EVM JSON-RPC

Standard Ethereum JSON-RPC. Works with ethers.js, viem, web3.py, Foundry and Hardhat.
HTTPShttps://rpc.gscscan.com
curl -X POST https://rpc.gscscan.com \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"eth_blockNumber","params":[]}'
import { ethers } from "ethers";
const p = new ethers.JsonRpcProvider("https://rpc.gscscan.com");
const n = await p.getBlockNumber();
console.log(n);

Etherscan-compatible API

Drop-in replacement for the Etherscan API. Use https://gscscan.com/api as the apiURL in Hardhat, Foundry, ethers or any Etherscan-based tool. No API key required.
RESThttps://gscscan.com/api?module=<module>&action=<action>
# account balance
curl "https://gscscan.com/api?module=account&action=balance&address=0x9c6f…6784"
# latest block reward
curl "https://gscscan.com/api?module=block&action=getblockreward&blockno=29000"
# native coin supply
curl "https://gscscan.com/api?module=stats&action=ethsupply"
# event logs / token / contract abi
curl "https://gscscan.com/api?module=logs&action=getLogs&fromBlock=1&toBlock=latest&address=0x…"
Etherscan-style JSON-RPC proxy (eth_* methods over a single HTTPS endpoint):
JSON-RPChttps://gscscan.com/api/eth-rpc
Contract verification with Hardhat:
// hardhat.config.js
etherscan: {
  apiKey: { gicomni: "no-key-needed" },
  customChains: [{
    network: "gicomni",
    chainId: 7777,
    urls: {
      apiURL: "https://gscscan.com/api",
      browserURL: "https://gscscan.com"
    }
  }]
}
…or with Foundry:
forge verify-contract <addr> src/MyToken.sol:MyToken \
  --verifier blockscout \
  --verifier-url https://gscscan.com/api/

Cosmos REST (LCD)

Cosmos SDK REST gateway — staking, bank, distribution and governance modules.
HTTPShttps://api.gscscan.com
curl https://api.gscscan.com/cosmos/staking/v1beta1/validators
curl https://api.gscscan.com/cosmos/bank/v1beta1/supply
curl https://api.gscscan.com/cosmos/staking/v1beta1/pool

Tendermint RPC

CometBFT consensus RPC — blocks, validators, network and node status.
curl https://gscscan.com/cometbft/status
curl https://gscscan.com/cometbft/validators
curl "https://gscscan.com/cometbft/block?height=1"

Explorer API

The explorer exposes a REST API for blocks, transactions, addresses and tokens. Full interactive reference below.
RESThttps://gscscan.com/api/v2
curl https://gscscan.com/api/v2/stats
curl "https://gscscan.com/api/v2/blocks?type=block"
curl https://gscscan.com/api/v2/transactions

AI / MCP server

GIC OMNI exposes a Model Context Protocol server so any AI assistant (Claude Desktop, IDEs, agents) can query the chain directly — blocks, transactions, addresses, validators and dual-VM address conversion. Streamable HTTP, no key required.
MCPhttps://gscscan.com/mcp
Tools: get_chain_status · get_latest_blocks · get_block · get_transaction · get_address · convert_address · get_validators · search
Add it to an MCP client (e.g. Claude Desktop):
{
  "mcpServers": {
    "gic-omni": {
      "type": "http",
      "url": "https://gscscan.com/mcp"
    }
  }
}
…or for stdio-only clients, bridge with mcp-remote:
npx mcp-remote https://gscscan.com/mcp
