Output
Returns the current swap rate for the specified cross-chain bridge route, including the exchange rate, estimated output token amount after fees, bridge protocol fee, and estimated slippage for the given input amount and token pair.
Example use cases
Arbitrage bot cross-chain pricing
“Check the current bridge swap rate for moving 2000 USDC from Ethereum to Arbitrum — I want to know the exact output amount and any fees before my bot decides whether to execute the arbitrage.”
Portfolio rebalancing across chains
“What rate will I get if I bridge 1 ETH from Ethereum mainnet to Optimism right now? I'm rebalancing my portfolio and need the live swap rate and estimated WETH output.”
DeFi yield strategy routing
“Get me the bridge swap rate for converting 5000 USDT from Polygon to Avalanche — I'm comparing bridge rates to find the cheapest path for my yield farming strategy.”
Technical details
Endpoint
POSThttps://x402-chain-intel.vercel.app/api/bridge/swap-rate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your trading bot or DeFi agent needs a real-time cross-chain bridge swap rate quote before executing a bridge transaction. It is best suited for latency-sensitive arbitrage bots, cross-chain rebalancing agents, and yield routing strategies that need accurate, up-to-date pricing data across multiple blockchain networks. Prefer this over generic DEX rate APIs when the operation specifically involves bridging assets between different chains rather than same-chain swaps.
Side effects
- Unsupported chain pair returns an error indicating the bridge route is not available
- Invalid or unrecognized token address returns a validation error
- Amount below minimum bridge threshold returns an error with minimum required
- Network congestion or RPC downtime may cause timeout or stale rate response
- Incorrect token decimals in input may produce inaccurate rate calculations
