Alchemy
Alchemy Agentic Gateway — access Alchemy's blockchain developer platform (Node JSON-RPC, Token API, Transfers API, Simulation API, NFT API v3, Portfolio API, Prices API) without an API key, using wallet-based auth (SIWE for EVM, SIWS for Solana) and per-request USDC payments via the x402 protocol.
Routability
