Batch Market Cap API FAQs
Can I retrieve the 15 largest market cap stocks for each sector using the company-screener endpoint?
Currently, you can add the market cap parameter to the company-screener endpoint to filter stocks based on a specific market cap value, but the data will not be returned in sorted order from largest to smallest.
Is market capitalization data for European stocks available in the Starter package?
Yes, the Starter plan for $29 allows you access to market cap data for European stocks.
Does the FMP.HISTORICALMARKETCAPITALIZATION formula have an 'interval' parameter?
No, the FMP.HISTORICALMARKETCAPITALIZATION formula does not have an 'interval' parameter. The formula is limited to a maximum of five years of data and does not include an 'interval' parameter.
Why are after-market and pre-market prices different from other platforms?
After-market and pre-market prices can vary between platforms due to differences in data sources and low trading liquidity during those sessions. We use multiple exchange feeds to provide this data, but some brokers and platforms rely on proprietary or restricted feeds that we can't redistribute due to compliance limitations. As a result, you may notice slight differences in prices—especially for lower-volume stocks or during off-hours trading. If you’re seeing significant discrepancies, feel free to share the sources you're comparing us with, and we’ll be happy to investigate further. Just keep in mind that pre/post-market pricing often varies depending on the exchange and broker used.
Do you provide a specific API endpoint for small, mini, and micro cap financial data?
No, we do not provide a specific endpoint that returns this data. Our API offers a wide range of financial data, but specific categories like small, mini, and micro cap may not have dedicated endpoints.
Why does the /stable/aftermarket-quote?symbol=AAPL API return zero volume for the current time?
The volume displayed in the API represents the day volume. If the market is not open yet (pre-market), the volume will be zero. For the volume of the last trade, it is displayed as lastSaleSize.
What price is displayed after the market closes until it opens again for equities?
For equities, there is no price displayed after the market closes until it opens again. However, you can check this data during pre and post-market hours using the Aftermarket Trade API.
