Alchemy API (with API Key)
Reference and integration guide for wiring Alchemy APIs into application code using a standard API key. This file alone is enough to ship a basic integration; the references/ directory contains deeper coverage of every product surface.
When to use this skill
Use alchemy-api 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
- They have, or are willing to create, an Alchemy API key (free at dashboard.alchemy.com)
This is the preferred app-integration path for normal server/backend usage.
When to use a different skill

agentic-gateway
Wire Alchemy into application code without an API key, using the x402 or MPP gateway with wallet-based auth (SIWE/SIWS) and per-request payments (USDC via x402, or USDC/credit-card via MPP). Specialized app-integration path. Use when the user is building application code AND no API key is available, or they're an autonomous agent that needs to pay for itself, or they explicitly want x402/MPP. For normal app code with an API key, use `alchemy-api`. For live agent work in this session (querying, admin, automation), use `alchemy-cli` (preferred) or `alchemy-mcp`.
401alchemy-cli
Use the Alchemy CLI (`@alchemy/cli`) for live blockchain data, transaction lookups, NFT/token/portfolio queries, simulation, tracing/debugging, account abstraction (bundler + gas manager), webhook management, Solana RPC/DAS, and Alchemy app administration. Preferred runtime path for live agent work (querying, admin, local automation) when the CLI is installed locally — or when both CLI and MCP are available. If neither is installed, install the CLI with `npm i -g @alchemy/cli`. Use for live agent work in this session, not for building application code that ships to production. For application code, use the `alchemy-api` skill (with API key) or `agentic-gateway` skill (without).
123alchemy-mcp
Use the Alchemy MCP server (`https://mcp.alchemy.com/mcp`) for live blockchain data and admin work when MCP is wired into your AI client and the Alchemy CLI is NOT installed locally. Exposes 159 tools across 100+ chains for token prices, NFT metadata, transactions, simulation, tracing, account abstraction, Solana DAS, and app management. Use for live querying, analysis, admin work, or on-machine agent work — not for application code that ships to production. For application code, use the `alchemy-api` skill (with API key) or `agentic-gateway` skill (without). When the CLI is also installed locally, prefer `alchemy-cli` instead.
78alchemy-codex
Codex-facing entry point for building with Alchemy. Routes to `alchemy-api` for API key-based access or `agentic-gateway` for gateway-based access when the user has not chosen an auth path yet.
47allium
Query Allium APIs for wallet PnL (current + historical, by-wallet and by-token), holdings timeseries history, Hyperliquid HyperCore trading data (info, fills, orders, orderbook), and custom SQL analytics across 70+ chains. NOT for token prices, token metadata, current wallet balance snapshots, transaction transfer history, or NFT metadata — for those use `alchemy-cli` (live work), `alchemy-mcp`, `alchemy-api` (app code), or `agentic-gateway` (no API key). Requires Allium credentials at `~/.allium/credentials`.
