Solutions

Six hubs, worded as the problems people actually search for. Each one opens with the workflow end to end — what triggers it, what you call, what arrives on your webhook — then links down to the specific endpoints underneath it.

If you already know you need address screening or xPub sync, skip ahead to the product. If you are still scoping — deciding whether to build deposit detection yourself — start here.

Start with the right building block

The products people reach for first, and what each one actually replaces. One API key, one request shape and one credit balance cover all of them — everything above runs on it from your first call.

You can combine them freely: most production integrations use address data plus events, then add transaction preparation or screening once the basics are live.

Address Latest

Retrieve blockchain data, balances, and transactions

Address History

Detailed blockchain history and transaction data for any address.

Block Data

Access to full transaction data on all transactions & addresses

Blockchain Events

Real-time notifications for multiple event types on top blockchains. Response under 100ms.

Verify Address

AML, sanctions and fraud screening for crypto addresses across 20+ blockchains.

HD Wallets Management

Sync and manage HD wallets, keys and addresses

AI Compatibility

60 MCP tools, a 47-command CLI and agent skills for Claude, Cursor and n8n.

What we support

Thirty-five-plus networks behind one request shape. EVM chains, UTXO chains, and the account-based outliers — Solana, XRP, Tezos, Kaspa — all answer the same endpoints with the same auth, the same pagination and the same error codes. Switching from Ethereum to Tron is a path parameter, not a new integration.

Every chain runs mainnet and testnet on the same key, so you build against a faucet and promote to production by changing one word. We run the nodes, absorb the reorgs and keep the archive data warm; you never operate infrastructure to read a balance.

Start with a guide

Working integrations you can run. Each guide goes end to end on the free tier against real chains, so you see what the workflow costs before you commit to it.

They are written the way an engineer evaluates: request, response, and the thing that breaks in production.

Where has Crypto APIs established its registration?

Which blockchains 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 mutiple 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 it happens one to go offline, there is always another one 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 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 is providing flexibility and is allowing 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 directly discuss it with one of our representatives by contacting our team.

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.

How can I pay for the service?

We accept payment methods such as debit and credit cards (Visa, MasterCard) by using our payment provider Stripe. We can also offer you an alternative way to pay for your subscription plan, such as wire transfers, pay with cryptocurrency or PayPal. For more information, contact our business development team at [email protected]

Are payments for Crypto APIs services recurring?

Yes, our service plans are subscription-based, with payments recurring automatically until customers cancel their subscriptions. Please note that upon cancellation, clients are responsible for covering the costs of the current payment term. The subscription will be 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 at [email protected] 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 subscriptions (yearly). If you believe your subscription qualifies for a discount, please contact our team right away!

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 synced addresses, HD wallets and blockchain event subscriptions — will be permanently deleted. Your keys and funds are never held by Crypto APIs, so nothing of yours is affected: the deletion covers the data we store on your behalf.

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.
