Blockchain APIs – Blockchain as a service (BaaS)

To develop an application that relies on one or more Blockchain protoocls, you need to hire Blockchain developers with experience in each of these Blockchain protocols, setup and secure the servers, sync the nodes, find a good and reliable library and integrate each Blockchain protocol separately.

Using Blockchain APIs, you can use +10 Blockchain protocols with one simple API. CryptoAPIs BaaS will give you the time to focus on building your product, save time and cost, drive innovation, accelerate business and reduce risk.

The problem

  • 100+ Blockchain protocols and counting, each with its own node, implementation and documentation
  • Libraries patches and upgrades are not always secure
  • Harder adoption for non Blockchain developers
  • Huge servers cost for having the full nodes of needed Blockchain protocols
  • Huge cost for having secure, 100% uptime and synced nodes
  • Huge cost for development needed to integrate needed Blockchain protocols
  • Often updates of both clients and libraries
  • Choosing the right framework and infrastructure

The solution

  • 0% commission!
  • 10+ Integrated Blockchain nodes (test & main) and more are coming
  • Browse the blockchain (historical data)
  • Create & Check wallets, balances, addresses and contracts
  • Create transactions or payment forwarding
  • Bech32, SegWit, xPub and HD support
  • Refund & Proof of ownership
  • Optimize and manage gas fees
  • Get a Webhook about certain events
  • Take care of private keys or leave it to us

Using Wallets

Get information for both normal and HD wallets.

Both HD Wallets and normal Wallets can be leveraged by the Address API, just by using their nameinstead of address. They can also be used with Events and with the Transaction API. In general, using a wallet instead of an address in an API will have the effect of batching the set of addresses contained in the wallet.

Blockchains are highly transactional systems. Many usage patterns require knowing when an event occurs: i.e., when a transaction is included into a block, or when an unconfirmed transaction is relayed through the network. Instead of requiring you to continuously poll resources, we provide push APIs to facilitate those use cases, and support both WebSockets and Webhooks.

Blockchains are highly transactional systems. Many usage patterns require knowing when an event occurs: i.e., when a transaction is included into a block, or when an unconfirmed transaction is relayed through the network. Instead of requiring you to continuously poll resources, we provide push APIs to facilitate those use cases, and support both WebSockets and Webhooks.

Payment Forwarding information

Get general information about Payment Forwarding

One of the well-known benefits of cryptocurrency is the ability to allow users to partake in online commerce without necessarily requiring extensive setup barriers, like registering new accounts. In that spirit, our Payment Forwarding API is the easiest way to accept—and consolidate—payments securely without forcing your users to create accounts and jump through unnecessary loops. It’s also a generic way to automatically transfer value from one address to another.

Webhook Notification information

Get general information about Webhook Notifications

Blockchains are highly transactional systems. Many usage patterns require knowing when an event occurs: i.e., when a transaction is included into a block, or when an unconfirmed transaction is relayed through the network. Instead of requiring you to continuously poll resources, we provide push APIs to facilitate those use cases, and support both WebSockets and Webhooks.

Webhook Notification information

Webhook Notification information Get general information about Webhook Notifications

Blockchains are highly transactional systems. Many usage patterns require knowing when an event occurs: i.e., when a transaction is included into a block, or when an unconfirmed transaction is relayed through the network. Instead of requiring you to continuously poll resources, we provide push APIs to facilitate those use cases, and support both WebSockets and Webhooks.

Payment Forwarding information

Get general information about Payment Forwarding

One of the well-known benefits of cryptocurrency is the ability to allow users to partake in online commerce without necessarily requiring extensive setup barriers, like registering new accounts. In that spirit, our Payment Forwarding API is the easiest way to accept—and consolidate—payments securely without forcing your users to create accounts and jump through unnecessary loops. It’s also a generic way to automatically transfer value from one address to another.

Webhook Notification information

Get general information about Webhook Notifications

Blockchains are highly transactional systems. Many usage patterns require knowing when an event occurs: i.e., when a transaction is included into a block, or when an unconfirmed transaction is relayed through the network. Instead of requiring you to continuously poll resources, we provide push APIs to facilitate those use cases, and support both WebSockets and Webhooks.

Blockchain APIs (BaaS) FAQ

What BaaS means?

BaaS means Blockchain as a service

What Blockchains does Crypto APIs support?

Crypto APIs support currently:

  • Bitcoin (testnet and mainnet)
  • Ethereum (rinkeby, ropsten and mainnet)
  • Bitcoin Cash (testnet and mainnet)
  • Litecoin (testnet and mainnet)
  • Dash (testnet and mainnet)
  • Doge (testnet and mainnet)

Expected soon:

  • Bitcoin SV (testnet and mainnet)
  • Zcash (testnet and mainnet)
  • Bitcoin Gold (testnet and mainnet)

What i can develop using BaaS?

All features supported by the different blockchain protocols could be done using Crypto APIs. The only difference is that Crypto APIs will save you a lot of time and cost.

Are the APIs endpoints unique for all Blockchain protocols?

Yes but not for all, for example all Bitcoin based protocols like Bitcoin Cash, Bitcoin SV, Litecoin, Dash, Doge, ZCash and BTG have same endpoints and you can change only one parameter (btc/ltc, etc.) in the request while Ethereum has different specifics as Blockchain, again the endpoints are very similar but they are not 100% the same.

How do you manage the private keys?

There is a common sentence in the crypto market: “Not your keys – Not your coins”.

Crypto APIs supports 3 ways to manage private keys:

  1. Use a wallet already generated by you or that you will generate in a more secure way, sign the
    transaction on your side and send it to us. This means we will never get the private key.
  2. Generate a wallet/address using our API, we will generate both public and private keys and
    will return them to you. We will NOT save the private key on our side, it’s up to you how you will
    store it, but in case you lose it there is no way to use any backup! Every time you want us to do
    something with this wallet you should sign it using your private key and send it signed. In this
    case you can manage the wallet in any other way as well.
  3. Generate a wallet using our API with a password, in this case we encrypt the private key with
    this password and save it on our side. We use 4 levels for securing the password. In case of
    hacks or similar, no one can use the private key without your password. When you want to
    operate with the wallet you need to use the password to be able to decrypt the private key and
    use it and in case you lose the password you will lose access to the wallet as we save only the
    encrypted version of the private key. We allow you to download the encrypted private keys at
    any time.

What is payment forwarding?

Payment Forwarding is a good option to move a certain % of all funds from a wallet A (hot) to wallet B (warm or cold) automatically once funds are received.

What is Webhook and how it helps me?

Webhook is a call back notification we send in case you are subscribed, you can subscribe for new block, confirmed transaction, address and transaction confirmations, see here: https://docs.cryptoapis.io/rest-apis/blockchain-as-a-service-apis/btc/index#types-of-events

Does Crypto APIs support inserting meta data (OP_RETURN) in the transactions?

Yes, you can insert meta data in the transactions.

Does Crypto APIs support Bech32, SegWit, xPub and HD Wallets?

Yes, we support Bech32, SegWit, xPub and HD Wallets.

Does Crypto APIs support replacing a transaction?

Yes, in case you make a transaction and you mark the parameter “replaceable” as true and the transaction is not mined. You can send a new request and replace it.

Do you take any fees as percentage from the funds?

No, we don’t take any % from your funds. Our fees are only the subscription you pay for using our product.

Do you store the whole Blockchain node in a database?

Yes, we store most of the data in our database to be able to deliver it much faster.

Do you support ERC-20 Tokens?

Yes, we support all available tokens in Ethereum.

Do you give information about gas and fees?

Yes, we provide such endpoints like:

1. https://docs.cryptoapis.io/rest-apis/blockchain-as-a-service-apis/eth/index#eth-transaction-gas-price-endpoint
2. https://docs.cryptoapis.io/rest-apis/blockchain-as-a-service-apis/eth/index#eth-estimate-transaction-gas-limit-endpoint
