Get Account Transactions

Getting Account Transactions
The Stacks API provides an endpoint for getting all transactions related to a principal, which can be a Stacks address or a contract identifier.
Contract identifiers are formatted deployer_address.contract-name
e.g. SP2H8PY27SEZ03MWRKS5XABZYQN17ETGQS3527SA5.newyorkcitycoin-core-v1
The limit parameter can fetch a maximum of 50 transactions at a time, and the offset parameter allows you to set the index for the first transaction to fetch.
Using the total value from the initial result, a simple do...while loop can help iterate over and collect all transactions for an address.

Filtering Transactions
With the full set of transactions for an address, the results can then easily be filtered into a new array with useful data.
MIA Mining
Filters for all MIA mining transactions for the specified address.
1
// get all MIA mining tx for address
2
let address = 'SP3CK642B6119EVC6CT550PW5EZZ1AJW661ZMQTYD';
3
let miningTxs = [];
4
let txs = getAccountTxs(address);
5
txs.map(tx => {
6
  if (tx.tx_type === 'contract_call') {
7
    if (tx.contract_call.contract_id === `SP466FNC0P7JWTNM2R9T199QRZN1MYEDTAR0KP27.miamicoin-core-v1` && tx.tx_status === 'success') {
