{"type":"firestarter.listing","listing":{"id":"lst_E4binNUp","product_name":"Acorn Copper Rain Chain","category":"Rain Chain","description":"Shaped after the acorn, this copper rain chain transforms a functional necessity into a sculptural garden detail. Each cup is generously proportioned and hand-tooled at the top, giving it a tactile quality that sets it apart from the ordinary. Unfinished and left to the elements, the copper will develop a rich natural patina over time,  growing more beautiful with every season. ","images":["https://cdn.shopify.com/s/files/1/0720/5824/1345/files/RainChainsLLC_AcornCopperRainChain_2688_7250.jpg?v=1780415543","https://cdn.shopify.com/s/files/1/0720/5824/1345/files/acorn.jpg?v=1780481898","https://cdn.shopify.com/s/files/1/0720/5824/1345/files/RainChainsLLC_AcornCopperRainChain_2688_diagram.jpg?v=1780415544"],"price":238,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:19.144Z"},"share_url":"https://firestarter.network/l/lst_E4binNUp","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
