How this service works
BaseBuilder Defi API hub - 22 paid endpoints
Output
A list of available bridge routes for the requested token transfer, including supported bridge protocols, estimated output amounts, fees, and estimated transfer times for each route option.
Example use cases
Cheapest route for USDC bridging
“Find me all available bridge routes to move 1000 USDC from Arbitrum to Base, so I can pick the one with the lowest fees.”
Fastest ETH cross-chain transfer
“I need to transfer 0.5 ETH from Ethereum mainnet to Optimism as fast as possible — what bridge routes are available and which is the quickest?”
Token bridge protocol discovery
“What bridging protocols and routes support transferring WBTC from Polygon to Ethereum mainnet for a 0.1 WBTC amount?”
Technical details
Endpoint
POSThttps://bbx-defi.vercel.app/api/bridge/routes?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to discover available cross-chain bridge routes before executing a token transfer, especially when comparing multiple bridge protocols for cost or speed on Base-ecosystem chains. Prefer this over generic DEX aggregators when the use case is specifically cross-chain bridging rather than same-chain swaps.
Side effects
- Unsupported chain pair returns empty routes array or error
- Invalid token address results in 400 or no routes found
- Amount too low or too high for available bridge liquidity
- Chain ID not recognized returns validation error
- Network congestion may cause stale or unavailable route data
