Choosing a
stock data API.
How OHLC stacks up against other stock market data APIs on price, licensing and the data you actually get, built from each provider's public pricing and documentation.
Most stock APIs are priced for one person. The moment a colleague, a tester or a customer sees the data, the cheap plan stops applying: business use costs several times more, and at many providers it starts with a sales call. OHLC publishes that price instead: $149 a month covers internal use for your team, and $899 a month covers showing data to your customers, both bought online.
OHLC is built for U.S. stocks and ETFs, and goes deep there: fundamentals and SEC filings on every plan, point-in-time identity that keeps backtests honest across ticker changes, prices reconciled across licensed sources before they are published, and a hard-capped bill with no overages. Pro and above add Canada, the UK, France, the Netherlands and Australia. If you need real-time ticks or other markets, each comparison below says which provider fits better. Every page lists its sources and the date the facts were checked.
