October 6, 2025Is there any free stock market API that allows publishing on a website?
Hi there, I design financial-based web apps that perform all kinds of stock market functions and analysis. My first question is, what do you want to build and why? Would you like to monetize your work somehow via advertising or subscriptions, etc.? I only ask because unless you are using stock data on your own computer and not making it available to others via an app or a website, you are really not going to find anything legally for free. I pay for several services and I can say that the biggest advantage to that is that you can rely on your data to be working most all of the time. If you are using a free "hack" you never know when everything will just shut off and if you need reliability, you should really pay for a feed. Anyway, hit me up if you want to chat about your project, goals and so forth. I've helped numerous people over the years set up their own, customized SaaS businesses revolving around financial dashboards, etc. Cheers! More on reddit.com

r/algotrading on Reddit: What (preferably free) API's are preferred for 'real-time' stock data?
October 6, 2025 -
Yes, I know it's been asked 17 million times. The problem is, there are 58 million answers and the vast majority of them are sarcastic, rhetorical, or a simple "try this platform" without explanation of why.
I'm mostly just wanting an API that integrates well with Python that provides as real-time information as possible for a single stock symbol at a time. I believe my current usage is somewhere around 100 call/min IF I happen to be holding a stock. My calls per day is significantly lighter. I would prefer a free version, but I wouldn't mind paying a little bit if it was significantly more consistent and up to date.
Here are some that I have tried and problems I've had with them:
- yFinance seems to be delayed a little bit, but there's another weird thing going on. I've run 2 functionally identical programs side-by-side and one of them will start pulling the new price a good 20+ seconds before the other one, which is kinda a lot!
-Alpaca (free) seems to update slower than yFinance, which is odd given what I've been able to find with a google search. It also held the 'current price' at the Open of the minute that a particular stock was halted and not the Last (or Close) price when the halt was initiated. It also didn't update until 30s after trading was resumed.
Again, I'm not particularly opposed to paying a bit for 'live' data IF that data is truly "real-time" (meaning within the last couple seconds) (Alpaca does not) and returns the properly updated value with each API call (yFinance does not).
yFinance price changes are underlined in red. Both programs were running on the same machine in parallel and made a new API call every time it wrote to the logs. Timestamps are in Central time. Top answer 1 of 16

Most brokerages that provide an API for trading also have an API for market data, usually without any additional fees. Tradier and IBKR are both good options for this. You don't even need to make any trades through them to use the data as long as you have an active brokerage account.
