api: kelvin API
note: >-
  kelvin's primary distribution channel is not an SDK — it is embeddable, hosted UI.
  The company ships no client library on any registry, and instead gives customers a
  hosted simulator they place on their own site plus an iframe component the API
  documentation itself tells integrators to embed. No component here is distributed as
  an npm/CDN package: each is a hosted surface reached by URL or iframe, and the
  embed snippets are issued per customer rather than published, so no verbatim code is
  recorded below.
families:
- name: Simulateur kelvin°
  description: >-
    The address-based renovation simulator. A prospect enters an address, and within a
    minute the component returns renovation scenarios, available public aid and a
    budget estimate, converting the visitor into a qualified contact for the customer's
    sales team.

  distribution: hosted
  variants:
  - name: Hosted link
    mode: standalone-url
    description: >-
      A personalised web address for the customer's simulator, usable directly in a
      site CTA, a social post or an ad campaign. No code required.
  - name: Address widget + redirect
    mode: embedded-widget
    description: >-
      An address-entry widget placed on the customer's own page that hands off to the
      hosted simulator.
  - name: iframe embed
    mode: iframe
    description: >-
      The whole simulator experience runs inside a frame on the customer's domain, or
      inside their own software, so the visitor never leaves the site. kelvin's
      resources page states the full iframe integration documentation is supplied on
      request rather than published.
  - name: API-only
    mode: api
    description: >-
      For customers building their own interface, the same AI engine is reachable
      through the kelvin API — the simulator's UI is skipped and only the building-data
      enrichment and scenario generation are consumed.
    spec: openapi/kelvin-api-openapi.yml
- name: Simulateur DPE
  description: >-
    A narrower calculator estimating a dwelling's DPE class and the class gain
    achievable from a given set of works.
  url: https://www.go-kelvin.com/simulateur-dpe
  distribution: hosted
- name: Iframe de sélection de polygone
  description: >-
    An interactive map component that lets a user pick their building visually and
    yields the latitude, longitude and ban_id required by POST /api/v3/simulations. The
    API description points integrators at it directly — it is the intended companion to
    the simulation-creation endpoint, not an optional extra.

    mechanism: HTTP Basic authentication
    checked: '2026-08-14'
    note: >-
      The component's documentation sits behind HTTP Basic auth even though the API
      reference that links to it is public. An integrator reading the public spec is
      told to use a component whose documentation they cannot open.
- name: Calculateurs gratuits
  description: >-
    Free, no-account web calculators kelvin hosts on its marketing site: CEE amount per
    work gesture, MaPrimeRénov' amount by income and works, and a CEE-delegatee
    directory. Hosted pages, not embeddable components.

    kelvin documents delivering qualified leads into a customer's CRM "via Zapier ou
    API". No public Zapier app listing exists (zapier.com/apps/kelvin/integrations
    returns 404 as of 2026-08-14), so the connector appears to be private or
    invite-only. The documented Zapier payload fields — simulation id, creation date,
    contact details, property type, address, Google Maps link, simulation URL, gclid and
    fbclid — match the Simulation + Client + TrackingContext entities in
    data-model/kelvin-data-model.yml.
