payerIf you sponsor transactions for your users with
payer on /order, you can now get JupiterZ quotes, which often means better prices on major pairs. Market makers cover signature and priority fees, and payer only pays rent when a new output token account is needed.Note:
payer is a required signer on JupiterZ routes, except for native SOL output. Only sign with payer when the transaction requires it, otherwise native SOL output swaps will fail.Docs: https://developers.jup.ag/docs/swap/advanced/gasless#integrator-payer
