ARQMA Blockchain Explorer API

This explorer provides an API for getting details about transactions, blocks, mempool, network stats, and more. Additionally it provides a way to prove transactions and search for transactions belonging to a given address.

api/transaction/<tx_hash>

curl  -w "\n" -X GET "https://explorer.arqma.com/api/transaction/ab6481288a5f72f9a1cc329cd85f0d686b7fd85b2abcca8e93eecb5e6a8bb038"

api/outputs?txhash=<tx_hash>&address=<address>&viewkey=<viewkey>&txprove=<0|1>

For txprove=0 we check which outputs belong to given address and corresponding viewkey. For txprove=1 we use to prove to the recipient that we sent them founds. For this, we use recipient's address and our tx private key as a viewkey value, i.e., viewkey=<tx_private_key>

Checking outputs:

Proving transfer:

We use recipient's address (i.e. not our address from which we sent ARQ to recipient). For the viewkey, we use tx_private_key (although the GET variable is still called viewkey) that we obtained by sending this txs.

api number is store as uint32_t. In this case 65536 represents major version 1 and minor version 0. In JavaScript to get these numbers, one can do as follows:

var api_major = response.data.api >> 16;
    var api_minor = response.data.api & 0xffff;
