Key Features

​
JSON-RPC API

Query transactions using JSON-RPC 2.0 methods: 
const response = await fetch('https://api.solixdb.xyz/v1/rpc', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'x-api-key': 'YOUR_API_KEY'
  },
  body: JSON.stringify({
    jsonrpc: '2.0',
    id: 1,
    method: 'getProtocolStats',
    params: [{
      protocolName: 'drift_v2',
      blockTime: {
        gte: 1735689600,
        lte: 1738368000
      }
    }]
  })
});

const data = await response.json();
console.log('Protocol Stats:', data.result);

​
SQL Queries

Execute SQL queries directly (automatic LIMIT injection): 
const response = await fetch('https://api.solixdb.xyz/v1/query', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'x-api-key': 'YOUR_API_KEY'
  },
  body: JSON.stringify({
    query: 'SELECT * FROM transactions WHERE protocol_name = \'drift_v2\' LIMIT 10',
    format: 'json'
  })
});

const data = await response.json();
console.log('Results:', data.data);
