Crypto APIs Inc. is a registered brand in Delaware, United States. ## Which blockchain networks are supported? We currently support over 50 blockchains, including their testnets and mainnets. Detailed information about the supported networks is available on each dedicated service webpage. For some products, such as "Dedicated node as a service", we offer extended support beyond the listed blockchains. ## Do you support testnet networks? Yes, we support testnet networks for multiple blockchains. We also offer a free subscription plan to be used over testnet networks. ## Do you use one node per network? We have a pool of nodes that we use, all hosted with us. If one goes offline, there is always another that will continue processing. ## Do you use your own nodes or shared ones? We don't use shared nodes. The pool of nodes we use is owned by Crypto APIs. ## How can I contact support? You can contact our support team via Live Chat or Support Email. When you contact us, please use the email address associated with your Crypto APIs account, or the email added as a Team member in another Crypto APIs account. ## Do you offer a free plan/trial/demo for Crypto APIs? We do not offer a trial or demo for Crypto APIs products. We do, however, offer a free subscription instead, which can be used over testing networks. ## Can I use more than one Crypto APIs product at once? Yes, you can use as many of our services as you wish. Our blockchain infrastructure provides flexibility and allows you to continue using us even after you reach your subscription plan limits. ## I need more custom settings for my subscription — is it possible? Yes. We have a Custom option for subscription. To set it up, you can discuss it directly with one of our representatives by [contacting our team](/custom-plan). ## What is Pay As You Go? Pay As You Go is our pricing model designed to eliminate any restrictions that could limit 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 email, and Pay As You Go will automatically let you continue using our services without interruption at a slightly higher cost. ## How can I pay for the service? We accept payment methods such as debit and credit cards (Visa, MasterCard) via our payment provider Stripe. We can also offer alternative ways to pay for your subscription plan, such as wire transfers, cryptocurrency, or PayPal. For more information, contact our business development team. ## Are payments for Crypto APIs services recurring? Yes, our service plans are subscription-based, with payments recurring automatically until customers cancel their subscriptions. Upon cancellation, clients are responsible for covering the costs of the current payment term; the subscription is cancelled at the start of the next payment cycle. ## Can I prepay for my subscription for a longer period? Yes, you can. Please contact our team to discuss the duration, payment methods, and terms. ## Do you offer discounts? We may offer discounts based on your subscription. Discounts are available for larger packages and longer-term (yearly) subscriptions. If you believe your subscription qualifies for a discount, please contact our team. ## What happens when I cancel my plan subscription? If you cancel your subscription, you will continue to have access to our services until the end of your current payment cycle, after which your paid services will be discontinued. For example, on a monthly subscription cancelled halfway through the month, you keep access for the remaining two weeks. Note that 30 days after cancellation, all data associated with your account — including your fund balance in Wallet as a Service and Blockchain Automations — 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 requests per second included in a client's chosen plan; clients can exceed the soft limit if necessary, with slightly higher credit consumption. Once the hard throughput limit is reached, clients have reached the absolute maximum allowed. To increase your hard throughput limit, upgrade your plan or contact us to create a custom plan. ## How many credits does an endpoint cost? You can see the credit cost for each endpoint in our official documentation. Select the endpoint you want and the credit cost is displayed at the end of the page. ## Related - [Pricing](/pricing) - [Custom plan](/custom-plan) - [Contact](/contacts)
