Typed Alchemy

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

from typed_alchemy import Alchemy

async with Alchemy.new() as client:
  prices = await client.prices.by_symbol(symbols=['ETH', 'BTC'])
  transfers = await client.transfers(network='ethereum').get_asset_transfers(
    from_block='0x0',
    to_address='0x5c43B1eD97e52d009611D89b74fA829FE4ac56b1',
    category=['external'],
    max_count='0x2',
  )

Why Typed Alchemy?

• 🎯 Precise Types: Typed request and response models across Portfolio, Prices, NFT, Token, Transfers, Utility, and Simulation endpoints.
• ✅ Runtime Validation: Responses validated by default, not just typed on paper.
• ⚡ Async First: One shared async HTTP transport, ready for concurrent requests.
• 📚 Full Surface: Every supported network exposed uniformly, not just Ethereum.
