Customer Reviews
Good for my small project
I tried out the free tier first, then upgraded to Basic for some Penny Stocks Data. It worked out pretty well for my personal project. The data was there when I needed it, and the API was easy enough to figure out. Didn't have any big problems, which is always nice. It just made things simple.
Good data, minor setup issues
I signed up for the Basic plan to get access to the Historical Stock Data API. The data itself was quite reliable and comprehensive for the tickers I needed. Integration with my Python script was straightforward enough, and the documentation was helpful. My only small gripe was getting the initial API key activated; it took a few tries before it registered correctly. Overall, decent value for the price, but that initial hiccup could be smoother for new users.
Absolutely love this data!
I got the Growth plan for the Real-Time Stock Data API and also the Currency Exchange Rates API, and it's fantastic! The speed is incredible, and the data is so clean and easy to use. Setting it up with my Node.js app was a breeze. I had everything running perfectly within an hour. This is exactly what I needed for my project. I'm definitely going to use them again!
Consistently reliable service
This is my third time using Marketstack, previously for Historical Stock Data and now for their End-of-Day EOD Stock Prices. Each time, the service has been consistently reliable. The data quality is always high, and the API uptime is impressive. I appreciate that I can depend on them for consistent access to financial data without unexpected downtimes. It's why I keep coming back instead of trying other providers.
Fast and accurate data
Needed Real-Time Stock Data API. Got it. Integrated easily. Data was quick and accurate. No issues.
Detailed API experience
I ordered the Professional plan specifically for the Intraday Market Data API and also wanted to explore the Technical Indicators API. The ordering process was simple, and I received my API key almost instantly. Delivery of the data through the API was consistently fast, with low latency as advertised. I tested it against several major global exchanges, and the data points were accurate. Customer support was responsive when I had a question about rate limits for a specific use case; they got back to me within a few hours with a clear explanation. The usability of the JSON responses is good, making parsing relatively easy. I found the documentation on Python integration particularly useful. It's a solid service for what it offers.
