• ◐Sitemap present & freshrequired2/4

  Sitemap at https://www.perplexity.ai/sitemap.xml is valid XML with 7 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.

  Fetched /agents.md and checked for substantive agent guidance

  spec ↗report issue

Whether your pages carry machine-readable identity: structured data, llms.txt, clear copy an agent can quote.

• !Homepage states what you arerequirederror

  Homepage returned HTTP 403 — no content to evaluate

  An LLM read your homepage as an agent would and rated how confidently it could say what you do

  Docs found at https://docs.perplexity.ai/docs/getting-started/overview (via path probe, 1800 chars of readable text)

  report issue
• ◐MCP server discoveryrequired2.5/5

  MCP evidence found only as a mention in docs page (https://docs.perplexity.ai/docs/getting-started/overview): "mcp-server" — no well-known server card

  fix → Publish /.well-known/mcp/server-card.json describing your MCP endpoint so agents can autodiscover it. Evidence found: docs page (https://docs.perplexity.ai/docs/getting-started/overview).

  Probed /.well-known/mcp/server-card.json, mcp.json, and docs mentions for an MCP endpoint

  fix → Publish an official npm SDK (suggest @perplexity.ai/sdk) with your domain in package.json homepage so agents can verify it's official.

  Searched the npm registry for an official, domain-verified SDK package

  report issue

Whether your specs, docs, and tools are complete and descriptive enough for an agent to use them without guessing.

• —OpenAPI validity & qualityrecommendedna

  No OpenAPI spec found — nothing to lint

  Linted the spec: descriptions, operationIds, securitySchemes, servers

  report issue
• ◐Docs qualityrecommended1.8/3

  Docs at https://docs.perplexity.ai/docs/getting-started/overview scored clarity 4/5, completeness 3/5, runnable examples 1/5, agent-friendliness 4/5 (mean 3.0/5)

  fix → Docs scored 1/5 on runnable examples. The documentation provides an index for AI agents, but the actual content for each API is not provided in this truncated document, making it impossible to assess completeness or runnable examples.

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

  report issue
• ✗Quickstart / getting startedrecommended0/2

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

  Looked for a quickstart/getting-started guide containing code blocks

  report issue
• —MCP tool qualityrecommendedna

Response hygiene, TLS and redirect discipline, and security contact channels agents depend on at runtime.

• ◐TLS & redirect hygienerequired1/2

  http://perplexity.ai/ reaches https but ends in HTTP 403: http://perplexity.ai/ → https://perplexity.ai/ → https://www.perplexity.ai/

  fix → Redirect http→https in one hop and keep redirect chains ≤2; each hop costs agent latency and some clients give up.

  Checked http→https redirect behavior, chain length, and TLS health

  report issue
• !Response speed & weightrequirederror

  Homepage returned HTTP 403 — cannot assess response hygiene

  Measured homepage TTFB, payload size, and compression

  fix → Expose a crawlable /pricing page with literal plan prices and link it from your homepage nav.

  Followed nav/footer links and probed /pricing for a page with legible price signals
