Get offer creation actions

post
https://api.opensea.io/api/v2/offers/actions

Returns the blockchain actions needed to offer on an NFT, the offer-side counterpart of the listing actions endpoint. On EVM chains these are payment approvals followed by a Seaport order to sign, which the signature endpoints then accept. On Solana the actions instead carry an unsigned bid transaction to sign and submit onchain; there is no order to post back to OpenSea afterwards.
