Alchemy

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, Token API, NFT API, Transfers API, Prices API, Portfolio API, Simulation, Webhooks, Solana RPC, Solana DAS, Solana Yellowstone gRPC, Sui gRPC, Wallets/Account Kit, and operational topics. Requires `$ALCHEMY_API_KEY`. For live agent work in this session (querying, admin, local automation), use `alchemy-cli` (preferred) or `alchemy-mcp` instead. For app code without an API key (autonomous agent paying per-request, or explicit x402/MPP), use `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 API key, use `alchemy-api`. For live agent work in this session (querying, admin, automation), use `alchemy-cli` (preferred) or `alchemy-mcp`.
