Standout features
What Alpha Vantage does best
- Cloud-native REST APIs for realtime and historical financial data across global stocks, ETFs, mutual funds, FX, cryptocurrencies, commodities, technical indicators and macroeconomic indicators in a single unified portfolio of endpoints.
- Global equity time series APIs (daily, weekly, monthly and intraday 1–60 minute bars) with 20+ years of history, optional split/dividend-adjusted prices, and support for extended trading hours where available.
- US options data APIs providing realtime and historical option chains with 15+ years of history, full market/volume coverage, and optional Greeks and implied volatility fields in JSON or CSV.
- Fundamental data suite covering company overview, income statement, balance sheet, cash flow, dividends, splits, shares outstanding, ETF profile & holdings, listing/delisting status, earnings history, earnings estimates, and earnings/IPO calendars.
- Alpha Intelligence™ endpoints for market news & sentiment, earnings call transcripts, top gainers/losers, insider transactions, and fixed/sliding-window analytics, built with in‑house AI and quantitative expertise.
What Dilution Tracker does best
- Dilution profiles focused on US-listed small caps; tracks dilution sources such as shelves, warrants, ATMs and convertibles (custom coverage ~2,500 tickers is referenced in alerts docs).
- Shares outstanding (O/S) chart shows historical split-adjusted O/S plus stacked “potential dilution” bars for ATM, S-1 offering, warrants, equity line, and convertible notes/preferred.
- Offering readiness: indicates whether a company can offer via a registered shelf or a pending S-1 offering (and notes private placements are possible but rarer).
- Proprietary ratings referenced in the knowledge base include a “dilution risk rating” and an “offering ability rating” based on available shelf capacity (S-3) or pending S-1 offerings.
- Data maintenance: tracks SEC filings and company press releases for covered tickers and updates values when new dilution-related disclosures occur; new companies are added when they match coverage criteria.
