Blockchain APIs – Blockchain as a service (BaaS)

To develop an application that relies on one or more Blockchain protocols, 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

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.

Blockchain APIs (BaaS) FAQ

What BaaS means?

BaaS means Blockchain as a service. Blockchain APIs – Get all the needed information about a blockchain, its blocks and the transactions contained in these blocks.

What Blockchains does Crypto APIs support?

Crypto APIs support currently:

  • Bitcoin (testnet and mainnet)
  • Ethereum (rinkeby, ropsten and mainnet)
  • Ethereum Classic (mainnet)
  • Bitcoin Cash (testnet and mainnet)
  • Litecoin (testnet and mainnet)
  • Dash (testnet and mainnet)
  • Doge (testnet and mainnet)
  • Tether (Omni Layer)
  • Tether (ERC-20)

Expected soon:

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

What can I develop using BaaS/Blockchain APIs?

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. Here is a detailed article on how to add meta data to your Bitcoin transaction: https://cryptoapis.io/blog/metadata-to-your-bitcoin-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 Blockchain as a Service/Blockchain APIs.

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 3. https://docs.cryptoapis.io/rest-apis/blockchain-as-a-service-apis/btc/index#btc-transactions-fee-endpoint
