{"type":"firestarter.listing","listing":{"id":"lst_yIPLIBzt","product_name":"Czech Black Pepper","category":"Vegetables","description":"An exceptional plant for edible landscaping, as the unripe pods that cover these plants are deep purply black in color, with shiny skin and a satisfyingly plump shape just bigger than a jalapeno. The pods ripen from this purple tone, landing at a sort of deep ruby red color when fully ripe. Black pods have a jalapeno-level heat; ruby ones can be quite a bit hotter.","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Czech-Black-Pepper-vendor-unknown-1630680458.jpg?v=1735579530"],"price":4.99,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:38.582Z"},"share_url":"https://firestarter.network/l/lst_yIPLIBzt","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
