{"type":"firestarter.listing","listing":{"id":"lst_SdqH5gqr","product_name":"Sugar Baby Watermelon","category":"Vegetables","description":"\"Sugar Baby\" is right -- this compact watermelon is sweetly mouthwatering. The high-producing plants make small, bowling-ball-like fruit bursting with sweet flavor. What's good about the size (and likeness to sporting equipment) is that this variety will not have to fight for space in your icebox or your garden, unlike other larger varieties. Picnic-perfect, small-space-taker, big flavor: Sugar Baby has it all. Oh baby! Mouthwateringly sweet.","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/products/IMG_7067.jpg?v=1735580322","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/IMG_7101.jpg?v=1735580322","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Sugar-Baby-Watermelon-vendor-unknown-1630676295.jpg?v=1735580322"],"price":4.99,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:39.551Z"},"share_url":"https://firestarter.network/l/lst_SdqH5gqr","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
