## API

This API is available if the node is running public http-access. Set the constant HTTP_HOSTING_PORT.

#### Getting the current status of the blockchain
http://194.1.237.94/GetCurrentInfo?Diagram=0

Result:
* MaxNumBlockDB - the maximum block number stored in the database (the current height of the blockchain)
* CurBlockNum - new block to create
* MaxAccID - current maximum account number
* MaxDappsID  - current maximum Dapp number
* VersionNum - version of the program on which the node works


An example of the result:
```
{"result":1,"VersionNum":706,"MaxNumBlockDB":12371158,"CurBlockNum":12371166,"MaxAccID":187783,"MaxDappsID":20,"FIRST_TIME_BLOCK":1530446400000}
```
