## Tools (5)

- `get_data_freshness`: Get metadata about when this dataset was last calculated and what period
of sale/rental data it covers. Call this before presenting any number as
'current' - the underlying data is refreshed monthly, not in real time.
- `get_sample_data`: Get free sample data - real (not synthetic) district and project stats
for a small fixed set of examples, in the exact same shape as the paid
tools. Use this to verify the data fits your use case before calling
the paid tools, which cover the full catalogue of districts and projects.
- `list_condo_projects`: List condo/apartment projects we track, optionally filtered by district.
Free - use this to discover valid project names before calling the paid
stats/yield tools, rather than guessing at spelling.
- `list_hdb_towns`: List every HDB town we track, with the specific flat types available
for each. Free - use this to discover valid town names and flat types
before calling the paid get_hdb_town_stats tool.
- `list_landed_projects`: List landed house projects/estates we track, optionally filtered by
district. Free - use this to discover valid names before calling the
paid stats/yield tools.
