Free Access with Full Flexibility
One of the standout advantages of the OKX DEX API is that API access and usage are completely free for all partners. There are no hidden charges, subscription fees, or mandatory payments to begin integrating. This zero-cost entry lowers the barrier for developers and startups while enabling rapid prototyping and deployment.
Beyond free access, OKX provides tools for partners to generate revenue directly through their applications. Integration partners can configure referral commission rates and set custom fee recipient addresses, allowing them to earn from every token swap facilitated via the API.
To activate referral fees, partners simply include specific parameters in their swap quote requests. Once enabled:
- On most supported blockchains, partners can charge end users up to 3% per swap as a referral fee.
- For Solana-based transactions, this cap increases significantly to up to 10% per transaction, offering greater monetization potential on one of the fastest-growing blockchain ecosystems.
These commission structures give developers full control over their business models—whether offering low-fee services to attract volume or implementing premium features with higher margins.
Transparent Execution: No Hidden Gains
OKX DEX API prioritizes fairness and transparency in trade execution. When positive slippage occurs—meaning the actual execution price is better than the quoted price—the surplus value is handled with user benefit in mind.
In most cases, OKX retains none of the slippage surplus. Instead, the entire improvement in price is passed directly to the end user, enhancing trust and value delivery.
However, on the Solana network, integration partners have additional flexibility. They may choose to retain up to 10% of the slippage surplus as an optional earning mechanism. The remaining 90% (or more, if the partner chooses) is still returned to the user.
This model balances profitability for developers with ethical execution practices, ensuring users feel confident using platforms built on the OKX DEX API.
Non-Enterprise API: Scalable Entry-Level Access
For independent developers and early-stage projects, the Non-Enterprise API tier offers a stable and reliable foundation.
Key features include:
- Rate limits ranging from 1 to 5 requests per second (RPS)
- Default initial limit set at 1 RPS for new API keys
- Option to request an increase to 5 RPS via the developer dashboard
- No fees charged for usage under this tier
These constraints ensure system stability while still allowing meaningful development and testing. The absence of financial barriers makes it ideal for proof-of-concept builds, community tools, or lightweight DeFi interfaces.
As your application gains traction, upgrading to higher performance tiers becomes a natural next step—without any retroactive billing or penalties.

Enterprise API: Premium Features & Dedicated Support
For high-volume platforms, institutional integrations, or production-grade applications, the Enterprise API tier unlocks advanced capabilities tailored for scalability and performance.
Benefits include:
- Higher rate limits (beyond 5 RPS), customized based on use case
- Dedicated technical support with faster response times and direct engineering assistance
- Priority access to new features, beta programs, and exclusive product enhancements
- Eligibility for co-marketing opportunities and ecosystem grants
While the Non-Enterprise tier remains free, OKX plans to retain a portion of referral fees generated by Enterprise partners as a platform service fee. This revenue model supports continuous improvements in infrastructure, security upgrades, and long-term product development.
By sharing in the success of its partners, OKX aligns incentives across the ecosystem—driving innovation while maintaining sustainable growth.
