How this service works
HALOWERK defiwerk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.
Output
Returns a bridge quote object containing the estimated output token amount on the destination chain, applicable bridge fees, the bridge protocol or route selected, exchange rate, and any slippage estimates. Used to evaluate cost and feasibility before executing an actual cross-chain transfer.
Example use cases
Cheapest route for USDC bridging
“I want to move 1000 USDC from Base to Arbitrum — can you get me a bridge quote showing estimated output and fees? The USDC contract on Base is 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913.”
Cross-chain ETH transfer estimate
“What's the best quote for bridging 0.5 WETH from Ethereum to Optimism? WETH address on Ethereum is 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2, amount is 500000000000000000.”
Pre-trade bridge cost check
“Before I execute a bridge, can you get me a quote for moving 2000 DAI from Ethereum to Base? The DAI contract is 0x6B175474E89094C44Da98b954EedeAC495271d0F and I want to know the output amount and any fees involved.”
Technical details
Endpoint
POSThttps://defi.netzhandwerker.de/bridge/quoteWhen to prefer
Use this endpoint when you need a real-time, paid cross-chain bridge quote between EVM-compatible chains and want per-call micropayment pricing via x402/USDC rather than API-key subscriptions. Prefer it for agents operating autonomously on Base Mainnet that need bridge cost estimation before executing a transfer.
Side effects
- Unsupported chain pair returns an error indicating no route available
- Invalid token contract address (not 0x + 40 hex chars) returns a validation error
- Amount of zero or negative value may return an error or empty quote
- Token not supported on destination chain returns no-route error
- Network congestion or bridge provider downtime may cause timeout or empty response
- Missing required fields (token, amount, to_chain, from_chain) returns a 400-level error
