Frequently Asked Questions

Our API aggregates thousands of tokens across 50+ major blockchains including Ethereum, Binance Smart Chain, Solana, Polygon, Arbitrum, and many more. The list is continuously expanding as we integrate new decentralized and centralized liquidity sources.

Given the inherent volatility of cryptocurrency markets, standard quotes generated by our routing engine are valid for exactly 30 seconds. To secure the precise quoted rate, the transaction must be broadcasted within this tight window.

Standard tier users are allocated up to 10 requests per second (RPS) and 10,000 requests per month. If you represent an enterprise requiring higher throughput, please reach out to our team to define custom enterprise SLA limits.

We employ a transparent pricing model. The API does not inject hidden markups into the spreads. Instead, a tiny fractional routing volume fee is applied deterministically depending on your integration tier, guaranteeing you deliver the utmost value to your end-users.
