I use nasdaq datalink for most data. Still gotta source chart candles if you need that. Both nasdaq and nyse have FTP servers. Been a minute since I was snooping around. If memory serves tho. I believe one of them might have daily candles you can download. SEC also has an API with a good bit of data that's free. I scrape all three. Usually I grab the earnings calendar from nasdaq, then I scrape the SEC for each tickers CIK number. I use the CIK number to then automate filing scrapes when I need them... Pretty much all you need to start is sourced for free straight from the horses mouth. Only time you gotta start contemplating paying is when you start wanting shorter time frames than daily for your charts. Atleast that's been my experience.

r/algotrading on Reddit: Where can I find a free API with stock data for python?
November 17, 2024 -
I've been looking around for good APIs I can implement into different code to experiment with and so far the only good free one I found was Yahoo finance, however it's pretty limited but I can't find any other free ones, any suggestions?

November 17, 2024Is 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

There is a free API provided by Yahoo that contains up to date data related with several tickets. You can see the API details here. One example to extract metadata from a ticket would be:
import yfinance as yf
stock_obj = yf.Ticker("GME")
# Here are some fixs on the JSON it returns
validated = str(stock_obj.info).replace("'","\"").replace("None", "\"NULL\"").replace("False", "\"FALSE\"").replace("True", "\"TRUE\"")
# Parsing the JSON here
meta_obj = json.loads(validated)
# Some of the short fields
print("sharesShort: "+str( meta_obj['sharesShort']))
print("shortRatio: "+str( meta_obj['shortRatio']))
print("shortPercentOfFloat: "+str( meta_obj['shortPercentOfFloat']))
The output for the ticket you are interested in would be:
sharesShort: 61782730
shortRatio: 2.81
shortPercentOfFloat: 2.2642

You can use the free Yahoo Finance API and their most popular Python library yfinance. Link: https://pypi.org/project/yfinance/
Sample Code:
import yfinance as yf
GME_data = yf.Ticker("GME")
# get stock info
GME_data.info
Other than that you can also use many other API. You can search in RapidAPI and search "Stock".
