How this service works
27 paid endpoints for trading bots
Output
Returns a breakdown of bridge fees for the specified cross-chain token transfer, including total fee amount, gas costs, protocol fees, and possibly the estimated time to completion. Data is intended for consumption by trading bots evaluating route profitability.
Example use cases
Cross-chain arbitrage cost check
“Before my bot buys ETH on Base and sells on Optimism, look up the bridge fees for moving 0.5 ETH from Base to Optimism so I can see if the arbitrage is still profitable after fees.”
Cheapest bridge route for DeFi yield
“I want to move 5000 USDC from Ethereum mainnet to Polygon to farm yield — what are the bridge fees right now so my bot can decide whether it's worth it?”
Multi-chain bot fee budgeting
“My trading bot needs to bridge WBTC from Avalanche to Ethereum — can you fetch the current bridge fees so I can budget the transfer cost before executing?”
Technical details
Endpoint
POSThttps://x402-chain-intel.vercel.app/api/bridge/fees?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your trading bot or DeFi automation needs real-time bridge fee data before executing a cross-chain transfer, especially when optimizing for cost across multiple bridge protocols. Prefer this over manually querying each bridge's UI when you need fee data programmatically at scale.
Side effects
- Unsupported chain pair returns an error or empty result
- Invalid token address causes a 400 bad request
- Bridge protocol temporarily unavailable returns 503 or null fees
- Stale fee data if on-chain conditions change rapidly
- Payment of 0.09 USDC required per call — missing payment header returns 402
