I find your product very easy to use, I'm sorry that I've wasted a couple of days trying other similar API's after failing to manually develop what I needed myself. I chose Crypto APIs because I found it very easy to set up and start working with it.

Do you take any commissions?

No, we don’t charge any commission. The only fee is the monthly subscription of your package in case you don’t use Free Package.

How do you count requests and charge them?

When the end point returns one item like getting a price of a coin, we charge one request. When results are more than 50 like getting all transactions in one block, we charge 1 request per 50 results.

How I can be always updated?

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. You are able to consolidate Bitcoin, Ethereum, Litecoin and other coins into one main wallet.

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:

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:

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 ERC20 Tokens?

Yes, we support all available tokens in Ethereum.

Do you give information about gas and fees?

Yes, we provide such endpoints like: 1. 2. 3.
This is unique feature that is loved by developers. 

What Exchanges do you support?

We get our data from top crypto exchanges, you can get the full live list using this endpoint: Some of them are: Binance, Coinbase Pro, Bitstamp, Bittrex , Poloniex, Kraken, OKEx, Gemini, Huobi, Bitfinex, etc.

What Market Data do you offer?

  • Exchanges: List of exchanges with their logos, website, volume and more details.
  • Crypto Currencies: List of all coins and tokens which are listed in any of the supported exchanges with their current rate.
  • FIAT Currencies: List of all FIAT currencies with their current rate.
  • Markets: All supported markets.
  • Exchange Rates (Live and Historical): An average exchange rate based on trades in the different exchanges and exchange rates per exchange.
  • OHLCV (Live and Historical): Open, High, Low, Close, Volume – per exchange and per asset.
  • Trades (Live and Historical): Trades by Asset, Exchange, Pair and Symbol.
  • Quotes (Live and Historical): Quotes by Asset, Exchange, Pair and Symbol.
  • Candles: (Live and Historical).
  • Order Books (Live and Historical).

How often do you calculate the exchange rate?

The exchange rates are updated every 1 minute.

How old is your historical data?

For the exchange rates, we have the full data, the oldest one is for BTC (07/28/2010). For Quotes, Trades, OHLCV etc. It depends on the exchange start date and when we started collecting data. You can get more information about that from our APIs.

Why do you use unique IDs instead of symbols?

Most APIs use symbols like BTC for Bitcoin while we support unique IDs, the reason is that there are no standards in Crypto Market and BTC could be an ERC-20 token. To escape problems with duplicated symbols we decided to use unique IDs.

To make it easier for our clients who are changing their provider, we are working on an update where we will support both.

I need a large volume of historical market data. What's the best way to get that?

All of our historical market data is available over API and that is the preferred delivery method for many of our customers. If you prefer a custom one-time export of historical data this can be arranged using the full scope of our historical records dating back to 2010.

Are cryptocurrency and exchange logo image assets available via API?

Yes, our metadata endpoints include hosted logo assets as base64 format, most of them are SVG so you can resize them based on your needs.

Trading APIs provides one Unified API that has integrated multiple crypto exchanges.

Users are able to link multiple exchange accounts to their profiles, collect data and execute their portfolio management trades from a single point.
