Aster API Docs

Official API documentation for Aster.

• 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.
