Compare swap quotes across multiple DeFi protocols, including support for MEV-protected routing and execution model insights.

With the DeFi Swaps APIs, developers can:

Retrieve the best available swap price across protocols
Compare quotes from multiple DEXs and aggregators
Detect and filter MEV-protected swap routes
Build swap interfaces, trading dashboards, and DeFi wallets
Estimate fees, settlement time, and slippage-adjusted amounts
Power routing engines and portfolio applications

The APIs support both:

Exact-input swaps (kind=sell) — specify how much token to sell
Exact-output swaps (kind=buy) — specify how much token to receive

Supported ecosystems include major EVM networks such as:

Ethereum
BNB Smart Chain
Polygon
Arbitrum
Optimism
Base
Avalanche
And more

These APIs simplify building applications that surface real-time DeFi trading opportunities, routing intelligence, and MEV-aware execution across blockchain ecosystems. Read more about this feature in Swaps - DeFi APIs.
