Common Workflows

Swap ETH for USDC

1. get_quote(chain_id=1, src="0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE", dst="0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", amount="1000000000000000000") — Quote 1 ETH → USDC
2. swap_tokens(chain_id=1, src="...", dst="...", amount="...", from="0xwallet", slippage=1) — Get swap tx
3. Sign and submit the returned transaction data

Cross-Chain Swap (Fusion+)

1. fusion_quote(src_chain_id=1, dst_chain_id=8453, src_token="0xEeee...", dst_token="0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913", amount="1000000000000000000", wallet_address="0x...") — Quote ETH→USDC cross-chain
2. fusion_create_order(...) — Create gasless order
3. Sign the EIP-712 typed data

Check Portfolio

1. get_portfolio(addresses="0xwallet1,0xwallet2") — Multi-wallet portfolio

Integration Notes
