What is Marketstack?
The Marketstack API was built to offer a stock market data solution, making it accessible to both developers and companies around the world. At this time, the API supports 30,000+ stock tickers from 2,700+ global stock exchanges.

What is the difference between free and paid subscriptions?
At Marketstack, we offer a Free Plan that allows users to make up to 1,000 market data API requests per month, supporting end-of-day data and up to 12 months of history. As soon as there is a requirement for more API requests or intraday data, users can choose from one of our premium subscription plans, available on our Pricing page, or contact us for a custom solution.
Which subscription plan fits my needs?
The most important factor to consider when choosing a subscription plan is the number of allowed monthly API requests. If you will stay below 100 monthly requests and only need end-of-day data, you can go for the Free Plan. If your volume exceeds 100 requests and/or you require more accurate, intraday data with regular updates, you will need to choose at least the Basic Plan. Other decisive factors include HTTPS encryption, technical support, and more.
Which payment methods are supported?
Payments can be made via credit card (Visa, MasterCard, Discover, Diner’s Club, American Express). Enterprise and high-volume customers may request annual bank transfer payments to be enabled. You can change your payment method at any given time in the “Payment” section of your account dashboard.
Can I also pay yearly?
Yes. If you choose annual billing, the total price of your subscription plan will be up to 15% lower than the total amount you would pay with a monthly payment frequency.
How do I cancel/downgrade?
You can initiate a cancellation or downgrade by selecting a new plan and providing at least one reason for your decision. The customer service team will cancel or downgrade your plan. Downgrades are not effective immediately; your premium subscription will remain active until the end of the current billing period.
How do I change between monthly and yearly billing?
To change your subscription from monthly to yearly billing, submit a request on the Contact Us page on the website, following these steps:
Step 1: Sign in to your account
Step 2: Go to the Contact Us page
Step 3: Fill out the form and choose the “Sales” category for this request.
Step 4: In the text box, include your specific request, for example, “Change from Monthly to Yearly subscription.”
