Use the Alchemy CLI (`@alchemy/cli`) for live blockchain queries, admin, and on-machine automation across EVM JSON-RPC, Token, Transfers, Prices, Portfolio, Simulation, Solana RPC/DAS/gRPC, Sui gRPC, Webhooks, and app management. Preferred runtime path when CLI is installed locally. For NFT marketplace data, listings, or Seaport fulfillment, use `opensea-api` / `opensea-marketplace`. For shipped app code, use `alchemy-api` (with API key) or `alchemy-agentic-gateway` (without).
