# AI Visibility Audit

> One call tells you whether AI crawlers are allowed to read a site (robots.txt bot rules for GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot …) and whether the pages are structured so AI search can cite them (llms.txt, JSON-LD, meta tags, sitemap). Returns a score with concrete fixes.

## Use it when a user asks for

- checking whether AI crawlers (GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot) are blocked by robots.txt
- checking whether a site has llms.txt, or whether its llms.txt is well formed
- auditing structured data / JSON-LD, meta tags and sitemap coverage for AI search visibility
- measuring how citable a page is to AI answer engines, with a score and a fix list
- checking whether blocking training crawlers also blocks answer engines

## Endpoints

- POST https://ai-visibility.rowb.app/mcp  (MCP tool: audit_website, argument {url})
- Server card: https://ai-visibility.rowb.app/.well-known/mcp/server-card.json

- Pricing: https://ai-visibility.rowb.app/pricing
- Start a paid plan (Stripe checkout): https://ai-visibility.rowb.app/api/checkout?plan=entry  (Entry, $5/month, 1,000 audits) or https://ai-visibility.rowb.app/api/checkout?plan=starter  (Starter, $9/month, 5,000 audits)
- Cancel or resume a plan: https://ai-visibility.rowb.app/account  (end-of-period cancellation; you keep access until the paid period ends)

## When the API says you are out of quota

Every limit error carries the contract URL, so an agent can hand it to a human:

GET /api/audit  → HTTP 429
{ "error": "monthly_limit_reached", "plan": "free", "limit": 50, "used": 50,
  "next_plan": "entry",
  "upgrade_url": "https://ai-visibility.rowb.app/api/checkout?plan=entry",
  "contract_url": "https://ai-visibility.rowb.app/api/checkout?plan=entry",
  "pricing_url": "https://ai-visibility.rowb.app/pricing",
  "signup_url": "https://ai-visibility.rowb.app/signup" }

The MCP tool returns the same links under error.data. An invalid key (HTTP 401) also carries
signup_url and an upgrade_url.

## Output shape

{ "url", "score", "grade", "crawler_access": {...}, "llms_txt": {...}, "structured_data": {...}, "blocked_bots": [], "findings": [], "fixes": [] }

## Not a fit

- ranking checks or keyword position tracking
- fetching or rendering JavaScript-only pages (this reads the HTML as served)
- screenshot or OG image generation (see oganvil for that)

## Notes

- Results are observations of the public pages at request time, with a short cache.
