Polygon’s API, [api.polygon.io/v2/snapshot/locale/us/markets/stocks/gainers](https://api.polygon.io/v2/snapshot/locale/us/markets/stocks/gainers), is a tool used by many traders for accessing lists of top gainers. However, as pointed out by users in forums, including Reddit, it can sometimes include stocks that have gapped up rather than those climbing throughout the day.
This can be a limitation if your strategy depends on identifying sustainable growth rather than temporary spikes. So, if you’re looking to refine your approach, it might be beneficial to look beyond Polygon.
### Exploring Reliable Alternatives
#### 1. Yahoo Finance API
Yahoo Finance is a household name when it comes to stock data. While it doesn’t officially provide a free API, their data can be accessed through various third-party libraries. This platform is known for its robust and updated data, making it a solid choice for tracking top gainers.
#### 2. Alpha Vantage
Alpha Vantage offers a free API allowing access to time series data and financial news. The platform is well-regarded for getting real-time and historical data. Although it requires setting up an account to get started, its vast resources make this small step worthwhile.
#### 3. Investing.com API (via Financial Modeling Prep)
Though Investing.com doesn’t directly offer an API, Financial Modeling Prep provides an API that aggregates data from Investing.com among other places. This API allows users to extract daily gainers’ data reliably, helping to mirror the curated insights seen on Investing.com’s main site.
