Full property detail
bun run skills/boligsiden/cli/src/cli.ts detail <caseID> [--format json|plain]
Price history for a listing
bun run skills/boligsiden/cli/src/cli.ts timeline <caseID> [--format json|table|plain]
Location autocomplete
bun run skills/boligsiden/cli/src/cli.ts locations --text "<query>" [--limit 10] [--format json|table|plain]
List municipalities
bun run skills/boligsiden/cli/src/cli.ts municipalities [--limit n] [--format json|table|plain]
How to use effectively
Start with locations to get the right slug. The search commands require exact Danish location names. Use locations --text "<query>" first to resolve what the user typed into a valid slug before passing it to --municipalities or --cities.
Natural workflow: search → detail → timeline. Use search (or rentals/sold) to get a list of matching caseIDs, then call detail <caseID> to inspect a specific property, and timeline <caseID> to see its full price history.
Format choice matters.
--format table gives a quick human-readable overview — use this for summaries and comparisons.--format json (default) is best for data processing or when you need to extract specific fields.--format plain is ideal for single-record detail views (detail, timeline).
Pagination: --limit vs --per-page.
--per-page controls how many results the API returns per request (server-side).--limit caps the total results the CLI outputs regardless of what the API returned (client-side).- Use
--limit for quick overviews; use --page + --per-page for iterating through large result sets.

|---|
json | Programmatic use, default for all commands |

All errors are written to stderr as { "error": "...", "code": "..." } and the process exits with code 1.
Notes
- All data comes from the public
api.boligsiden.dk REST API — no credentials required.
- Pagination is 1-indexed (
--page 1 is the first page).
--limit caps the number of results returned by the CLI regardless of what the API returns.- Property type values use English slugs (e.g.
condo, not ejerlejlighed); use locations to resolve Danish place names.
