Groestlcoin (GRS) API Documentation

Groestlcoin

Groestlcoin (GRS) is a proof-of-work payments blockchain with a Bitcoin-derived architecture, and SegWit became a protocol upgrade on the network in 2017. Transactions use Script and a UTXO model, while Groestlcoin Core full nodes validate proof-of-work blocks and transactions and maintain the blockchain, mempool, and current UTXO set. That architecture keeps blocks, raw transactions, addresses, scripts, and unspent outputs aligned with Bitcoin-family integration patterns while Groestlcoin retains its own proof-of-work rules.

Groestlcoin API Methods and Endpoints

NOWNodes exposes Groestlcoin's interface, plus a few others, depending on what your integration needs: JSON-RPC for reading chain state and broadcasting transactions, and Blockbook for indexed address, balance, transaction, and block lookups. Archive mode extends any of these to historical states and data beyond standard retention.

Browse the interfaces below for endpoint details, request parameters, response formats, and integration examples. Create an API key, select Mainnet or Testnet, choose the required interface, and start sending requests from your application.
