Check an endpoint URL you already hold before paying it. Returns match 'active' with the full record (as get_service_details), 'delisted' (listed here, later removed: treat as a warning), or 'unknown' (never checked here; absence is not a verdict either way). Report what the record shows, with its dates; do not call an endpoint safe or unsafe yourself. The paid verdict applies our published rule for you and, on caution or avoid, names verified alternatives: GET https://api.nohumans.directory/v1/listings/{id}/verdict ($0.005 USDC on Base via x402). Use find_paid_service instead when you have a need but no URL. Free, read-only.
