Enhanced Usability with Indexed Methods
In addition to the standard JSON-RPC methods, our service offers a small set of specialized indexed methods designed to enhance usability and streamline data retrieval. By leveraging an index node, users can efficiently query Bitcoin balances and transaction histories directly by address. This eliminates the need for complex manual aggregation or blockchain scanning.
Our indexing capability simplifies interactions with the Bitcoin network, allowing developers to access critical account data with ease. This approach improves performance and reduces the overhead typically associated with raw blockchain queries.
The following example demonstrates how to query a Bitcoin address using our indexed method:
curl https://api.chain-rpc.online/bitcoin-index/address/34rng4QwB5pHUbGDJw1JxjLwgEU8TQuEqv \
-H "X-API-Key: test"
