In the previous 100 years, humanity has achieved tremendous technological progress. These technological advancements have shown to be beneficial in a variety of fields, including information technology and agriculture.

This technological progress, which has an influence on every aspect of human existence, has had an influence on financial markets, particularly the stock market, and has resulted in a paradigm shift. Innovative technologies such as cloud-based application programming interface (API) have evolved in response to this shift, and their consequences have just lately begun to be seen.


Understanding Stock market APIs

Data consumers such as traders, investors, and software developers can easily gather and interact with each other thanks to exchanging APIs. Stock APIs are primarily used to make data sharing, access, and payment processes easier. It would be essential to create complicated code to extract the raw data directly from the stock market if these stock APIs did not exist. These APIs are a godsend since they allow for the retrieval of real-time stock market data in a nicely formatted, straightforward, and consistent manner. You may get more information about these APIs on Finage's website.

As previously said, Stock APIs excel in digesting raw market data and presenting it in a logical manner. These APIs can be used to track and forecast movements in equities, currencies, and fixed income instruments in applications like trade forecasting or other financial applications. As a result, by getting the most out of APIs, you may reduce risks while increasing profits. The stock API sector, as well as financial data in general, has nuances that describe quality, evolution, and how understanding them can help your algorithms.


Executive Summary

In the digital era, the financial market data business has seen a seismic change, with cloud-first application programming interfaces (APIs) usurping on-premise systems like Bloomberg computers and Reuters Eikon.

In this post, we'll look at some of the essential characteristics that make a market data supplier trustworthy. Then we'll look at six popular data suppliers in further detail:

We'll look at some of the most frequent traps to avoid while selecting a dependable market data API in this post. Warning: free stock APIs are not always equal to the finest stock APIs.


Stock API "Gotchas" – Avoiding Common Pitfalls

Stock APIs are programming interfaces that connect users of financial market data with the data sources they need. A data-driven market participant will need to create complicated scripts to interpret raw data from stock exchanges if they don't have access to a stock market API. In the United States alone, there are over ten stock exchanges, each "speaking" a different language when transferring trading data downstream. Some stock API service providers supply data that varies between 1% and 5% off, and you'll have to start over. There's more to an API than simply the data quality, and it's crucial to understand what you're obtaining.


Adjusted vs Unadjusted historical prices

There are things called "corporate actions" that can alter the closing price of a stock retrospectively. A stock split is an example of business action. A 2–1 stock split means a firm chose to double the number of shares each shareholder possesses while also halves the price of each share. If you built a strategy using uncorrected closing prices, you'd notice enormous price swings, which would throw your price forecast off.


Aggregation vs Exchange specific

You must know if the price data comes from a single exchange or an aggregation when you get it. Your data will always be inaccurate if you acquire price from one exchange but never trade on that exchange. Aggregation might be beneficial since it provides a more accurate price signal for the entire market.


Current Quotes vs Historical

If you're using a provider for historical pricing, you should also determine if it provides an up-to-date endpoint. This is a rather straightforward thing to keep an eye out for.


Always look for oddities or patterns

You must have a thorough understanding of your data. Each stock market API platform will have its own set of peculiarities. Each API might have its own set of oddities, which might be part of its allure. Look for YOUR oddities in addition to theirs. What methods do you use to gather data?

Wait! What about Yahoo Finance API or Google Finance API?

Google and Yahoo make a lot of money from digital advertising, and serving advertisements via APIs is difficult, if not impossible. The discontinuation of official support for Yahoo Finance API and Google Finance API was due to a lack of congruence between the advertising revenue model and the API business strategy. Both firms continue to operate as financial market information websites (with adverts, of course).

Yahoo Finance and Google Finance, for example, continue to operate as financial market information websites (with adverts, of course). On Yahoo Finance, there is still a download button for specific market data:

Financial data websites, on the other hand, are fundamentally distinct from financial data APIs.
