  source: >-
    Enhancements API Evangelist derived for the Lokki External API from the published documentation at
    docs.getlokki.com, Lokki's own Agent Skill, and live probes of
    https://prod.api.eu-west-3.lokki.rent on 2026-08-17. The original specification, fetched verbatim
    from https://docs.getlokki.com/api-reference/openapi.json, is never mutated — every change lives
    here as an Overlay 1.0.0 action.

  description: >-
    Name the two environments. The published spec lists staging.api.eu-west-3.lokki.rent and
    prod.api.eu-west-3.getlokki.com with no descriptions; the documentation names the production host as
    prod.api.eu-west-3.lokki.rent. Both production hosts resolve and both are Lokki-owned domains, so
    the overlay records all three rather than choosing for the provider.
  update:
  - url: https://prod.api.eu-west-3.lokki.rent
    description: Production — the host named in the documentation, the authentication example and the Agent Skill.
  - url: https://prod.api.eu-west-3.getlokki.com
    description: Production — the host named in the published spec's servers[] block. Same product, Lokki-owned domain, but not the host the docs tell partners to call.
  - url: https://staging.api.eu-west-3.lokki.rent
    description: Staging — test data. Requires a lokki_sk_test_ key; production keys are rejected.
- target: $.components.securitySchemes
  description: >-
    Record the header discrepancy. The spec declares x-access-token; the documentation, the
    getting-started page and Lokki's Agent Skill all specify x-api-key, and the Skill lists the wrong
    header name as a known cause of 401. Do NOT silently rewrite the provider's scheme — add the
    documented one alongside and flag it.
  update:
    x-api-key:
      type: apiKey
      in: header
      name: x-api-key
      description: >-
        The Access Token header specified by https://docs.getlokki.com/api-reference/authentication.
        Keys are environment-bound (lokki_sk_test_ for staging, lokki_sk_live_ for production) and are
        issued by a Lokki representative. Scoped at domain, action and route level; a key missing the
        required scope returns 403.
- target: $.components.securitySchemes['x-access-token']
  description: Annotate the spec's own scheme with what it appears to be.
  update:
    x-note: >-
      Declared in the published partner spec, and also the header the internal Dashboard API uses for
      its JWT. The partner documentation specifies x-api-key instead. See
      authentication/lokki-authentication.yml.
- target: $.paths['/v2/external/stores'].get
  description: Add the missing error responses. The published spec declares only a 200 on all seven operations; 401, 403, 404 and 429 are all reachable.
  update:
    responses:
      '401':
        description: No access token, an invalid token, or the token sent under the wrong header name.
      '403':
        description: 'The token lacks the domain/action/route scope for this endpoint. Observed body: {"statusCode":403,"message":"Forbidden resource","error":"Forbidden"}.'
      '429':
        description: Rate limit exhausted. Undocumented; the API host emits x-ratelimit-limit / x-ratelimit-remaining / x-ratelimit-reset.
- target: $.paths['/v2/external/stores/{slug}/items'].get
  description: Record that from/to change the MEANING of pricing and stock, not just their values, and add the missing error responses.
  update:
    x-state-dependent-fields:
      pricing.basis: LOWEST_PRICE without from/to, RANGE_COMPUTED with them.
      pricing.price: '"Starting from" (lowest available) without from/to; computed for the window with them.'
      stock.availableQuantity: Maximum theoretical stock without from/to; real availability for the window with them.
    responses:
      '401':
        description: No access token, an invalid token, or the token sent under the wrong header name.
      '403':
        description: The token lacks the domain/action/route scope for this endpoint.
      '404':
        description: Unknown store slug. Resolve the slug from GET /v2/external/stores first.
- target: $.paths['/v2/external/stores/{slug}/items/{itemId}'].get
  description: Same state-dependent pricing/stock semantics on the single-item read.
  update:
    x-state-dependent-fields:
      pricing.basis: LOWEST_PRICE without from/to, RANGE_COMPUTED with them.
      stock.availableQuantity: Maximum theoretical stock without from/to; real availability for the window with them.
    responses:
      '401':
        description: No access token, an invalid token, or the token sent under the wrong header name.
      '403':
        description: The token lacks the domain/action/route scope for this endpoint.
      '404':
        description: Unknown store slug or item id.

    Point the 21 deprecated flat properties at their modular replacements, so a code generator or agent
    reading only the spec can migrate without reading the prose guide.
