## Coverage

FR

## Use when

- You need explainable administrative changes recorded in historized Sirene periods for one company.

## Avoid when

- You need BODACC legal notices; use company/fr/events or company/fr/legal-announcements-search.

## Limitations

- Only change flags explicitly provided by Sirene are returned; business events are not inferred.
- Sirene exposes one change indicator for the three usual-denomination fields; when it changes, the post-change values of all three fields are returned.
