Notice: This repository is experimental and subject to change without notice. By using the features and skills in this repository, you agree to Alchemy's Terms of Service and Privacy Policy . A skill that lets agents easily access Alchemy's developer platform. If ALCHEMY_API_KEY is set in the environment, requests go directly to standard Alchemy endpoints — no wallet or payment setup needed. Otherwise, the gateway authenticates callers with SIWE (Sign-In With Ethereum) or SIWS (Sign-In With Solana) tokens and handles payments via the x402 protocol using USDC. If ALCHEMY_API_KEY is set in the environment, use standard Alchemy endpoints directly: No wallet setup, SIWE/SIWS auth, or x402 payment is needed. Just make requests with the API key in the URL. Skip the Wallet Gate and all x402-related steps below.
