Using the API​

Chainz API​

# Get address balance
curl "https://chainz.cryptoid.info/marks/api.dws?q=getbalance&a=<address>"

# Get block info
curl "https://chainz.cryptoid.info/marks/api.dws?q=getblockcount"

# Get transaction
curl "https://chainz.cryptoid.info/marks/api.dws?q=txinfo&t=<txid>"

Common Queries​

Running Your Own Explorer​

Using bitmark-api​

The bitmark-api project provides a local explorer with REST API.

# Clone and install
git clone https://github.com/project-bitmark/bitmark-api.git
cd bitmark-api
npm install

# Configure
cp .env.example .env
# Edit .env with your bitmarkd RPC credentials

# Start
npm start

Endpoints:

  • http://localhost:3000/ - Web interface
  • http://localhost:3000/api/status - Sync status
  • http://localhost:3000/api/block/:height - Block info
  • http://localhost:3000/api/tx/:txid - Transaction info

Explorer Data​

Network Statistics​

Most explorers provide:

  • Block height: Current chain height
  • Difficulty: Per-algorithm difficulty
  • Hashrate: Estimated network hashrate
  • Supply: Circulating supply
  • Transactions: Transaction volume

Rich List​

View addresses with largest balances:

Rank | Address        | Balance    | % Supply
-----|----------------|------------|----------
1    | bTop1Address.. | 500,000    | 1.8%
2    | bTop2Address.. | 350,000    | 1.3%
3    | bTop3Address.. | 200,000    | 0.7%

Marks on Explorers​

Viewing Mark Transactions​

Mark transactions are visible on explorers as OP_RETURN data:

OP_RETURN: 4d524b01018823a419a50848d314c84eb556cdf8812c212a2b225ef1e38b9855ea84faa9e9
           │    │ │ │
           │    │ │ └─ Reference hash (32 bytes)
           │    │ └─── Type: 0x01 (URL)
           │    └───── Version: 0x01
           └────────── Magic: "MRK"

Searching for Marks​

On bitmark-api explorer:

GET /api/marks?hash=<reference_hash>
GET /api/marks?type=1&limit=100

Privacy Considerations​

When using public explorers:

  1. IP logging: Your IP may be logged
  2. Address linking: Multiple lookups can be correlated
  3. Timing analysis: Access patterns are visible

For privacy-sensitive operations:

  • Run your own explorer
  • Use Tor browser
  • Avoid repeated address lookups
