## Coverage

FR

## Use when

- Track how French awarded public-contract volumes and amounts evolve month by month or year by year.

## Avoid when

- Use procurement/fr/market for a current segment overview without a time series.
- Use procurement/fr/search for open tender opportunities.

## Limitations

- The current partial month or year can mechanically reduce the latest period.

## Example queries

- Show monthly French public-procurement trends for CPV 641 over 24 months.
