  detail: 'Sync API markets itself as an "Enterprise API for the In-App advertising ecosystem" but ships no developer surface
    at all: the site is a five-page WordPress brochure with no docs, no reference, no signup and no SDKs, and the API host
    it advertised, api.sync-api.com, is authoritative NXDOMAIN on 8.8.8.8, 1.1.1.1 and 9.9.9.9 — so the placeholder baseURL
    was removed from this file. Every spec and /.well-known/ path returns the WordPress 404 template; the only machine-readable
    surface on the domain is the marketing site''s own WordPress REST API (/wp-json/, 268 CMS routes) and an auth-gated (401)
    WordPress MCP-adapter route, neither of which is the advertising product.'
