, contract count and call/put split. This is the aggregate options-positioning / max-pain analytics cut for crypto — distinct from the raw per-contract option chain (greeks/IV), from US equity options and from the crypto-volatility APIs in the catalogue. Currency is BTC, ETH, SOL or XRP; expiry is a Deribit code like 26JUN26.

api.oanor.com/maxpain-api

Live (15-minute delayed) options put/call sentiment analytics for US stocks and indices, computed from CBOE's public delayed-quotes feed. The ratio endpoint aggregates the entire option chain into the headline sentiment gauges — the put/call ratio by volume and by open interest, the total put and call volume and open interest, the contract counts, and the underlying price with its 30-day implied volatility (IV30) — plus a plain-language sentiment lean. The expiries endpoint breaks the put/call ratio down by expiration date, giving the term structure of sentiment. The strikes endpoint maps call-versus-put volume and open interest across strikes for an expiration, showing where positioning sits. This is the computed options-sentiment and positioning view — ratios and skew, not a contract dump — distinct from the raw options-chain, the volatility-index and the options-pricing calculators in the catalogue. US index options use an underscore-prefixed symbol (_SPX, _VIX); a ratio above 1 means more puts than calls (defensive/bearish lean). Live, no key on the upstream, nothing stored.

api.oanor.com/putcallratio-api

Live (15-minute delayed) US equity and index options chains, served from CBOE's public delayed-quotes feed. For any optionable ticker the summary endpoint returns the underlying quote — current price, day change, open/high/low/close, volume, bid/ask and the 30-day implied volatility (IV30) with its change. The expirations endpoint lists every available expiration date with its call and put contract counts. The chain endpoint returns the option contracts themselves: for each strike and expiry it gives the call/put bid, ask, last, implied volatility, open interest, volume and the full greeks — delta, gamma, theta and vega — and can be filtered by expiration date and by call or put. US index options are addressed with an underscore prefix (_SPX, _VIX). This is the single-name equity and index options surface — strikes, expiries, IV and greeks — distinct from the options-pricing calculators, the crypto-options and the FX/rate APIs in the catalogue. Live, no key on the upstream, nothing stored.

Live on-chain options and perpetuals data from Aevo, a leading decentralized derivatives exchange — no key, nothing stored. This is the on-chain options view: the full option chain with strikes, expiries, mark prices, implied volatility and the option greeks, plus live perpetual stats, distinct from the Deribit-based and other derivatives APIs in the catalogue — Aevo is an on-chain options and perps venue. The options endpoint returns the option chain for an asset — calls and puts by strike and expiry, each with mark and index price, implied volatility and the greeks (delta, gamma, theta, vega, rho). The stats endpoint returns the live perpetual statistics for an asset: open interest, index and mark price, the 24h change, funding and 24h volume. The expiries endpoint lists the available option expiries with their strike range so you can navigate the chain. Build options dashboards, volatility surfaces, greeks calculators and derivatives-trading tools on top of real on-chain Aevo data. Options are listed for BTC, ETH and HYPE; filter by type=call|put and expiry=YYYY-MM-DD, and greeks and IV come straight from the venue.

Live on-chain crypto options trading volume — the decentralized options market where protocols like Derive, Aevo, Premia, Ithaca and Rysk let users trade calls and puts on-chain, powered by the public DeFiLlama options feed, no key, nothing stored. This is distinct from a centralized options exchange order book: it measures the volume actually flowing through on-chain options venues. The overview endpoint returns the whole on-chain options market's volume over the last 24 hours, 7 days and 30 days plus every protocol ranked by what it trades, measured as notional (contract face value, the default) or premium (what option buyers actually paid). The protocol endpoint returns a single protocol's notional and premium volume side by side across 24h / 7d / 30d / all-time. The chain endpoint returns the options volume and top venues for one blockchain. See which on-chain options venue leads and how DeFi options flow shifts. This is the on-chain options-volume cut of DeFi — distinct from the centralized options-chain, spot-DEX, swap-aggregator, fees and perpetual APIs in the catalogue.

Live ranking and directory of crypto derivatives venues — the platforms that run perpetual and futures markets — served from the public CoinGecko feed with no key and nothing cached. This is a venue-level view of the derivatives market, distinct from spot-exchange directories, per-contract open-interest feeds and single-exchange tickers: it ranks the derivatives platforms themselves. The exchanges endpoint returns the venues ranked by open interest (or by 24-hour volume), each with its open interest in BTC, 24-hour derivatives volume in BTC, the number of perpetual and futures pairs it lists, its country and the year it was established — so one call tells you who the biggest derivatives venues are and how concentrated open interest is. The exchange endpoint returns a single venue's full profile by id. The list endpoint returns every derivatives-exchange id and name for lookup and autocomplete. Everything is read live from CoinGecko on each request, nothing stored beyond a short protective cache. Ideal for derivatives dashboards, open-interest and market-structure analytics, venue comparison and trading tools. Live, no key. 3 endpoints. For per-contract funding and open-interest history use a derivatives or open-interest API.

Live derivatives and spot market data from Bybit, one of the largest crypto-derivatives exchanges, straight from its public v5 API. Built for perpetual swaps: the ticker returns a contract's last, mark and index price together, the 24-hour change, high, low, volume and turnover, the live open interest in contracts and in USD, and the current funding rate with the next funding time — a whole perp in one call.

Linear (USDT) perps, inverse (coin) perps and spot are all reachable via the category parameter. Live, no key, nothing stored. Distinct from Coinbase, Bitstamp, OKX, Gate.io, Bitfinex and Gemini venue APIs and from aggregated derivatives feeds — this is Bybit's own ticker, funding history, open interest and candles. Perfect for trading, charting, derivatives-analytics and risk apps.

Live market data from OKX, one of the largest crypto exchanges, across both spot and perpetual markets, served straight from its public v5 API — no key, nothing cached. The ticker endpoint returns any instrument's snapshot — last price, best bid and ask, 24-hour open/high/low, volume and the 24-hour percentage change — for a spot pair like BTC-USDT or a perpetual swap like BTC-USDT-SWAP. The tickers endpoint returns every instrument of a type (spot, swap or futures) in one call, sortable by 24-hour change or volume. The candles endpoint returns OHLC candles at a bar you choose, from one minute to one month. The funding endpoint returns the funding rate of any perpetual swap — the periodic payment between longs and shorts — with the rate annualised to an APR and the next funding time, the signal perpetual-futures traders watch. Everything is OKX's live venue data, nothing stored. This is the OKX price, perpetual-funding and candle layer for any trading, charting, derivatives or market-data app. Distinct from Coinbase, Bitstamp, Binance and Kraken venue APIs and from aggregated feeds — this is OKX's own spot and perpetual order flow and its per-contract funding rates. 4 endpoints, no key on our side, real-time.

Live cross-exchange perpetual-futures market data — no key, nothing cached. Where single-exchange APIs show one venue, this compares the whole derivatives market across every exchange at once. The contract endpoint takes a symbol (BTCUSDT, ETHUSD) and returns that contract on every exchange that lists it — the mark price, the funding rate, the basis, the open interest and the 24-hour volume on Binance, Bybit, OKX, MEXC, Hyperliquid and the rest side by side, so you can instantly see where funding is richest and where the open interest sits (BTCUSDT trades on dozens of venues with billions in open interest each). The exchanges endpoint is the derivatives-exchange league table, ranked by open interest in BTC, with each venue's 24-hour volume and number of perpetual and futures pairs. The top endpoint surfaces the largest contracts market-wide by open interest or by volume. This is the cross-exchange derivatives layer for any trading, funding-arbitrage, risk or analytics app. Live from CoinGecko, nothing stored. Distinct from single-exchange funding and open-interest APIs — this is the whole perpetual-futures market across exchanges. 4 endpoints.

Live crypto spot-versus-perpetual basis and premium as an API, served from the Bybit v5 feed. The basis is the gap between a coin's perpetual-futures price and its spot price: when the perp trades above spot the market is in contango (leveraged longs are paying up), when below it is in backwardation. For any coin this returns the spot price, the perp last, mark and index price, the basis in absolute and percentage terms, the mark-to-index premium, the market structure, and the funding rate — per-8-hour and annualised — that arbitrages the basis away. Get a coin's basis, or scan the majors ranked by basis. The cash-and-carry and funding-arbitrage signal layer for trading and dashboard apps. Live, no key, no cache. Distinct from funding-rate, open-interest and price APIs — this is the spot-perp basis.

Live open-interest history and trend for crypto perpetual futures, served from the Bybit v5 feed. Open interest is the total value of outstanding contracts — its trend, rising or falling alongside price, is the signal traders use to confirm a move or spot a squeeze. For any USDT perpetual this returns the latest open interest in contracts and in USD, how it has changed over your chosen window, the rising / falling / flat trend, and the full time-series across 5m, 15m, 30m, 1h, 4h and 1d buckets. Look a contract up by symbol (BTCUSDT) or base coin (BTC), pull its open-interest history, or list every tradable perpetual. Live data, no cache. Distinct from a funding-rate API (which carries the rate snapshot) and from price / ticker APIs — this is the open-interest time-series and trend layer.

Live crypto long/short trader-positioning sentiment as an API, streamed from the Bybit v5 public account-ratio feed. For any USDT perpetual futures contract it returns the share of accounts positioned long versus short (buy/sell ratio) and the derived long/short ratio — either the latest reading or a full time-series across 5m, 15m, 30m, 1h, 4h and 1d buckets. The crowd-positioning signal traders use to spot one-sided, over-leveraged markets. Look up by symbol or base coin, pull history, or list tradable symbols. Live, no key. Distinct from funding-rate, price and open-interest APIs — this is the account long/short sentiment.

Live crypto perpetual funding rates and derivatives data as an API, streamed from the Bybit v5 public market feed. For every USDT perpetual futures contract: its symbol, last / mark / index price, the current funding rate (per interval, plus percentage and annualised), the next funding time, open interest, 24-hour volume and turnover, and 24-hour price change. Look a contract up by symbol or base coin, rank contracts by funding, open interest, turnover or price move — a ready-made signal for crowded longs and shorts — search, or list them all. Built for trading, quant, dashboard and signal apps. Distinct from spot-price and on-chain data.

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.

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.
