Get Bridge Swap Price

This endpoint provides a real‑time swap quotation for transferring tokens between two blockchain networks using a designated bridge. It calculates the estimated amount of destination tokens that you would receive based on a given input token amount and token pair, factoring in the current liquidity and fees across the specified source and destination chains.

💡 Compute Unit Value: 40 (Fixed)

Query parameters

srcChainIdstring

The unique chain ID to specify the source chain. Find more here.

Example:1
bridgeId'600' | '300' | '400' | '500' | '100'

The unique ID to specify the bridge protocol for routing cross-chain queries or transactions. Find more here.

Example:600
dstChainIdstring required

The unique chain ID to specify the destination chain. Find more here.

Example:1
srcTokenSymbolstring

Symbol of the source token.

Example:usdt
dstTokenSymbolstring

Symbol of the destination token.

Example:ETH
srcTokenAddressstring

Contract address of the source (input) token on the source chain. For EVM chains, use a checksummed hex address (e.g., 0x...). Either srcTokenAddress or srcTokenSymbol must be provided.

Example:0xdAe2F6EdDdA6fb4fb60cc02633DE27e2b431B402
dstTokenAddressstring

Contract address of the destination (output) token on the destination chain. For EVM chains, use a checksummed hex address (e.g., 0x...). Either dstTokenAddress or dstTokenSymbol must be provided.

Example:0xdAe2F6EdDdA6fb4fb60cc02633DE27e2b431B402
amountInstring required

Amount of the input token to provide, specified in the token's smallest denomination (base units). Do not send human-readable decimal values. Examples: to swap 1 WETH (18 decimals), use "1000000000000000000"; to swap 1 USDC (6 decimals), use "1000000".

Example:1000000000000000000
