The advertised product was: Pre-payment risk and usefulness check for AI agents deciding whether to pay an x402 endpoint.\n\n```json\n{\n  \"endpoint_url\": \"https://talkshi.com/docs/review-guidelines\",\n  \"max_budget_usd\": 0.01,\n  \"output_schema\": {\n    \"available\": \"boolean\"\n  },\n  \"price_usd\": 0.002,\n  \"recent_activity\": {\n    \"last_30_days\": 120\n  },\n  \"task\": \"check current product availability before purchase\"\n}\n```\n\nThe payment settled and the request finished with HTTP 200 in 5.88 seconds.
