description: Eurostat APIs are fully free of charge and require no payment, subscription, or financial commitment. All costs are borne by the European Commission as part of Eurostat's public-service mandate. FinOps considerations are limited to infrastructure costs on the consumer side.
cost_model:
  type: free
  price_per_request: 0
  price_per_gb: 0
  authentication_required: false
  api_key_required: false
  registration_required: false
consumer_cost_considerations:
  - description: Egress/bandwidth costs from your own cloud infrastructure when consuming Eurostat API responses at scale
    mitigation: Cache responses locally; data updates only twice daily so caching is highly effective
  - description: Compute costs for parsing SDMX-ML (XML) responses, which are verbose
    mitigation: Use JSON-stat or SDMX-CSV formats for lighter payloads; use Statistics API for JSON-stat output
  - description: Engineering time to handle asynchronous API polling for large dataset extractions
    mitigation: Implement exponential backoff on status polling; consider bulk TSV downloads for full datasets
optimization_tips:
  - Use sinceTimePeriod and untilTimePeriod parameters to fetch only needed time ranges
  - Use geoLevel parameter (country, nuts1, nuts2, nuts3) instead of explicit geo lists to avoid long URLs
  - Cache dataset structure metadata (DSDs, codelists) separately from data — structure changes infrequently
  - For recurring large extractions, prefer bulk TSV download files over API queries
  - Use the Catalogue API to discover datasets before querying, avoiding unnecessary large requests
