# IndexEZ > Submit backlinks, monitor index status, and improve crawl discovery with automated indexing workflows for SEO professionals, agencies, and affiliate marketers. ## Content Signals (robots.txt) `https://indexez.com/robots.txt` declares: ``` Content-Signal: ai-train=yes, search=yes, ai-input=yes ``` (See https://contentsignals.org/) ## Authentication (user APIs only) Agents reading public markdown do **not** need OAuth. User APIs (`/api/projects`, etc.) use **Supabase Auth**. - https://indexez.com/.well-known/oauth-protected-resource — which authorization server to use (RFC 9728) - https://indexez.com/.well-known/openid-configuration — OIDC metadata (proxied from Supabase Auth) ## Agent discovery (Link headers) The homepage (`/`) returns RFC 8288 `Link` headers pointing to: - `/.well-known/api-catalog` — API catalog (`rel="api-catalog"`, RFC 9727) - `/llms.txt` — this file (`rel="describedby"`) - `/api/agent-markdown` — Markdown home document (`rel="service-doc"`) ## MCP This site does not expose an MCP server (no `/.well-known/mcp/server-card.json`). Use `/.well-known/api-catalog` and `Accept: text/markdown` on `/api/agent-markdown` for agent access. ## Agent access (Markdown for Agents) When this site is served through Cloudflare with **Markdown for Agents** enabled, request any public page with: ``` Accept: text/markdown ``` The app returns Markdown from `/api/agent-markdown` when that header is present. On localhost, `proxy.ts` rewrites pretty URLs (`/`, `/blog`, `/sites`, …) to the API automatically. **Production (indexez.com):** add nginx rewrite from `deploy/nginx/markdown-snippet.conf`, or call the API paths below directly. Direct API (works now on production): - https://indexez.com/api/agent-markdown - https://indexez.com/api/agent-markdown/sites - https://indexez.com/api/agent-markdown/sites/{hostname} - https://indexez.com/api/agent-markdown/about - https://indexez.com/api/agent-markdown/blog - https://indexez.com/api/agent-markdown/blog/{slug} ## Primary public pages - https://indexez.com/ — Product landing (features, pricing, FAQ) - https://indexez.com/sites — Tracked sites directory (Domain Rating, 30-day trends; newest 20 sites in the table) - https://indexez.com/sites/{hostname} — Per-site DR detail, trend chart, traffic insights when available, related sites ## Other public pages - https://indexez.com/about — Founder profile and project story (Markdown: Accept: text/markdown or /api/agent-markdown/about) - https://indexez.com/blog — SEO articles index (Markdown: Accept: text/markdown or /api/agent-markdown/blog) - https://indexez.com/blog/{slug} — Article detail (Markdown: Accept: text/markdown or /api/agent-markdown/blog/{slug}) - https://indexez.com/terms - https://indexez.com/privacy-policy ## Requirements (internal) Full checklist for homepage, sites list, and site detail: /docs/markdown-for-agents-requirements.md
