Alchemy Codex

Use this skill when the user wants to build with Alchemy in Codex but has not yet chosen how requests should be authenticated.
This skill routes to:
  • alchemy-api
    for standard API key-based access to Alchemy JSON-RPC, Data APIs, Webhooks, and Wallets
  • agentic-gateway
    for gateway-based access using an API key or wallet-based payment flows

Required first question

Before making a network call or implementation choice, ask:
Do you want to use an existing Alchemy API key, or should I use the agentic gateway flow instead?
Then route as follows:
  • If the user chooses an API key, switch to
    alchemy-api
  • If the user chooses the gateway flow, switch to
    agentic-gateway

Use this skill for

  • broad Alchemy integration requests where auth is still undecided
  • onboarding a developer to the right Alchemy access path
  • routing requests that mention Alchemy generally rather than a specific API surface

Typical tasks after routing

  • JSON-RPC reads and writes
  • Token, NFT, Transfers, Prices, and Portfolio APIs
  • transaction simulation and traces
  • Webhooks / Notify setup
  • Account Kit and wallet infrastructure
  • agentic gateway access via x402 or MPP
