Stochastic & Oscillators API

healthy 4,369 Subscribers

Live OHLC momentum-oscillator analytics that traders run to spot overbought and oversold turns, computed on demand from the OHLC candles you pass in — no key, no cache, nothing stored. The stochastic endpoint returns the Stochastic Oscillator %K and %D, the classic measure of where the close sits inside its recent high-low range, with the %D signal line. The williams endpoint returns Williams %R, the same idea on a -100 to 0 scale. The cci endpoint returns the Commodity Channel Index, which flags how far the typical price has strayed from its average. Each result comes with an overbought or oversold reading so you can act on it immediately. These oscillators all need the full high, low and close — that makes them a different tool from closes-only indicator APIs like RSI and MACD, and from volatility and ATR tools: they measure momentum by where price sits within its range. Works for any market — forex, stocks, crypto or commodities — because you supply the candles. Computed locally and deterministically, so it is instant and private. Ideal for trading bots, screeners, signal dashboards and back-tests. Stochastic period defaults to 14 (smoothing 3); CCI to 20; Williams %R to 14. Live, nothing stored. 3 compute endpoints. For RSI, MACD or Bollinger Bands use a technical-indicators API.

555 Timer Calculator API

555-timer (NE555) astable and monostable design as an API, computed locally and deterministically. The astable endpoint designs the classic oscillator: from the two timing resistors R1 and R2 and the capacitor it returns the output frequency f = 1/(ln2·(R1+2R2)·C), the high and low times (T_high = ln2·(R1+R2)·C, T_low = ln2·R2·C), the period and the duty cycle (R1+R2)/(R1+2R2), or solves the capacitor for a target frequency. The monostable endpoint designs the one-shot timer, T = 1.1·R·C — the pulse width of a single output pulse — and solves for whichever of the resistance, capacitance or pulse width you leave out. The design endpoint works backwards: from a target frequency, a chosen capacitor and a duty cycle it computes the resistor values R1 and R2 you need (a standard 555 needs a duty above 50 %). Capacitors may be entered in farads, microfarads, nanofarads or picofarads. Everything is computed locally and deterministically, so it is instant and private. Ideal for electronics-hobbyist and maker tools, oscillator, blinker, PWM and timing-circuit design, and electronics education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is 555-timer design; for Ohm's law, reactance and RC time constants use an Ohm's-law API.

Momentum & Collision API

Linear momentum, impulse and one-dimensional collisions as an API, computed locally and deterministically. The momentum endpoint computes the linear momentum p = m·v of a moving body, with its kinetic energy, and solves for whichever of the mass, velocity or momentum you leave out. The impulse endpoint applies the impulse-momentum theorem, J = F·Δt = m·Δv = Δp: from a force and a time it gives the impulse and, with a mass, the change in velocity; or from a mass and a velocity change it gives the impulse and the average force over a contact time — the physics of a bat hitting a ball or an airbag softening a crash. The collision endpoint solves a head-on collision between two bodies using conservation of momentum and a coefficient of restitution: e = 1 for a perfectly elastic collision (kinetic energy conserved), e = 0 for a perfectly inelastic one (the bodies stick together), or any value between for a partially inelastic collision — returning both final velocities, the conserved total momentum, the kinetic energy before and after, and the energy lost. Everything is computed locally and deterministically, so it is instant and private. Ideal for physics-education and simulation tools, game and ballistics engines, vehicle-crash and sports apps, and engineering-dynamics software. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is linear momentum and collisions; for rotational angular momentum and flywheel energy use a flywheel API.

Stock Short Interest API

Live short-interest data for US stocks from Nasdaq — no key, nothing stored. The "how heavily is it shorted, and is a squeeze building" view of a stock: the number of shares sold short, the average daily volume and the resulting days-to-cover, reported each settlement period, distinct from the quote, movers, insider and analyst APIs in the catalogue. The current endpoint returns the latest short-interest reading together with the change from the prior period — a rising or falling short position with the share delta and percent change. The history endpoint returns the full settlement-by-settlement timeline so you can see how the short position has trended over the year. Days-to-cover — short interest divided by average daily volume — is the headline squeeze metric: the higher it is, the longer shorts would need to buy back their position. Build short-squeeze scanners, bearish-positioning dashboards, risk overlays and contrarian-signal bots on top of real Nasdaq short-interest data. Look up any US stock by its ticker; share counts are returned as clean numbers. Note that short interest is reported about twice a month and a few non-Nasdaq listings may not be covered.

US Company Financials & Fundamentals API

Live fundamental financials for US public companies straight from the SEC's official XBRL data — no key, nothing stored. The "what does the balance sheet and income statement say" view of a company: the actual reported revenue, earnings, assets and equity pulled from its SEC filings, distinct from the quote, analyst, insider and SEC-filings (EDGAR) APIs in the catalogue. The financials endpoint returns the latest annual key figures: revenue, gross profit, operating income, net income, total assets, total liabilities, shareholders' equity, cash, diluted EPS and the computed net margin. The concept endpoint returns the multi-year time series for a single metric — revenue history, net-income history and more — so you can chart how a company has grown. The company endpoint resolves a ticker to its SEC company (CIK and legal name). Build stock-screeners, valuation models, fundamentals dashboards and research tools on top of authoritative SEC data. Look up any US public company by its ticker; figures are the latest annual (10-K) values reported to the SEC in USD.
