x402
BridgePilot Cross-Chain Bridge Route Quote is a paid API for AI agents from bridgepilot.onrender.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-31).
Fetches and compares cross-chain bridge route quotes from LI.FI and Across for EVM token transfers, ranks them by net USD value received, and returns the best route with alternatives.

How this service works
Cross-chain bridge route quotes: compares LI.FI and Across for EVM transfers (Ethereum, Base, Arbitrum, Optimism, Polygon), computes net received value in USD, filters unsafe routes and ranks the best one with alternatives. Quote only, non-custodial.
Output
Returns a ranked best bridge route plus up to N alternative routes, each including the bridge provider (LI.FI or Across), estimated net received value in USD, fees, estimated transfer time, and safety status. Unsafe routes are filtered out before ranking.
Example use cases
Best route for USDC to Base
“I want to move 500 USDC from Ethereum mainnet to Base — can you check both LI.FI and Across and tell me which bridge route leaves me with the most USDC after fees?”
Fast ETH bridge to Optimism
“I need to bridge 0.5 ETH from Arbitrum to Optimism as quickly as possible — use the fastest selection policy and show me the top route with up to 2 alternatives.”
Low-slippage USDC transfer to Polygon
“Quote me a bridge route for 1000 USDC from Ethereum to Polygon, but only show routes with max 50 basis points of slippage and a max total cost of $2.00 USD.”
Technical details
Endpoint
POSThttps://bridgepilot.onrender.com/v1/routes/quote?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a read-only, non-custodial comparison of cross-chain bridge routes across LI.FI and Across for EVM chains (Ethereum, Base, Arbitrum, Optimism, Polygon) before executing a transfer. It is ideal when you want to rank routes by net USD received or transfer speed, enforce safety filters, and see alternatives — without committing any funds. Use the sibling re-quote endpoint when you are ready to proceed to unsigned transactions.
Side effects
- No routes found if the token pair or chain combination is unsupported by either provider
- Constraints too strict (e.g. very low max_slippage_bps or max_total_cost_usd) may result in all routes being filtered out
- Invalid token symbol or chain key returns a validation error
- Amount too small may result in fees exceeding output, causing no viable routes
- Provider API downtime for LI.FI or Across may reduce available quotes
- Invalid EVM address format for sender or recipient triggers a parameter error
Input
Schema · Request body

|---|---|---|
| amount | string | Integer amount in the token smallest unit (USDC has 6 decimals: 100 USDC = "100000000"). |
| sender | string | Optional sender EVM address (improves quote accuracy). |
| providers | array | Optional subset of providers to query. |
| recipient | string | Optional recipient EVM address (defaults to sender). |
| constraints | object | |
| source_chain | — | Chain key (ethereum, base, arbitrum, optimism, polygon) or numeric chain id. |
| source_token | string | Token symbol from GET /v1/assets (e.g. USDC, ETH) or token contract address. |
| max_alternatives | integer | |
| selection_policy | string | |
| destination_chain | — | Chain key (ethereum, base, arbitrum, optimism, polygon) or numeric chain id. |
| destination_token | string | Token symbol or contract address on the destination chain. |
