Technical details
Endpoint
GEThttps://beggar-bot-demand.beggarbot.workers.dev/v1/cowquote?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a CoW Protocol-specific swap quote on Base mainnet, particularly when you want CoW's batch auction routing and MEV protection pricing rather than a generic DEX aggregator quote. Prefer this over Uniswap or other DEX quote endpoints when optimizing for CoW Protocol execution.
Side effects
- Unsupported token pair returns an error or empty quote
- Invalid token contract addresses cause a failed lookup
- Network congestion may cause stale or unavailable quotes
- Payment failure via x402 (insufficient USDC balance) blocks the call
- Requesting an unsupported network other than base or base-sepolia returns an error
