  "instructions": "Market Category Booster maps free-text product descriptions onto the live\ncategory taxonomy of a marketplace (Amazon, eBay, Shopify, Google).\n\nRecommended order of calls:\n  1. `list_stores` (free) to learn the valid `store_id` values;\n  2. `payment_info` (free) if you have no API key and intend to pay per call;\n  3. `categorize_product` for the actual work.\n\nTwo things surprise most clients:\n  - `categorize_product` returns a LIST, one match per taxonomy level, from the\n    broadest to the most specific — not a single category id. Read the whole\n    list as a path.\n  - the descent has a token budget per request. When it runs out the last match\n    carries `truncated: true`: the path is valid but is not necessarily a leaf,\n    and the call is billed in full.\n\nAuthentication accepts either an `X-API-Key` HTTP header on the MCP session, or\nan x402 payment proof in the JSON-RPC `_meta` under `x402/payment`. With\nneither, `categorize_product` answers with the x402 payment requirements\ninstead of a result.\n",
