typed-aster 0.5.0

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

• Documentation: https://tribulnation.com/typed/aster
• Source Code: https://github.com/tribulnation/typed/tree/main/packages/aster

from typed_aster import Aster

async with Aster.new(public=True) as client:
  book = await client.futures.market.depth('BTCUSDT', limit=5)
  print(book['bids'][0])

One Aster client covers five surfaces:

• client.futures: perpetual futures
• client.spot: spot trading
• client.prediction: prediction markets
• client.chain: Aster Chain (staking, transfers, withdrawals, and on-chain reads by address)
• client.bapi: the web app's public API (every asset that can be deposited or withdrawn)

Public market data needs no credentials. Everything signed uses Aster's Pro API wallets. See Authenticated Setup.

Why Typed Aster?

• 🎯 Precise Types: Typed order unions and datetime timestamps across futures, spot, prediction and Aster Chain, not dict/Any. Prices and quantities Aster sends as strings are Decimal; the few amounts it sends as JSON numbers (Aster Chain balances such as walletBalance, withdrawal fee estimates, fee caps) are float.
• ✅ Runtime Validation: Every REST, JSON-RPC and WebSocket response is validated by default, not just typed on paper.
• ⚡ Async First: Async HTTP plus WebSocket market and user-data streams, built for concurrent workflows.
• 📚 Full Surface: Every documented Pro API endpoint, including strategy orders, sub-accounts, builders, prediction outcomes and staking.
