What this means for your integration
Ingestion is automatic on every release. Your code never has to know the calendar — but if you poll, these dates are when polling pays.
From the official release to your response
/inflation/latest. Poll cheaply — every response ships ETag, so If-None-Match turns unchanged data into a 304.Missing months stay missing. If the government doesn't publish (e.g. October
2025, federal shutdown), the API serves the hole as null — never an
estimate.
