Ethereum History — Agent Skill

Ethereum History exposes read-only, factual data about historical Ethereum mainnet contracts. Use this skill when the user asks about:

• A specific contract address (what is it, when was it deployed, who deployed it, bytecode, decompiled code, documented history)
• Early Ethereum contracts, deployment era (Frontier, Homestead, DAO fork, etc.), or undocumented/notable contracts
• Contract facts: deployer, deployment block/timestamp, short description, historical summary, links, metadata

All endpoints are GET only. No authentication required. Responses are JSON with snake_case keys.

Base URL
