## Overview of Targeting Metadata

The `retrieve_targeting_metadata()` function helps you understand what targeting data is available in the archive. It provides information about:

- Available dates

- File sizes

- Data completeness

- Country coverage


## Basic Usage

```{r}
#| eval: false
library(metatargetr)

# Get metadata for Germany's 30-day data
metadata <- retrieve_targeting_metadata("DE", "30")

# View the metadata
print(metadata)
```

## Understanding the Output

The metadata includes:

- Country code

- Date stamps

- Timeframe information

- Data availability flags

## Using Metadata for Data Validation

```{r}
#| eval: false
# Check data availability before retrieval
metadata <- retrieve_targeting_metadata("DE", "30")

if (nrow(metadata) > 0) {
  # Data is available, proceed with retrieval
  historical_data <- get_targeting_db("DE", 30, metadata$ds[1])
}
