description: >-
  FinOps view of consuming the ENTSO-E Transparency Platform API. There is no
  vendor invoice at any usage level - the platform is a regulatory
  publication under EU Regulation 543/2013 and the API is free after
  registration. All cost of ownership therefore sits on the consumer side:
  the compute and storage to poll the API within its 400 requests/minute cap,
  parse IEC 62325 XML (and unzip the imbalance/outage archives), and retain
  history pulled in one-year-per-request windows. Teams building price-aware
  products (dynamic kWh tariffs, battery dispatch, balancing analytics)
  typically ingest each bidding zone daily after day-ahead publication and
  backfill history once, which keeps request volumes trivially small.
notes: >-
  Because rate and range limits - not billing - are the scarce resource,
  optimize for fewer, larger queries (full one-year ranges on backfills) and
  cache responses; re-polling published history yields identical documents.
  The File Library covers bulk needs without consuming API rate budget.

    Track request counts per documentType and bidding zone against the
    400/minute cap; alert on 429 bans and on Acknowledgement 999 responses
    that indicate wasted polling of unpublished data.
- name: Allocation
  description: >-
    If multiple internal teams share one security token, meter and allocate
    the request budget per pipeline; consider separate registrations per
    team to isolate rate budgets.
- name: Optimization
  description: >-
    Cache aggressively - published market documents are immutable; backfill
    in maximal one-year windows; schedule day-ahead price pulls once after
    the daily publication instead of polling; use the File Library for bulk
    history.
- name: Accountability
  description: >-
    Assign an owner per ingest pipeline; review polling schedules against
    actual publication cadences so free data does not turn into avoidable
    infrastructure spend.
