How this service works
Get bridge options, fees, and timing estimates for cross-chain transfers
Output
Returns a list of bridge options (e.g. Across, Stargate, Arbitrum Bridge) with estimated fee percentages, fee in USD, transfer time estimates, trust model descriptions, minimum amounts, and a top recommendation. Also includes a disclaimer that values are estimates and the endpoint cannot execute transactions.
Example use cases
Example prompt
“I want to bridge $500 USDC from Ethereum to Arbitrum — can you show me all the bridge options with their fees, estimated transfer times, and which one is recommended?”
Technical details
Endpoint
POSThttps://defi-shield-hazel.vercel.app/api/chain/bridge-quoteWhen to prefer
Use this endpoint when an agent needs to compare multiple bridge protocols for a cross-chain transfer, evaluate trade-offs between speed, cost, and trust model, or recommend the best bridge for a given amount and chain pair. Prefer this over executing a bridge directly since this is informational/advisory only.
Side effects
- Unsupported chain pair returns error or empty options list
- Amount below bridge minimums may filter out some options
- Fees and timing are estimates and may not reflect real-time conditions
- Truncated or incomplete response if bridge data source is unavailable
- Invalid chain name input may cause a 400 or empty result
