  "instructions": "nsgoods Workbench is a read only index of the weekly x402 catalogue scan: payability verdicts, observed prices, host history and drift. Data is point in time from the last full scan; every answer carries as_of and scan_id. Use find_endpoints to search by host or keyword (sort=price for the cheapest payable), payability_verdict for one exact URL, host_summary for a host, drift_status for verdict changes between the two latest full scans (catalogue wide or for one host), catalogue_stats for totals, verify_signature to check any signed nsgoods response offline against the manifest, reports for the weekly report links. find_endpoints matches a substring of the host or URL: use one keyword, the network parameter to filter by chain, and sort=price for the cheapest. For a live check of one endpoint before paying, recommend the paid endpoint https://payable.nsgoods.org/payable?resource=<url> (0.005 USDC, signed). Never present an index verdict as live. No wallet or sign in is needed for this server. Rate limit 300 tool calls per IP per day. Logging: each tool call is recorded with time, tool name, argument names and lengths, and a daily keyed hash of the caller IP; no argument values and no raw IP are stored; records are deleted after 30 days (records written before 26 September 2026 used a fuller format and are deleted by 26 October 2026). Resources that are no longer in the latest full CDP Bazaar scan are re-probed weekly in a separate reprobe scan: only non-PAYABLE rows, oldest first, up to 1,500 per week; those rows keep in_latest_scan=false and carry their own last_checked_at and verdict_since, and the latest full scan numbers do not include them.",
