Wire Alchemy into application code (server, backend, dApp, script) using a standard API key. Preferred app-integration path for normal server/backend usage. Covers EVM JSON-RPC, WebSocket subscriptions, Simulation, Webhooks/Notify, Solana RPC, Solana DAS, Solana Yellowstone gRPC, Sui gRPC, Wallets/Account Kit, Account Abstraction, and operational topics. Requires `$ALCHEMY_API_KEY`. For app code without an API key (autonomous agent paying per-request, or explicit x402/MPP), use `alchemy-agentic-gateway` instead.
Wire Alchemy into application code without an API key, using the x402 or MPP gateway with wallet-based auth (SIWE/SIWS) and per-request payments (USDC via x402, or USDC/credit-card via MPP). Specialized app-integration path. Use when the user is building application code AND no API key is available, or they're an autonomous agent that needs to pay for itself, or they explicitly want x402/MPP. For normal app code with an Alchemy API key, use `alchemy-api`.
Query blockchain data using the allium CLI. Token prices, wallet balances, transactions, PnL, historical holdings, and SQL analytics across 80+ chains. Supports API key, x402 micropayments, and Tempo auth. Use when user asks about crypto prices, wallet balances, on-chain analytics, or blockchain data. Always use this skill for any Allium data queries, blockchain lookups, or on-chain analysis tasks.
