  Cross-cutting request/response conventions for the MotionElements Marketplace
  API v2 — authentication, pagination, sorting, localization/currency
  parameters, and the list-envelope shape that apply across every operation.

base_url: https://api.motionelements.com/v2
api_style: REST over HTTPS, JSON responses

authentication:
  scheme: HTTP Basic (API secret key as username, empty password)
  key_source: Developer Console (https://www.motionelements.com/developer/app)
  transport: HTTPS only
  detail: authentication/motion-elements-authentication.yml

pagination:
  style: page-number
  request_params:
    page: Page number, default 1
    per_page: Results per page, default 100
  response_fields:
    object: "\"list\" for paginated collections"
    page: Current page number
    per_page: Items returned per page
    total_count: Total number of matching items
    data: Array of result objects

sorting:
  param: sort
  format: "comma-separated field list; prefix a field with `-` for descending"
  example: "sort=credits,-created_at (credits ascending, then created_at descending)"

localization:
  language:
    param: language
    values: [en, ja, ko, zh-hant]
    note: ISO 639-1 language code in lowercase
  currency:
    param: currency
    values: [USD, EUR, JPY, KRW, TWD]
    note: ISO 4217 currency code in uppercase; affects returned price/credits

idempotency:
  supported: false
  note: >-
    The published API is read-dominant (search + reference lookups) with a
    single PATCH on /account; no idempotency-key header is documented.

error_envelope:
  note: >-
    Errors surface via standard HTTP status codes (401 on missing/invalid
    secret key, 404 on unknown element/media-type). A dedicated documented
    problem schema was not published in the collection.

rate_limit_signaling:
  note: No rate-limit headers or quota policy are documented in the public collection.
