What is an API Request?
Pricing is based on the number of monthly API requests allowed. Each time the marketstack API service is used to look up data for one specific stock ticker, one API request is consumed. As a result, if a given API request contains 5 tickers (symbols), 5 API requests will be consumed. API errors are not counted towards your monthly quota.
What happens if I exceed my API Request volume?
Users will be automatically notified via e-mail and on their Account Dashboard once at least 75%, 90%, and 100% of their monthly API Request allowance has been reached. After reaching 100% of the allowance, overages fees will apply so we make sure you won’t experience any disruptions and your website/application will keep running smoothly. You can learn more about overages billing here.
What is the API's uptime?
The marketstack API's system status is kept track of 24/7 by the apilayer team. We keep the amount of outages or service disruptions at a minimum and are proud to have an uptime of nearly 100%, calculated based on the last 365 days. Interested in seeing the details?

What is the difference between free and paid subscriptions?
At marketstack we offer a Free Plan that will allow users to make up to 1.000 market data API requests per month, supporting end-of-day data as well as 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 you need to take into account 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 can I change my payment frequency?
In order to change your billing frequency from monthly to yearly or from yearly to monthly, you will be required to downgrade your account back to the Free Plan.
Step 1: Navigate to the Subscription page, click "Downgrade" in the Free Plan section and confirm your downgrade. Downgrades are not effective immediately, your premium subscription will remain active until the end of the current billing period.
Step 2: Once your billing period ends and your account downgrade has become effective, navigate back to the Subscription page and click "Upgrade" in your preferred subscription plan's section. You will now be aked to choose a new billing frequency.
If you need any assistance changing your billing frequency, please do not hesitate to contact us.
