summary: >-
  Cross-cutting request/response conventions for the Datanomik OpenBanking and Treasury
  APIs, captured from the developer documentation and the harvested OpenAPI. Datanomik is
  a read-mostly open-finance data API secured with HTTP Basic API keys; there is no
  documented idempotency-key contract.
authentication:
  style: http-basic
  detail: secretId / secretPassword API keys sent as HTTP Basic auth
  ref: authentication/datanomik-authentication.yml
pagination:
  style: page-number
  params:
    page: zero-based page number
    size: page size (rows per page)
  example: GET {baseUrl}/v1/transactions?page=0&size=100
  source: https://docs.datanomik.com/reference/authentication-copy
idempotency:
  supported: false
  notes: >-
    No idempotency-key header or parameter is documented in the API reference or the
    OpenAPI. Most operations are GET reads; writes (create-manual-transaction, sync
    assets) do not advertise an idempotency contract.
