typed-etherscan

A fully typed, validated async client for the Etherscan API.

from typed_etherscan import Etherscan

async with Etherscan.new() as client:  # reads ETHERSCAN_API_KEY from the environment
  balance = await client.account.balance(address='0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae')
  print(balance)

Why Typed Etherscan?

🎯 Precise Types: Literal request parameters (module, action, closest, ...) so a typo is caught before the call leaves your machine.
✅ Runtime Validation: every response is validated against Etherscan's own status/message/result envelope by default.
⚡ Async First: async HTTP built on httpx, with a client-side rate limit for Etherscan's strict free-tier cap.
📚 Full Surface: all 88 documented Etherscan V2 endpoints — account, blocks, contracts, gas tracker, logs, raw proxy RPC, stats, tokens, transactions, and usage — across every chain the V2 API supports.
