How this service works
27 paid endpoints for trading bots
Output
Returns the recommended bridge protocol, optimal gas price in gwei or native units, estimated total bridging cost in USD, expected transaction latency, and possibly alternative route comparisons for the specified source and destination chains and token amount.
Example use cases
Arbitrage bot cross-chain routing
“My arbitrage bot needs to move 10 ETH from Ethereum to Optimism as cheaply as possible — what's the optimal gas price and which bridge should it use right now?”
DeFi yield farmer rebalancing
“I'm rebalancing my portfolio and need to bridge 50,000 USDC from Polygon to Base — give me the optimal gas estimate and recommended bridge with the lowest total cost.”
MEV bot gas optimization
“Before my trading bot executes a cross-chain bridge from Arbitrum to Avalanche for 2 WBTC, what's the optimal gas setting I should use to avoid overpaying?”
Technical details
Endpoint
POSThttps://x402-chain-intel.vercel.app/api/gas/optimal-bridgeWhen to prefer
Choose this endpoint when building a trading bot, arbitrage system, or DeFi automation tool that needs real-time optimal gas and bridge route data for cross-chain transfers. Prefer it over generic gas oracles when you specifically need bridge-aware cost optimization rather than simple on-chain gas estimates.
Side effects
- Unsupported source or destination chain pair returns an error or empty routes
- Invalid token address or unsupported token results in a 400-level error
- Bridge protocol unavailable or liquidity insufficient for the requested amount
- Payment of 0.17 USDC via x402 fails or is rejected, blocking the response
- Gas oracle data temporarily unavailable leading to stale or missing estimates
