GoldRush API
Overview
GoldRush by Covalent provides blockchain data across 100+ chains through a unified REST API, real-time WebSocket streams, a CLI, and an x402 pay-per-request proxy. This skill enables AI agents to query wallet balances, token prices, transaction history, NFT holdings, and DEX pair data without building chain-specific integrations.
When to Use This Skill
- Retrieving wallet token balances or total portfolio value across any chain
- Fetching transaction history or decoded event logs for an address
- Getting current or historical token prices (USD or native)
- Monitoring DEX pairs, liquidity events, and real-time OHLCV candles via WebSocket
- Building block explorers, portfolio dashboards, tax tools, or DeFi analytics
- Accessing on-chain data with no signup via x402 pay-per-request
How It Works
Step 1: Get credentials
Sign up at https://goldrush.dev for a free API key. For agent-native no-signup access, use the x402 proxy instead.
Step 2: Set your API key
export GOLDRUSH_API_KEY="your_api_key_here"
Step 3: Query data
REST API (most endpoints):
curl -H "Authorization: Bearer $GOLDRUSH_API_KEY" "https://api.covalenthq.com/v1/eth-mainnet/address/0xADDRESS/balances_v2/"
CLI (quick terminal queries):
npx @covalenthq/goldrush-cli balances --chain eth-mainnet --address 0xADDRESS
SDK (in code):
import GoldRushClient from "@covalenthq/client-sdk";
const client = new GoldRushClient(process.env.GOLDRUSH_API_KEY);
const resp = await client.BalanceService.getTokenBalancesForWalletAddress(
,
);
