Alchemy Agentic Gateway (x402 / MPP)

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 specialized app-integration skill for using Alchemy's developer platform from application code without a standard API key. Authentication is wallet-based (SIWE for EVM, SIWS for Solana). Each request is paid per-call with USDC (x402) or USDC/credit-card (MPP).

When to use this skill

Use agentic-gateway when all of the following are true:

• The user is wiring Alchemy into application code (server, backend, dApp, worker, script) that runs outside the current agent session
• AND at least one of:
  • No Alchemy API key is available
  • The user is an autonomous agent that needs to pay for itself (per-request, no upfront key)
  • The user explicitly wants x402 or MPP
  • No other runtime path exists and they intentionally choose the gateway

This is a specialized app-integration path. The default app path is alchemy-api with an API key.
