How this service works
X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.
Output
Returns a JSON object with a 'result' field containing bridge route details and a 'success' boolean indicating whether a route was found for the given source chain, destination chain, asset, and amount.
Example use cases
USDC transfer from Ethereum to Arbitrum
“I need to move 1000 USDC from Ethereum mainnet to Arbitrum — what's the best bridge route?”
ETH bridging to Optimism
“Can you look up the bridging route for 2 ETH going from Ethereum to Optimism?”
WBTC cross-chain to Base
“What route should I use to bridge 0.5 WBTC from Polygon to Base?”
Technical details
Endpoint
GEThttps://x402helper.xyz/89e509/bridge/route?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to programmatically discover cross-chain bridge routes between supported chains (Ethereum, Arbitrum, Base, Optimism, Polygon, BSC, Solana) and is willing to pay a small per-call USDC micropayment via the x402 protocol. Prefer this for automated DeFi workflows where routing logic must be resolved on demand.
Side effects
- Unsupported source or destination chain returns empty or failed route
- Invalid or unrecognized asset ticker may return no result
- Missing required src or dst query parameters causes request failure
- Payment of 0.065 USDC via x402 protocol required; missing payment returns 402 error
- Network timeout or upstream routing service unavailable
