swap_quote | Best-price same-chain token swap quote via the KyberSwap aggregator (ethereum, base, arbitrum, optimism, polygon, bsc). Includes a disclosed 0.1% integrator fee. params: chain*, tokenIn*, tokenOut*, amount* |
swap_build_tx | Build an unsigned, non-custodial swap transaction (plus ERC-20 approval tx if needed) for the caller's wallet to sign. Same fee as swap_quote. params: chain*, tokenIn*, tokenOut*, amount*, sender*, recipient, slippageBps |
cow_quote | Gasless CoW Protocol market-order quote (ethereum, base, arbitrum, polygon, bsc; ERC-20 sell tokens). MEV-protected batch auction. Includes the same disclosed 0.1% fee as a CoW partner fee. params: chain*, tokenIn*, tokenOut*, amount*, sender, slippageBps |
cow_build_order | Build an unsigned CoW market order as EIP-712 typed data (eth_signTypedData_v4) plus the one-time vault-relayer approval tx if needed. No gas for the swap itself. params: chain*, tokenIn*, tokenOut*, amount*, sender*, recipient, slippageBps |
cow_post_order | Submit a signed CoW order (from cow_build_order) to the CoW Protocol order book; returns orderUid + explorer link. params: chain*, order*, signature*, sender*, quoteId |
cow_order_status | Status of a CoW order by uid. params: chain*, uid* |
zerox_quote | Same-chain swap quote via the 0x Swap API (ethereum, base, arbitrum, optimism, polygon, bsc) with the same disclosed 0.1% Quietwork integrator fee PLUS 0x's own ~0.15% platform fee (Standard plan; returned as zeroExFee), so total fees are higher than on KyberSwap. params: chain*, tokenIn*, tokenOut*, amount*, sender |
zerox_build_tx | Build an unsigned 0x Swap API (AllowanceHolder) transaction plus ERC-20 approval tx if needed; output goes to sender. Same fees as zerox_quote (0.1% ours + 0x's ~0.15% zeroExFee). params: chain*, tokenIn*, tokenOut*, amount*, sender*, slippageBps |
velora_quote | Same-chain swap quote via Velora (ParaSwap) Market (ethereum, base, arbitrum, optimism, polygon, bsc) with the same disclosed 0.1% Quietwork partner fee (Velora keeps 15% of it; no other Velora fee). Often a better price than KyberSwap on some pairs; compare with swap_quote. params: chain*, tokenIn*, tokenOut*, amount* |
