description: 'Kleio is a Paris-headquartered agentic commerce platform for complex, high-value enterprise
  sales, founded in 2024 by Adrien Mathieu, Philippe Wellens and Louis Poirier and backed by a EUR 3M
  seed round. The platform pairs a domain-specific Knowledge Engine — a continuously updated representation
  of a company''s catalog, pricing, business rules and ontologies — with a stack of orchestrated AI agents
  tuned for each stage of the sales funnel: discovery agents for intent qualification, product-guidance
  agents that reason over the catalog, quoting agents wired to configurators and pricing, and a Live Sales
  Copilot that augments human advisors in real time. Kleio deploys across web widgets, advisor desktops
  and third-party AI surfaces such as ChatGPT and Gemini via MCP/UCP integrations, with CRM and catalog
  write-back to Salesforce, HubSpot and custom systems. Named customers include Selectour, Havas Voyages,
  Showroomprive, Altarea Cogedim, Orpi and Emil Frey, across travel, real estate, automotive, wholesale,
  insurance, manufacturing and energy. Kleio publishes no public developer portal, API reference or
  OpenAPI: the platform API at api.kleio.ai is an OAuth-protected Google Cloud API Gateway reachable only
  to customers, and access begins with a sales conversation.'

  description: 'The Kleio platform API, served from api.kleio.ai behind a Google Cloud API Gateway and
    protected by OAuth 2.0 authorization-code + PKCE against an Auth0 tenant at auth.kleio.ai. Kleio
    publishes no public API reference or OpenAPI definition; the surface was established by probe — the
    gateway advertises RFC 8414 authorization-server metadata at
    https://api.kleio.ai/.well-known/oauth-authorization-server (HTTP 200) which names a dynamic client
    registration endpoint at https://api.kleio.ai/api/oauth/register (HTTP 405 to GET, confirming the
    route is defined). Every other probed path returns the gateway''s "The current request is not defined
    by this API" 404. Operations, schemas and scopes are not publicly documented.'

  detail: 'Kleio runs a real OAuth-protected platform API at api.kleio.ai — its Google Cloud API Gateway
    serves RFC 8414 authorization-server metadata naming an Auth0 issuer and a defined dynamic client
    registration route — but publishes no developer portal, API reference, OpenAPI or auth guide
    anywhere, and kleio.ai/pricing and kleio.ai/docs both 404, so the only route to the API is the
    "Request a Demo" form at kleio.ai/contact.'

x-pointer-omissions:
  note: 'Pointers deliberately NOT emitted, recorded so a later pass does not re-litigate them. Each was
    considered and rejected because the check asserts something Kleio does not publish.'
  omitted:
  - type: MCPServer
    reason: 'Kleio markets MCP/UCP integration in its own llms.txt and product page but publishes no
      endpoint; tools/list POSTs to every plausible path return the gateway 404. See mcp/kleio-mcp.yml
      (deployment.mode: none). The search-engine result app.getkleio.com/api/mcp belongs to a
      different company that shares the name.'
  - type: AgentCard
    reason: '/.well-known/agent-card.json and /.well-known/agent.json return 404 on every Kleio host.
      Search-only artifact; nothing written.'
  - type: StatusPage
    reason: 'status.kleio.ai has a real DNS record but returns a Cloudflare bot challenge (403) and
      could not be read. kleio.statuspage.io is a soft-404 redirecting to Atlassian marketing.'
  - type: Deprecation
    reason: No deprecation or versioning policy published.
  - type: SDKs
    reason: Zero first-party client libraries in any registry; the GitHub org has no public repos.
  - type: Compliance
    reason: 'The certifications in kleio.ai/security-policy (SOC 2, ISO 27001/27017/27018) are held by
      sub-processors — GCP, Redis Cloud, CockroachDB — not by Kleio.'
  - type: Pricing
    reason: No pricing page exists; kleio.ai/pricing 404s and the sitemap has no pricing URL.
  - type: DeveloperPortal
    reason: 'Kleio has no developer portal. kleio.ai/products and /agentic-discovery-engine are
      marketing pages; pointing a portal check at them would credit 4 pts for a surface that does not
      exist.'
  - type: Documentation
    reason: 'No API documentation of any kind. kleio.ai/docs and /developers both 404 and no docs
      subdomain resolves.'
  - type: APIReference
    reason: No API reference published.
  - type: GettingStarted
    reason: No quickstart or getting-started guide published.
  - type: SignUp
    reason: 'No self-service registration. kleio.ai/login 404s; kleio.ai/contact is a "Request a Demo"
      form, which is a sales gate rather than a sign-up.'
  - type: Postman
    reason: No public Postman collection or workspace found.
  - type: Roadmap
    reason: No public roadmap.
  - type: ChangeLog
    reason: 'No changelog or release notes. kleio.ai/changelog 404s and the sitemap lists none.'
  - type: AsyncAPI/Webhooks
    reason: No event, streaming or webhook surface is documented publicly.
  - type: AgentSkill
    reason: 'No OpenAPI exists to ground skills in, and skills must be grounded in real operationIds.'
  - type: Idempotency
    reason: No idempotency contract is documented or observable.
  - type: OpenAPI
    reason: 'No specification found after probing every spec path on www.kleio.ai, api.kleio.ai, the
      Cloud Run backend, and the non-resolving docs/developer/app subdomains.'
