  "notes": "2026-08-28 link-rot correction. The GitHub repo published as this entry's mcp_url until today, github.com/robbclarke/RB2B-APIs-MCP, 404d on 2026-08-27 and is gone. It is named here rather than left in the mcp_url field so the published page does not carry a link to a 404. The npm package's own homepage and repository fields still point at that dead repo. The npm package it shipped from is still live and installable. mcp_status stays official on that basis, but it is the weakest official claim in this file and needs a re-verification pass: RB2B's own docs host (docs.rb2b.com) now 302s to an /inactive path that returns 401, so there is no vendor documentation surface left to confirm against. Sources conflict on MCP status - a third-party directory (salestools.club) says \"Not available,\" but the npm package's maintainer email (robb@retention.com) matches RB2B's parent company Retention.com, a strong signal it's founder-maintained rather than a random fork; not confirmed via RB2B's own docs site. A separate OEM/API program runs $5,000/mo base + $0.10/resolution above 50,000/mo - enterprise-leaning for that tier specifically. Person-level ID is US-only.",
