Whether agents can crawl you, find you in the registries and searches they check, and trust what they find.

• ✓Sitemap present & freshrequired4/4

  Sitemap at https://www.ebay.com/lst/AUCTION-0-index.xml: 54 entries, freshest <lastmod> 2026-08-16 (2 days ago)

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

  spec ↗report issue
• ✗Brand search discoverabilityrequired0/4

  Neither search ("eBay", "eBay e commerce") cited ebay.com. Cited instead: https://www.addtosheets.com/save/ebay-to-google-sheets/, https://scrape.do/blog/ebay-scraping/, https://uscraper.io/templates/ebay_export, https://clura.ai/blog/ebay-scraper, https://uscraper.io/templates/ebay-scraper

  fix → Your domain doesn't surface when agents search "eBay". Strengthen brand pages, structured data, and third-party citations (docs portals, GitHub, directories).

  Ran clean brand-name web searches and checked whether your domain is cited in the results

• —MCP registry listingsrecommendedna

  No MCP server detected for this product

  Queried the official MCP registry, Smithery, Glama, and PulseMCP for servers matching your domain

Whether your robots policy, bot protection, and agent guidance actively admit AI agents instead of blocking them.

• ✓robots.txt present & parseablerequired2/2

  /robots.txt parses: 8 User-agent group(s), 7 Sitemap line(s)

  Fetched /robots.txt and validated it parses as a robots policy

  spec ↗report issue
• ✗AI crawler policyrequired0/5

  robots.txt blocks 7 of 12 AI crawler user-agents from /: GPTBot, ClaudeBot, anthropic-ai, PerplexityBot, CCBot, meta-externalagent, Bytespider

  fix → robots.txt blocks GPTBot, ClaudeBot, anthropic-ai, PerplexityBot, CCBot, meta-externalagent, Bytespider. Add explicit `User-agent: <bot>` / `Allow: /` groups for the AI agents you welcome; a blanket Disallow makes you invisible to them.

  Evaluated robots.txt groups for the major AI agent user-agents (GPTBot, ClaudeBot, PerplexityBot, …)

  report issue
• ✗Content Signals directivesemerging0/2

  No Content-Signal lines in robots.txt

  fix → Declare Content Signals in robots.txt (e.g. `Content-Signal: search=yes, ai-train=no`) to express AI usage preferences machine-readably.

  Looked for Content-Signal lines in robots.txt

  spec ↗report issue
• !Agent user-agent paritybetarequirederror

  Compared responses served to browser and AI-agent user-agents (informational while in beta)

  report issue
• ✗agents.mdrecommended0/3

  No agents.md: https://ebay.com/agents.md → HTTP 404, https://ebay.com/AGENTS.md → HTTP 404

  fix → Add /agents.md: what agents may do on your site, key URLs, auth, rate limits, and who to contact.

  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

  GET /llms.txt returned HTTP 404

  fix → Add /llms.txt: an H1 with your name, a one-line blockquote summary, and H2 sections of curated links to docs, pricing, and API.

  Fetched /llms.txt and validated it against the llmstxt.org shape (H1, summary, curated links)

  spec ↗report issue
• ✗llms-full.txtbonusrecommended0/2

  fix → Add /llms-full.txt with expanded inline docs content so agents can load everything in one fetch.

  Fetched /llms-full.txt and checked for substantial inline markdown content

  spec ↗report issue

  GET / with `Accept: text/markdown` returned HTTP 403 text/html; no .md twins found (1 probed)

  Requested key pages with Accept: text/markdown and probed .md twin URLs

  report issue

Whether the artifacts an agent needs to build on you — docs, API specs, SDKs, MCP servers — exist and are findable.

• ◐Developer resource discoverabilityrecommended1/3

  Search "eBay API documentation" cited no ebay.com URL — only third-party content describes your API: https://www.postman.com/api-evangelist/ebay/request/gxd9072/get-item-summary-search, https://www.searchapi.io/docs/ebay-search-api, https://stackoverflow.com/questions/34615760/search-ebay-using-the-api-from-r, https://serpapi.com/ebay-search-api

  fix → Create a crawlable /docs or developers.ebay.com hub and link it from your homepage footer so search-grounded agents find your official API docs.

  Searched for your brand with developer-keyword suffixes and checked which official resources are cited

  report issue
• ✗OpenAPI spec discoverablerequired0/5

  No OpenAPI spec found: checked docs-page links and /openapi.json, /openapi.yaml, /swagger.json, /api/openapi.json, /docs/openapi.json, and api-subdomain locations

  fix → Publish your OpenAPI spec at /openapi.json and link it from docs — it's the single highest-leverage artifact for agent integration.

  Probed standard OpenAPI locations and docs links for a fetchable, parseable spec

  spec ↗report issue

  No MCP evidence found: probed /.well-known/mcp/server-card.json, /.well-known/mcp.json, /mcp.json and scanned llms.txt, agents.md, and docs for endpoints or install commands

  fix → Publish /.well-known/mcp/server-card.json describing your MCP endpoint so agents can autodiscover it. Evidence found: none.

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

  report issue
• —Docs qualityrecommendedna

  No documentation found to evaluate

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

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

• ◐TLS & redirect hygienerequired1/2

  http://ebay.com/ reaches https but ends in HTTP 403: http://ebay.com/ → https://ebay.com/ → https://www.ebay.com/

  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

Whether agents can discover your auth model machine-readably (OAuth metadata) and follow documented steps to credentials.

• ✗OAuth authorization server metadatarecommended0/3

  Neither /.well-known/oauth-authorization-server nor /.well-known/openid-configuration resolved (HTTP 404 / HTTP error)

  fix → Serve RFC 8414 metadata at /.well-known/oauth-authorization-server with PKCE (S256) and a registration_endpoint so agents can self-onboard.

  Fetched /.well-known/oauth-authorization-server (and openid-configuration fallback)

  spec ↗report issue
• ✗OAuth protected resource metadatarecommended0/2

  No RFC 9728 metadata: https://ebay.com/.well-known/oauth-protected-resource → HTTP 404

  fix → Serve RFC 9728 metadata at /.well-known/oauth-protected-resource naming your authorization servers so agents can discover how to authenticate.

  Fetched /.well-known/oauth-protected-resource

  spec ↗report issue
• ✗Auth documentationrecommended0/2

  No /auth.md and no docs page to search for authentication documentation

  fix → Document auth end-to-end (key creation → header format → example call), or ship /auth.md.

  Looked for /auth.md or an authentication docs page with code examples

  report issue

Whether pricing is discoverable and machine-readable, and whether you support agent payment protocols.

• ✗Pricing discoverablerequired0/5

  No pricing page found: no homepage link matching pricing/plans/billing, and probes of /pricing and /plans returned no HTML page.

  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

  report issue
• —Machine-readable pricingrecommendedna

  No pricing page found to evaluate

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

  spec ↗report issue
• ✗x402 payment supportbonusrecommended0/2

  /.well-known/x402 returned HTTP 404. No x402 support detected (bonus check — absence costs nothing).
