## API and utils

### Importing in your project file

```js
var BlockBee = require('@blockbee/api')
```

### Getting service info

```js
// Get general service information
const info = await BlockBee.getInfo()

// Get specific coin information
const coinInfo = await BlockBee.getInfo('btc')
```

#### Where:
* The first call gets general service information
* The second call gets information for a specific coin (e.g. 'btc', 'eth', 'erc20_usdt', ...)

> Response contains service information and coin-specific details when a coin parameter is provided.

### Generating a new Address

```js
const bb = new BlockBee(coin, myAddress, callbackUrl, params, blockbeeParams, apiKey)

const address = await bb.getAddress()
```

#### Where:

* `coin` is the coin you wish to use, from BlockBee's supported currencies (e.g 'btc', 'eth', 'erc20_usdt', ...).
* `myAddress` is your own crypto address, where your funds will be sent to. It's optional, you can leave it empty (e.g ``''``) if you are setting it up in BlockBee's [dashboard](https://dash.blockbee.io/).
* `callbackUrl` is the URL that will be called upon payment.
* `params` is any parameter you wish to send to identify the payment, such as `{orderId: 1234}`.
* `blockbeeParams` parameters that will be passed to BlockBee. Check our [API Reference](https://docs.blockbee.io/api/checkoutrequest) for more information.
* `apiKey` is the API Key provided by BlockBee's [dashboard](https://dash.blockbee.io/).
* `address` is the newly generated address, that you will show your users in order to receive payments.

#### Response sample: 

```json
{
  "address_in": "14PqCsA7KMgseZMPwg6mJy754MtQkrgszu",
  "address_out": "1H6ZZpRmMnrw8ytepV3BYwMjYYnEkWDqVP (single address)\n\n{1H6ZZpRmMnrw8ytepV3BYwMjYYnEkWDqVP: 0.70, 1PE5U4temq1rFzseHHGE2L8smwHCyRbkx3: 0.30} (multiple addresses)\n",
  "callback_url": "https://example.com/invoice/1234?payment_id=5678",
  "priority": "default",
  "minimum_transaction_coin": 0.008,
  "status": "success"
}
```

#### Getting notified when the user pays

> Once your customer makes a payment, BlockBee will send a callback to your `callbackUrl`. This callback information is by default in ``GET`` but you can se it to ``POST`` by setting ``post: 1`` in ``blockbeeParams``. The parameters sent by BlockBee in this callback can be consulted here: https://docs.blockbee.io/#operation/confirmedcallbackget

### Checking the logs of a request

```js
const bb = new BlockBee(coin, myAddress, callbackUrl, params, blockbeeParams, apiKey)

const data = await bb.checkLogs()
```

#### Response sample:

```json
{
  "status": "success",
  "callback_url": "https://example.com/?order_id=1235",
  "address_in": "0x58e90D31530A5566dA97e34205730323873eb88B",
  "address_out": "0xA6B78B56ee062185E405a1DDDD18cE8fcBC4395d",
  "notify_pending": false,
  "notify_confirmations": 1,
  "priority": "default",
  "callbacks": []
}
```

All the `data` returned in the response can be checked here: https://docs.blockbee.io/#operation/logs

### Generating a QR code

```js
const bb = new BlockBee(coin, myAddress, callbackUrl, params, blockbeeParams, apiKey)

const qrCode = await bb.getQrcode(value, size)
```

#### Where:

* ``value`` is the value requested to the user in the coin to which the request was done. **Optional**, can be empty if you don't wish to add the value to the QR Code.
* ``size`` Size of the QR Code image in pixels. Optional, leave empty to use the default size of 512.

> Response is an object with `qr_code` (base64 encoded image data) and `payment_uri` (the value encoded in the QR), see https://docs.blockbee.io/#operation/qrcode for more information.

#### Usage
```jsx
<img src={`data:image/png;base64,${qr_code}`}/>
```

### Estimating transaction fees

```js
const fees = await BlockBee.getEstimate(coin, apiKey, addresses, priority)
```
#### Where:

* ``coin`` is the coin you wish to check, from BlockBee's supported currencies (e.g `btc`, `eth`, `erc20_usdt`, ...)
* ``apiKey`` is the API Key provided by BlockBee's [dashboard](https://dash.blockbee.io/).
* ``addresses`` The number of addresses to forward the funds to. Optional, defaults to 1.
* ``priority`` Confirmation priority, (check [this](https://support.blockbee.io/article/how-the-priority-parameter-works) article to learn more about it). Optional, defaults to ``default``.

> Response is an object with ``estimated_cost`` and ``estimated_cost_usd``, see https://docs.blockbee.io/#operation/estimate for more information.

#### Response sample:

```json
{
  "status": "success",
  "estimated_cost": "0.00637010",
  "estimated_cost_currency": {
    "AED": "0.03",
    "AUD": "0.01",
    "BGN": "0.01",
    "BRL": "0.04"
  }
}
```

### Converting between coins and fiat

```js
const conversion = await BlockBee.getConvert(coin, value, from, apiKey)
```
#### Where:

* ``value`` value to convert in `from`.
* ``from`` currency to convert from, FIAT or crypto.
* ``apiKey`` is the API Key provided by BlockBee's [dashboard](https://dash.blockbee.io/).

> Response is an object with ``value_coin`` and ``exchange_rate``, see https://docs.blockbee.io/#operation/convert for more information.

#### Response sample:

{ 
  "status": "success", 
  "value_coin": "241.126", 
  "exchange_rate": "0.803753"
}
```

### Getting supported coins

```js
const supportedCoins = await BlockBee.getSupportedCoins(apiKey)
```

#### Where:
* ``apiKey`` is the API Key provided by BlockBee's [dashboard](https://dash.blockbee.io/).

> Response is an array with all supported coins.

#### Response sample:

```js
const paymentRequest = await BlockBee.paymentRequest(redirectUrl, notifyUrl, value, apiKey, params, bbParams)
```

#### Where:

* ``redirectUrl`` URL in your platform, where the user will be redirected to following the payment. Should be able to process the payment using the `success_token`, if you wish to use this URL to confirm payment.
