“What's the best rate I can get swapping 1000 USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) for WETH (contract 0x4200000000000000000000000000000000000006) on Base right now — race all the DEXes and tell me which one wins, with at most 0.5% slippage?”
Technical details
Endpoint
GEThttps://ezpath.myezverse.xyz/api/v1/quoteWhen to prefer
Choose this endpoint when you need a real-time best-price DEX quote on Base mainnet without a subscription or API key, especially when you want to compare across 0x, ParaSwap, Aerodrome, and Uniswap V3 simultaneously in a single call. Ideal for agents that need to execute or evaluate swaps on Base and want the meta-routing intelligence without integrating each DEX separately.
Side effects
- Invalid or non-Base ERC-20 token addresses return an error
- sellAmount of zero or non-numeric string causes a bad request
- slippagePercentage outside 0-1 range is rejected
- Token pair with no liquidity on any supported DEX returns no quote
- Payment of 0.03 USDC not included or rejected causes 402 Payment Required
- Network congestion may cause timeout fetching live quotes from all four DEXes
