{"type":"firestarter.listing","listing":{"id":"lst_PaAh0xW2","product_name":"Bio Char","category":"Soil","description":"Biochar is a natural soil enhancer that works below the surface to build healthier, more resilient soil. As it integrates, it improves water retention, reduces nutrient loss, and creates a porous habitat where beneficial microorganisms can thrive. At the same time, biochar locks carbon into the soil for hundreds of years to come, supporting both your garden and the broader environment.\nMade responsibly in New Hampshire.","images":["https://cdn.shopify.com/s/files/1/0720/5824/1345/files/Bio_Char_02.jpg?v=1777642338","https://cdn.shopify.com/s/files/1/0720/5824/1345/files/Bio_Char_05.jpg?v=1777642338","https://cdn.shopify.com/s/files/1/0720/5824/1345/files/Bio_Char_06.jpg?v=1777642338","https://cdn.shopify.com/s/files/1/0720/5824/1345/files/Bio_Char_04.jpg?v=1777642338"],"price":28,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:19.565Z"},"share_url":"https://firestarter.network/l/lst_PaAh0xW2","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
