AI + Alchemy API Integration Guide

Summary

A self-contained guide for AI agents integrating Alchemy APIs using an API key. This file alone should be enough to ship a basic integration. Use the reference files for depth, edge cases, and advanced workflows.

Before Making Any Request

Check if $ALCHEMY_API_KEY is set (e.g., echo $ALCHEMY_API_KEY).
If not set, do NOT proceed with API-key URLs. Use the agentic-gateway skill instead — it requires no API key.
If set, use the Base URLs + Auth table below.

Do This First

Choose the right product using the Endpoint Selector below.
Use the Base URLs + Auth table for the correct endpoint and headers.
Copy a Quickstart example and test against a testnet first.
