• ◐Sitemap present & freshrequired2/4

  Sitemap at https://auth0.com/sitemap.xml is valid XML with 954 entries but contains no <lastmod> dates

  fix → Publish /sitemap.xml, reference it from robots.txt, and include <lastmod> dates so agents can tell what's current. Freshest lastmod seen: none.

  Resolved the sitemap from robots.txt or /sitemap.xml, validated XML, and checked lastmod freshness

• ✗Docs qualityrecommended0/3

  Docs at https://auth0.com/ai/docs/intro/overview scored clarity 3/5, completeness 2/5, runnable examples 1/5, agent-friendliness 1/5 (mean 1.8/5)

  fix → Docs scored 1/5 on runnable examples. The documentation provides a high-level overview and links to quickstarts but lacks concrete, actionable steps or API references for an AI agent to directly implement authentication and authorization.

  An LLM rated your docs for clarity, completeness, runnable examples, and agent-friendliness

  report issue
• ✗Quickstart / getting startedrecommended0/2

  Quickstart page https://auth0.com/ai/docs/get-started/overview exists but contains no code block (<pre> or fenced code)

• ◐Machine-readable pricingrecommended2.5/5

  Pricing at https://auth0.com/pricing is extractable only via inference and stays ambiguous — only contact-sales/unpriced plans came back (confidence 0.50): Startups (contact sales); Nonprofits (contact sales). No Offer JSON-LD on the page.

  fix → Add Offer JSON-LD per plan (name, price, priceCurrency, billing period) to https://auth0.com/pricing so pricing parses without inference.

  Looked for Offer JSON-LD, then had an LLM attempt structured extraction of your plans
