Waiting for the agent’s first step…

Critical access needs attention

These checks describe whether an ordinary agent can enter, read, and operate the public site.

  • Agents can reach the site

    Crawler access and bot defenses.

    2 / 2 passed
  • Core content is available

    Useful content remains accessible without a fragile browser-only path.

    1 / 2 passed
  • Navigation fails safely

    Redirects and missing pages give agents a recoverable path.

    1 / 2 passed

Evaluated surfaces have material gaps

The public website is always evaluated. Optional surfaces appear when the scan finds positive evidence that they apply.

Fix these gaps first

Critical access gaps come first, followed by other applicable readiness gaps.

  1. 01

    Agent-friendly 404s

    Return a real HTTP 404 (or 410) status for nonexistent paths - never a 200 with your app shell, which makes agents believe every path exists. For full credit, give the 404 response a short markdown body pointing agents at your sitemap, llms.txt, or docs index. Verify with curl -s -o /dev/null -w "%{http_code}" https://yourdomain.com/some-path-that-does-not-exist - it must print 404.

    Critical access
  2. 02

    Content without JavaScript

    Server-side render your homepage so AI crawlers see meaningful content without JavaScript. Ensure an H1 and 500+ chars of text in raw HTML.

    Critical access
  3. 03

    OpenAPI spec published

    Publish an OpenAPI (Swagger) specification at /openapi.json or /api/openapi.yaml. This is how agents understand your API surface automatically.

    Other readiness checks
  4. 04

    Markdown content negotiation (acceptmarkdown.com)

    On the responses that serve text/markdown via Accept negotiation, add Accept to the Vary header (Vary: Accept, Accept-Encoding). Without it, CDNs can serve the cached HTML variant to an agent asking for markdown (or vice versa), depending on which variant landed in cache first.

    Other readiness checks
  5. 05

    Developer resource discoverability

    Make your developer resources (API docs, OpenAPI spec, auth docs, webhooks, MCP server) discoverable by name. Publish them at predictable URLs, list them in llms.txt, and include your product name in page titles and headings so search engines surface them for name-based queries.

  • Content without JavaScriptFailed

    Could not fetch homepage

    Recommendation

    Server-side render your homepage so AI crawlers see meaningful content without JavaScript. Ensure an H1 and 500+ chars of text in raw HTML.

  • Not blocked by bot detectionPassed

    Site accessible to 5 AI agent user-agents

    Recommendation

    Allowlist known AI agent User-Agents (ChatGPT-User, ClaudeBot, Google-Extended, DeepSeekBot) in your WAF or bot-detection rules.

  • Redirect hygienePassed

    No meta-refresh stubs, JavaScript-redirect stubs, or cross-domain hops across 5 checked pages

    Recommendation

    Replace meta-refresh and JavaScript-only redirects with real HTTP 301/302 redirects. Non-JS agents never execute location.href or wait for a meta refresh - they see only the stub page. Verify with curl -sI <url> - you should see a Location header, not a 200 with a near-empty body.

  • Content behind authPassed

    All 5 sampled pages are publicly readable (4 with substantive content)

    Recommendation

    Serve your content pages without a login wall. Agents cannot complete auth flows while browsing - a 401/403 or a login-form page is invisible content. Keep public documentation public; if some content must stay gated, publish an ungated summary so agents can still represent it.

  • OpenAPI spec publishedFailed

    No OpenAPI/Swagger specification found

    Recommendation

    Publish an OpenAPI (Swagger) specification at /openapi.json or /api/openapi.yaml. This is how agents understand your API surface automatically.

  • Markdown content negotiation (acceptmarkdown.com)Failed

    Two-representation negotiation works but Vary header missing Accept (got "rsc, next-router-state-tree, next-router-prefetch, next-router-segment-prefetch") - CDNs may cache wrong variant

    Recommendation

    On the responses that serve text/markdown via Accept negotiation, add Accept to the Vary header (Vary: Accept, Accept-Encoding). Without it, CDNs can serve the cached HTML variant to an agent asking for markdown (or vice versa), depending on which variant landed in cache first.

  • Agent crawler reachabilityPassed

    Reachable to all major AI crawlers - ChatGPT-User: reachable, ClaudeBot: reachable, Google-Extended: reachable, ora-agent: reachable, DeepSeekBot: reachable

    Recommendation

    Verify that major agent User-Agents can reach the homepage. If your WAF or bot rules block them, remove or narrow the blocking rule. Add an allow rule only when your security setup denies them by default.

  • OAuth 2.0 supportPassed

    OAuth authorization server metadata at https://v0.app (issuer=https://v0.app)

    Recommendation

    Implement OAuth 2.0 for API authentication. Publish your authorization server metadata at /.well-known/oauth-authorization-server.

  • Scoped permissionsPassed

    Scoped permissions documented at /docs

    Recommendation

    Support scoped API permissions (OAuth scopes or API key roles) so agents can request only the access they need.

  • JSON error responsesPassed

    API returns JSON error responses (404 at https://api.v0.app)

    Recommendation

    Return structured JSON error responses with error codes, messages, and resolution hints. Agents can't parse HTML error pages.

  • Agent-friendly 404sFailed

    Nonexistent paths return HTTP 200 with the app shell (soft-404). Agents probing for resources conclude every path exists. Return a real HTTP 404 status for unknown paths.

    Recommendation

    Return a real HTTP 404 (or 410) status for nonexistent paths - never a 200 with your app shell, which makes agents believe every path exists. For full credit, give the 404 response a short markdown body pointing agents at your sitemap, llms.txt, or docs index. Verify with curl -s -o /dev/null -w "%{http_code}" https://yourdomain.com/some-path-that-does-not-exist - it must print 404.

Recommended4 of 18 passed · 6.3 / 20 points
  • Developer resource discoverabilityFailed

    Agent searched for "v0" developer resources but found nothing relevant

    Recommendation

    Make your developer resources (API docs, OpenAPI spec, auth docs, webhooks, MCP server) discoverable by name. Publish them at predictable URLs, list them in llms.txt, and include your product name in page titles and headings so search engines surface them for name-based queries.

  • Brand name discoverabilityPartial (33%)

    v0.app appears once in brand-name search results for "v0" (position #5 out of 6)

    Recommendation

    Make sure a clean search for your brand name returns your own domain in the top results. If it does not, your brand may be too generic, conflict with a more established term, or not yet indexed. Strengthen brand-name search by claiming consistent NAP across listings, earning press mentions that link to the canonical domain, and avoiding redirect chains that mask the apex domain in search results.

  • Sitemap existsPassed

    Valid sitemap found at https://v0.app/sitemap.xml with multiple sitemaps entries

    Recommendation

    Add a valid XML sitemap at /sitemap.xml listing all indexable URLs. Include lastmod dates and keep it under 50MB.

  • Content efficiencyFailed

    Insufficient context: no homepage HTML available - agents have nothing to consume

    Recommendation

    Reduce markup overhead so readable text is at least 5% of your HTML. Strip unused inline scripts/styles, server-render content instead of shipping large JSON hydration blobs, and keep wrapper nesting shallow.

  • Content crawl depth signalsFailed

    Could not fetch homepage

    Recommendation

    Add and tags on paginated pages (blog archives, product listings, docs) so AI crawlers can traverse beyond the first page.

  • JSON-LD structured dataFailed

    Could not fetch homepage

    Recommendation

    Add JSON-LD structured data to your homepage using the identity type that matches your site - SoftwareApplication for products, Organization or LocalBusiness for companies, Person for personal sites, Article for blogs - with name, description, url, and type-appropriate fields (offers, sameAs, author) so AI can parse your identity programmatically.

  • Public API/docs linked from homepagePartial (33%)

    Documentation found at /api but not linked from homepage

    Recommendation

    Publish API documentation at a discoverable URL (/docs, /api, /developers). Include authentication, endpoints, and example requests.

  • Agent instruction / when-to-useFailed

    No agent instruction file with when-to-use guidance found

    Recommendation

    Tell agents when to reach for you: add a 'when to use this' section to your llms.txt (or a dedicated agent-instructions file) that names your best-fit use cases and how an agent should call you. Be specific about the jobs you are right for - generic marketing copy does not read as guidance.

  • Metadata completenessFailed

    Could not fetch homepage

    Recommendation

    Add all four signals to your homepage: , , , and . Agents use these for entity resolution and attribution.

  • Organization schema completenessFailed

    Could not fetch homepage

    Recommendation

    Add Organization JSON-LD that includes both contactPoint (with email/phone and contactType) and address (PostalAddress). This lets AI verify your business legitimacy and answer contact queries.

  • Trust anchor pagesFailed

    No trust anchor pages found with sufficient content (About, Contact, Privacy)

    Recommendation

    Publish real /about, /contact, and /privacy pages with at least 500 characters of content each. These are the pages AI agents check to verify your business is legitimate before recommending you.

  • Page token budgetPassed

    All 5 measured pages fit an agent context budget (largest ~12K tokens)

    Recommendation

    Keep each page's extracted text under ~100K characters (~25K tokens) so it fits an agent's context window without truncation. Split oversized reference pages into focused per-topic documents and link them from an index. Check a page with curl -s <url> | wc -c and remember agents read the extracted text, not the raw HTML.

  • Developer portalPassed

    Developer portal found at /docs

    Recommendation

    Create a developer portal at /developers with API keys, documentation, quickstart guides, and a sandbox environment.

  • Public API with reachable endpointsFailed

    No publicly reachable API surface detected (REST and GraphQL both absent or auth-gated)

    Recommendation

    Expose a public REST or GraphQL API. AI agents need programmatic access - not just a web UI - to integrate with your product.

  • Agent onboarding frictionFailed

    Insufficient content to evaluate onboarding friction

    Recommendation

    Offer a free tier or trial, self-serve API key generation, and a sandbox environment. Agents can't fill out 'contact sales' forms.

  • CLI tool availablePassed

    CLI package found on npm: v0-cli

    Recommendation

    Publish an official CLI tool on npm, PyPI, or Homebrew. A CLI lets agents and developers script interactions with your product without building API integrations from scratch.

  • API schema complexity analysisPartial (50%)

    REST: OpenAPI spec found but failed to parse for complexity analysis

    Recommendation

    Make your API spec self-describing: a unique operationId and a description on every operation, typed parameters, and response schemas. For GraphQL, a fully typed schema with a documented cost or rate limit reads best.

  • Function calling compatibilityPartial (50%)

    API spec found but couldn't validate function calling compatibility

    Recommendation

    Ensure API endpoints have unique operation IDs, typed schemas, and descriptions compatible with LLM function-calling formats.

Bonus signals7 positive · +1.5 points
  • pricing.md existsPartial (50%)

    pricing.md found at /pricing.md but thin (78 lines) - add plan tiers, prices, and feature breakdowns

    Recommendation

    Create a /pricing.md file with your pricing tiers, features, and limits in plain markdown. This lets AI agents compare costs and recommend plans without scraping HTML pricing pages.

  • Agent mode viewPassed

    Rich agent mode view at ?mode=agent with 6 agent signals and navigation links

    Recommendation

    Add a ?mode=agent query parameter to your homepage that returns a structured, machine-readable view with API endpoints, authentication info, and key capabilities instead of marketing HTML.

  • Markdown frontmatter metadataPassed

    Frontmatter with title + description and canonical on /

    Recommendation

    Open your served markdown docs with a --- frontmatter block carrying title plus at least one of description, canonical, or last-updated. Agents read frontmatter as document metadata without scraping. A Link: rel="canonical" response header also satisfies the canonical slot.

  • Markdown agent docsPassed

    Returns markdown when requested via Accept header

    Recommendation

    Pick one: (a) return Content-Type: text/markdown on GET when the request sends Accept: text/markdown, or (b) publish a static /llms.md, /auth.md, or /agents.md file at your root with real markdown content. Option (b) is usually a single static file. This is the cold-discovery path for agents that land at your homepage from web search without reading llms.txt first.

  • OAuth Protected Resource metadata (RFC 9728)Passed

    RFC 9728 metadata: resource=https://v0.app/api/mcp, authorization_servers (1)

    Recommendation

    Publish RFC 9728 protected-resource metadata at /.well-known/oauth-protected-resource. Include the resource field plus enough supporting metadata - your authorization servers, supported scopes, accepted bearer methods - that an agent can work out how to authenticate without first triggering a 401.

  • Agent auth discovery metadataPartial (33%)

    PRM + AS metadata both present but AS metadata has no agent_auth block

    Recommendation

    Publish RFC 9728 protected-resource metadata at /.well-known/oauth-protected-resource on your resource server (the host that actually serves the API, e.g. api.) with resource and authorization_servers. Publish RFC 8414 authorization-server metadata at /.well-known/oauth-authorization-server on the AS origin, and include the WorkOS auth.md agent_auth block with register_uri, identity_types_supported drawn from the spec enum (anonymous, identity_assertion - variants like verified_email or urn:ietf:params:oauth:token-type:id-jag belong inside identity_assertion.assertion_types_supported, not at the top level), and a sibling per-type block for each advertised type (anonymous.credential_types_supported; identity_assertion.assertion_types_supported + credential_types_supported) so agents can look up the request shape. Cross-link by listing the AS origin in PRM authorization_servers, and point agent_auth.skill back at your published /auth.md. Spec: https://workos.com/auth-md.

  • Sandbox / test environmentPassed

    Sandbox environment found at https://v0.app/docs/sandbox

    Recommendation

    Provide a sandbox or test mode so agents can exercise your API without touching production data, and document how to reach it - this lowers the risk of a destructive call against live data.
