# Aster API Docs

Official API documentation for Aster.

## 🚀 Quick Start

- Use **V3 (Recommended)** for all new integrations
- Starting from **March 25, 2026**, V1 new API Key creation is no longer supported. Existing API Keys will continue to work.
- Starting from **September 1, 2026, 00:00 UTC**, all authenticated Spot V3 / Futures V3 endpoints (account, order, trade, and other USER_DATA / TRADE endpoints) are only accessible after the main wallet linked to the Aster account has completed a deposit. Agent Wallet and Builder endpoints, and public market data endpoints, are unaffected. Until the deposit is completed, affected requests return `{"code":-5050,"msg":"This function can only be used after deposit"}`. See [CHANGELOG](./CHANGELOG.md).
- Choose **EN** / **中文** based on your preference
