Alchemy Skills

Agent Skills for integrating Alchemy APIs into AI-powered applications. This repo contains public skills for using Alchemy with the official CLI, API key, agentic gateway, and Codex plugin.

Skills

skills/alchemy-cli

CLI-first skill for agents with @alchemy/cli installed. Maps the Alchemy API surfaces to alchemy <command> invocations with structured JSON output.

• Auth: CLI manages auth internally (API key, access key, x402 wallet)
• Setup: npm i -g @alchemy/cli
• Entry point: skills/alchemy-cli/SKILL.md

skills/alchemy-api

Traditional API key-based access to all Alchemy products: EVM JSON-RPC, Token API, NFT API, Prices API, Portfolio API, Webhooks, Solana, and more.

• Auth: API key in URL or header
• Setup: Create a free key at dashboard.alchemy.com
• Entry point: skills/alchemy-api/SKILL.md

skills/agentic-gateway

Lets agents easily access Alchemy's developer platform. Supports three access methods: API key, x402 protocol (USDC payments), or MPP protocol (Tempo/Stripe payments). Prompts the user to choose their preferred protocol.

• Auth: API key, or SIWE/SIWS token + payment (x402 or MPP)
• Protocols: x402 (@alchemy/x402 + @x402/fetch) or MPP (mppx + Tempo/Stripe)
• Setup: API key, or generate a wallet and fund it with USDC
• Entry point: skills/agentic-gateway/SKILL.md

skills/alchemy-codex

Codex-facing router skill for users who know they want to build with Alchemy but have not yet chosen between a standard API key flow and the Alchemy gateway flow.

• Auth: Routes to the correct auth path before implementation
• Setup: No separate setup; delegates to the chosen Alchemy skill
• Entry point: skills/alchemy-codex/SKILL.md

Scenario	Skill
I have @alchemy/cli installed	alchemy-cli
I have an Alchemy API key	alchemy-api
I'm building a traditional server or dApp	alchemy-api
I'm an agent that needs easy access to Alchemy's developer platform	agentic-gateway
I need API method details (params, responses)	alchemy-api (then cross-ref gateway URLs)
I need SIWE auth or x402/MPP payment setup	agentic-gateway
I want to use Alchemy in Codex but have not chosen an auth path yet	alchemy-codex
