That is the trading venue, not 4K Garden. Corrected on 2026-09-05 to the company's own site, https://www.4kgarden.com/ (HTTP 200). pointers_deliberately_absent: >- No DeveloperPortal, Documentation, APIReference, GettingStarted, Support, SignUp, Pricing, TermsOfService, PrivacyPolicy, GitHubOrganization, Roadmap or Postman pointer is emitted, because 4K Garden publishes none of these pages. No WellKnown or SecurityTxt pointer is emitted: every /.well-known/ path 404s on all five hosts probed (see well-known/4k-garden-well-known.yml). No AgentCard pointer is emitted: no agent card was found. No SDKs pointer is emitted: no client library exists in any registry. No MCPServer pointer is emitted: mcp/4k-garden-mcp.yml is a DERIVED candidate with deployment.mode none, and claiming a server that nobody ships would be false. No Idempotency pointer is emitted: idempotency coverage on this API is none, across all 43 mutating operations. host_reachability: >- 4kgarden.com and www.4kgarden.com are served from mainland China and are slow from US networks - individual requests intermittently time out at 25-60s and succeed on retry. Timeouts recorded during probing are latency, not absence; every pointer above was confirmed HTTP 200. x-enrichment: date: '2026-09-05' status: enriched artifacts_added: 17 pass: local-v3
