StockData.org is a financial market data API service focused on free access to real-time, intraday, and historical stock data, as well as financial news, forex, and cryptocurrency data. Its website says it covers 150,000+ stocks/FX instruments and 70+ global exchanges, with market news from 5,000+ sources in 30+ languages. It is aimed at developers who want to embed market quotes and financial news into applications.
Functionally, it offers US stock prices, extended hours data, intraday data, historical EOD data, plus news data and sentiment analysis. In terms of historical coverage, the free tier includes only 1 month of intraday and EOD data, while Standard and higher plans provide 7+ years of intraday and EOD data. The API returns JSON; sample responses include fields such as ticker, price, day_high, volume, and last_trade_time, making it easy to integrate into frontend dashboards, backend aggregation services, or data pipelines. The available text does not specify supported programming languages, official SDKs, WebSocket support, or framework integrations.
Pricing follows a freemium subscription model. The free plan includes 100 requests per day and does not require a credit card. Basic is $29/month, Standard is $49/month, Pro is $99/month, and Pro 50K is $199/month. Annual billing offers roughly a 20% discount. The main differences between tiers are daily request limits, the number of symbols allowed per stock price request, the number of news articles, and the length of historical data coverage. The terms indicate support for Visa, Mastercard, and American Express, with billing in USD. Purchases are non-refundable, but subscriptions can be canceled at any time.
Its strengths are a low barrier to entry, an immediately usable free API key, broad market and news coverage, and data-product-oriented features such as bulk data, Market Stats, and metadata. The downsides are clear limitations on the free plan, no visible self-hosting option, and limited disclosure around official SDKs and data licensing details. For high-frequency or production-grade use cases, SLA, latency, and compliance requirements should be evaluated separately. It is best suited for financial news apps, market dashboards, quantitative research prototypes, and small to midsize data products.
The crawled text does not provide information on network availability in mainland China, payment compatibility, or localization support, so its accessibility from China is unknown. If you plan to use it in production from within China, it is recommended to first test direct connection stability, latency, and payment availability using the free plan. You may also want to evaluate alternatives such as Alpha Vantage, Finnhub, Polygon.io, Twelve Data, and IEX Cloud.
