{"type":"firestarter.listing","listing":{"id":"lst_cjqWRTZL","product_name":"Scarlet Nantes Carrot","category":"Vegetables","description":"This heirloom carrot originally from France has been improved in the U.S. over the last 50 years. It is now one of the most uniform and easy to grow open-pollinated carrot varieties. The rounded ends of the six-inch roots have even been known to grow well in heavier soils. Crisp texture, deep orange color, and good storage make this a home garden favorite.","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Scarlet-Nantes-Carrot-vendor-unknown-1630676251.jpg?v=1735580330","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Scarlet-Nantes-Carrot-vendor-unknown-1630676254.jpg?v=1735580330","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Scarlet-Nantes-Carrot-vendor-unknown-1630676257.jpg?v=1735580330"],"price":4.39,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:39.580Z"},"share_url":"https://firestarter.network/l/lst_cjqWRTZL","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
