## Tools (16)

- `check_vehicle_by_vin`: Free vehicle history check against the official Czech vehicle registry (Registr silničních vozidel) by 17-character VIN: owner count and ownership timeline (companies named with IČO, private persons anonymous), STK inspection history with results, import origin, deregistration episodes, seized-document flags and technical specs. The registry has NO mileage data and NO license-plate lookup. Unknown VINs fall back to a rate-limited live registry lookup without timelines.
- `estimate_valuation`: Estimate a fair price range (min/median/max) for a specific car from comparable listings.
- `get_company_fleet`: One Czech company's registered fleet profile by IČO: vehicles owned now and ever, vehicles OPERATED (e.g. leased fleets), median holding period, owner-type classification (dealer / leasing / company / OSVČ), the paginated fleet list incl. former holdings, and its vehicles currently for sale on the market.
- `get_deal`: Get full detail for one deal by its deal id: listing, price history, market stats, prediction and why it is a deal.
- `get_market_overview`: Comprehensive market snapshot for a country: price pulse and direction, buyer/seller verdict, fuel & body-type & brand breakdowns, deal hotspots, 90d price trend, supply/freshness, oversupply and fast-mover signals.
- `get_market_trend`: Current median/avg price, listing count and 7d-vs-30d trend for one brand+model.
- `get_price_history`: 90-day daily price history (median, avg, count) for a brand+model, optionally narrowed by fuel.
- `get_price_movers`: Segments (brand+model+fuel) whose median price moved most over ~30 days, filtered to credible moves (volume floors, 5–30% band, sample-stability guard). Each is annotated with a credibility-weighted moverScore (rewards volume and a stable sample over raw magnitude).
- `get_weekly_summary`: This week at a glance: number of new deals, the single best deal, and average savings.
- `list_brands`: Brands that currently have active deals, with deal counts. Accepts the same filters as search_deals.
- `list_countries`: Countries/markets that currently have active deals, with counts.
- `list_hot_deals`: Top deals right now, ranked by deal score (biggest discount vs market first).
- `list_models`: Models for a given brand that currently have active deals, with counts.
- `list_recently_reduced`: Deals whose price was recently cut (1–40% drop between the two latest prices).
- `search_company_fleets`: Search Czech companies by name or IČO in the vehicle registry and get their fleet size (vehicles held now / ever). Sole traders (OSVČ) are only findable by exact IČO, never by name.
- `search_deals`: Search below-market used-car deals with filters (brand, model, price, year, mileage, fuel, body type, country, discount). Paginated; returns each deal with its listing, market stat, deal score and % below median.
