How this service works
Returns the best cross-chain bridge/swap route for a given source chain, destination chain, tokens and amount from LI.FI, including chosen bridge tool, estimated output, fees and gas. Powers autonomous cross-chain agents and agent-to-agent treasury movers that pick the cheapest, fastest bridge path for a transfer. Pay-per-call via x402 on Base. No charge on upstream failure.
Output
A JSON object containing the recommended bridge route for the specified transfer, including: the chosen bridge/swap protocol tool name, estimated output token amount at the destination, breakdown of bridge fees, gas cost estimates, and route metadata — all sourced from LI.FI's routing engine.
Example use cases
Treasury rebalancing across chains
“I need to move 10,000 USDC from our Ethereum treasury to Polygon for gas costs — can you find the cheapest bridge route via LI.FI and tell me the estimated output, fees, and which bridge it would use?”
Autonomous agent cross-chain payment routing
“Before my agent executes a cross-chain payment, get me a quote for bridging 2 ETH from Arbitrum to Optimism so I can compare the expected output and total fees.”
DeFi yield optimizer bridge planning
“I want to move funds to chase a yield opportunity — what's the best LI.FI route to bridge 5000 DAI from BNB Chain to Avalanche, and how much would I receive after fees and gas?”
Technical details
Endpoint
POSThttps://lifi-bridge-route-quote.hergertsynthora.com/serviceWhen to prefer
Choose this endpoint when you need a real-time, LI.FI-powered best-route quote for cross-chain token transfers without executing the transfer itself. Ideal for autonomous agents, treasury management bots, or DeFi applications that need to compare bridge options, estimate costs, and plan cross-chain movements before committing funds. Prefer this over generic DEX aggregators when the transfer involves moving tokens across different blockchain networks rather than swapping on a single chain.
Side effects
- Unsupported chain pair — no bridge route exists between the specified source and destination chains
- Unsupported token — the specified token is not available on one or both chains
- Amount too low — transfer amount is below the bridge minimum threshold
- LI.FI API unavailable — upstream service outage causes empty or error result
- Invalid payload format — malformed input schema returns error response
- No liquidity — insufficient liquidity on the selected bridge for the requested amount
