Access account data, orders, assets, positions, and many more. It’s paper trading API also allows you to test your codes, algorithm resets, etc. and offers a Streaming API that uses WebSockets to deliver real-time updates regarding trades.

It offers 2-factor authentication to secure all your API. You can also benefit from short selling and margins with advanced investing options, and it also supports trading strategies.

Alpaca facilitates efficient trading by allowing you to trade directly from the TradingView chart, which requires no tab switching or extra clicks. It offers powerful tools to boost your production like advanced order types like OCO, MOO, IOC, and MOC.

MorningStar API

MorningStar API is a good API to manage if you have lots of apps that you need to integrate with. The combination of their useful blogs and an easily navigable user interface makes for a good user experience.

Representation: As you can see from the screenshot, the data representation is incredibly simple to understand. MorningStar does a good job of ensuring each record comes in sequence rather than a complicated mess. Similar to FMP, the API provides data on crypto, forex, and some local markets.

Purchase Access: An unfortunate aspect of the MorningStar API is the challenge of getting access. To get access you must connect with MorningStar personnel, agree on a price, before finally being able to use this API. This is in stark contrast to FMP stock API which you can easily sign up for directly on the website.

Tradier API

As you may well have guessed from the name, Tradier API is both a data API and an online broker. Getting the subscription for their trading accounts, automatically gives you access to their data API.

Multiple Endnotes: Tradier does a great job of making integration with applications requiring stock data tracking straightforward. The broker platform gives traders great optionality when it comes to trading views and Tradier has over 100 endpoints updated per minute.

The smart API key authenticates endpoints during the performance which makes it easy to get going with and quite effective. Trading Platform: Unlike the other APIs aforementioned, the Tradier platform gives you the ability to make trades. Though there is a paywall to make any trades, its fee structure is good for low and high trade volume traders. The $30 per month subscription plan gives you commission-free trading of both equities and options - this subscription also allows full access to their real-time market data. The free option only allows access to delayed market data.

Intrinio

By neatly using the REST infrastructure, Intrinio can ensure that unique requirements and API calls made by users are quickly delivered in the JSON format. Once created users are quickly directed to multiple endpoints to get their data.

Hundreds of Datasets: One of the great strengths of this API is that with the one interface, they provide access to lots of different data you might require. They also provide their own algorithms that use machine learning and AI to arrange the data ensuring they provide sequenced and updated information.

Purchase and Access: Similar to FMP, Intrinio offers a great free plan to get you started. If you do want more data feeds then the paid plans are definitely recommended. Whilst FMP platform allows you to get going right away, the set up for Intrinio is quite challenging and requires you to use lots of different documentation. For programming beginners, this becomes quite a large barrier and for experts, we think it just seems unnecessary.
