One data layer, four ways to query it

The REST API, CLI, MCP server and x402 all read the same indexed, decoded data. Start with whichever fits your workflow, for you or your agent, and switch later without changing your data model.

  • REST API and SDKs

    Decoded JSON over HTTPS, with TypeScript and Python SDKs. Balances, transactions, NFTs, prices and DEX data from 100+ chains.

    GET /v1/{chainName}/address/{walletAddress}/balances_v2/
    Read the API docs

  • CLI

    Query any chain from your terminal: balances, transfers, NFTs, new DEX pairs, top traders, gas and live wallet watching. Runs with npx, nothing to install.

    npx @covalenthq/goldrush-cli
    CLI reference

  • MCP Server and Agent Skills

    37 MCP tools in v3.0.9: 28 for wallet, transaction, NFT, price and Bitcoin data, plus 9 protocol analytics tools for metrics, breakdowns and rankings. Works in Claude Code, Cursor, Codex and Windsurf.

    claude mcp add goldrush -- npx -y @covalenthq/goldrush-mcp-server@latest
    Agent integrations

  • x402 pay-per-request

    No signup and no API key. The agent gets an HTTP 402, pays onchain and retries with the receipt. Metered per call.
