`Optional` `Readonly`vendor

vendor?: string

RFQ vendor name. Required for equity / RWA tokens (Ondo, BStock); pass the vendorName from the /quote response (e.g. InchFusion, CowSwap, PcsXRfq). When provided, the backend returns approve calldata targeting the vendor-specific spender contract (e.g. 1inch Router, PcsX Permit2, CowSwap VaultRelayer) instead of the default DEX router.

For regular (non-RWA) tokens, this parameter is optional. If omitted, the backend uses the standard DEX router. If a valid RFQ vendor is passed, the backend resolves that vendor's spender — used when buying Ondo/BStock with a stablecoin, where the from-token (e.g. USDT) itself is not an RFQ token but must be approved to the RFQ vendor's router.
