What is Pay As You Go?

Pay As You Go is our pricing model designed to eliminate any restrictions that could be limiting our clients from achieving their goals exactly when they need to. It enables customers on any of our paid plans to continue using our services beyond their plan's credit limit. Once you reach your credit limit, you will be notified by mail, and our Pay As You Go will automatically let you continue using our services without interruption at a slightly higher cost.

What happens when I cancel my plan subscription?

If you decide to cancel your subscription, you will continue to have access to our services until the end of your current payment cycle. After that, your paid services will be discontinued. For example, if you are on a monthly subscription and cancel halfway through the month, you will still have access to paid services for the remaining two weeks. Please note that 30 days after your subscription is canceled, all data associated with your account, including your fund balance in Wallet as a Service and Blockchain Automations Service, will be permanently deleted.

What is "Throughput"?

Throughput is the metric we use to measure the number of credits that can be spent per second. Each subscription plan includes both soft and hard throughput limits. Soft throughput represents the number of requests per second included in clients chosen subscription plan. Clients can exceed the soft limit if necessary, with slightly higher credit consumption than specified in their chosen subscription plan. However, once the hard throughput limit is reached, clients will have reached the absolute maximum allowed. To increase your hard throughput limit, please upgrade your subscription plan or contact us to create a custom plan that meets your specific needs.

How many credits does an endpoint cost?

You can see the credits cost for each endpoint in our official Documentation. Simply select the endpoint you want information for and the credits cost is displayed at the end of the page.
