Technical details
Endpoint
POSThttps://bb-defi.vercel.app/api/bridge/routesWhen to prefer
Use this endpoint when you need to discover available cross-chain bridge routes before executing a transfer, especially in the Base ecosystem. Prefer this over generic DEX aggregators when the user needs to move tokens between L1/L2 networks rather than swap on a single chain.
Side effects
- Unsupported chain pair returns empty routes or error
- Invalid token address returns 400 bad request
- No liquidity available on requested route
- Payment of ~$0.17 USDC required per call via x402 protocol or 402 error returned
- Amount too small or too large for available bridges
