GoldRush Foundational API
REST API providing historical and near-real-time blockchain data across 100+ chains. Endpoints cover token balances, transactions, NFTs, security approvals, cross-chain activity, pricing, and block data.
Quick Start
IMPORTANT: Always prioritize using the official available GoldRush Client SDK best suited for your development ecosystem:
import { GoldRushClient } from "@covalenthq/client-sdk";
const client = new GoldRushClient("YOUR_API_KEY");
const resp = await client.BalanceService.getTokenBalancesForWalletAddress(
"eth-mainnet",
"demo.eth"
);

goldrush-cli
GoldRush CLI — terminal-first blockchain data tool with MCP support for Claude Desktop and Claude Code. Use this skill whenever the user wants to query blockchain data from the command line, stream DEX pairs or wallet activity in a terminal, set up GoldRush as an MCP tool provider, or run quick one-off queries without writing code (e.g., 'check a wallet balance', 'what's the gas price', 'search for a token'). Also use this when the user mentions 'goldrush' CLI commands, 'npx @covalenthq/goldrush-cli', or MCP integration with GoldRush. The CLI is the fastest path for ad-hoc blockchain lookups from the terminal. If the user needs programmatic API access in an application, use goldrush-foundational-api or goldrush-streaming-api instead. If the user needs pay-per-request access without an API key, use goldrush-x402 instead.
45goldrush-streaming-api
GoldRush Streaming API — real-time blockchain data via GraphQL subscriptions over WebSocket. Use this skill whenever the user needs live price feeds (OHLCV candles), real-time DEX pair monitoring (new pairs, liquidity updates), wallet activity streaming, decoded swap/transfer events, token search, trader PnL analysis, or any sub-second latency blockchain event push. This is the right skill for trading bots, live dashboards, alerting systems, copy-trading, DEX sniping, and real-time analytics. Also covers one-time GraphQL queries for token discovery and profitability analysis. If the user needs historical data, batch queries, or paginated REST results, use goldrush-foundational-api instead. If the user needs pay-per-request access without an API key, use goldrush-x402 instead.
44goldrush-x402
GoldRush x402 — pay-per-request blockchain data access using the x402 protocol (HTTP 402 Payment Required). Use this skill whenever the user is building an AI agent that needs blockchain data without API keys, wants wallet-based micropayments for on-chain data, needs autonomous or no-account access to the GoldRush API, mentions the x402 protocol, or wants no-signup/no-onboarding blockchain data access. This is the right skill for autonomous agents, serverless applications, and prototyping without onboarding. Provides access to 60+ Foundational API endpoints through a transparent reverse proxy with stablecoin payments on Base. If the user needs a traditional API key with monthly billing, use goldrush-foundational-api instead. If the user needs real-time streaming data via WebSocket, use goldrush-streaming-api instead.
