Creating a new order
Creating buy order with a lightning address would make the process way faster and easy going, to acomplish the buyer should send a Nostr event kind 4 (an encrypted message) to Mostro with the following content:
{
"order": {
"version": 1,
"pubkey": "0000147e939bef2b81c27af4c1b702c90c3843f7212a34934bff1e049b7f1427", // Buyer's real pubkey
"action": "new-order",
"content": {
"order": {
"kind": "buy",
"status": "pending",
"amount": 0,

"payment_method": "face to face",
"premium": 1,
"buyer_invoice": "mostro_p2p@ln.tips",
"created_at": 0
}
}
}
}
