Score Breakdown
⚙ Agent Friendliness
🔒 Security
HMAC-SHA256 with 30s timestamp window; three-factor credential; granular permission scopes; IP whitelist available; dedicated simulated trading environment
⚡ Reliability
Best When
Building sophisticated trading agents that need access to one of the broadest crypto product suites (spot, derivatives, options, structured products, DeFi) on a single platform.
Avoid When
US-facing deployments or when regulatory clarity is required; also overkill for simple market data-only use cases.
Use Cases
- • Multi-asset algorithmic trading across spot, perpetuals, options, and structured products
- • Real-time market data streaming for tick-level price feeds
- • Unified portfolio management with cross-margin accounts
- • Earning yield via OKX's DeFi and earn products programmatically
- • Institutional-grade block trading and RFQ workflows
Not For
- • US retail users (OKX geo-blocks US IPs)
- • Purely on-chain/non-custodial trading workflows
- • Simple spot-only use cases where a simpler API suffices
Interface
Authentication
API key + secret + passphrase with HMAC-SHA256. Supports read-only, trade, and withdrawal permission scopes. IP whitelist supported. Simulated trading environment available.
Pricing
API access free; spot trading fees from 0.08% maker/0.10% taker (base tier); substantial fee discounts for high volume or OKB staking
Agent Metadata
Known Gotchas
- ⚠ Three-part credential (key + secret + passphrase) increases auth setup complexity
- ⚠ HMAC timestamp must be within 30 seconds of server time
- ⚠ clOrdId must be set for safe retries to prevent duplicate order submission
- ⚠ Account mode (simple, single-currency, multi-currency) affects endpoint behavior — agents must know account type
- ⚠ WebSocket connections require heartbeat (ping every 30s) to stay alive
- ⚠ Simulated trading environment available but separate API endpoint — good for agent testing
- ⚠ US IPs blocked; agent deployment geography matters
