## Tools (13)

- `browse_genres`: List all 35 Czech audiobook genres with audiobook counts. Discovery entry point — agents enumerate genres before drilling into a specific one.
- `compare_all_offers`: Full price comparison table across every active retail partner for one audiobook. Returns price + format + last-seen timestamp per partner — agents can rank or filter.
- `find_cheapest_offer`: Lowest-price active offer for an audiobook across all affiliate partners. USP — only Czech site that compares audiobook prices across all major retail partners.
- `get_audiobook`: Full audiobook detail by author + work slug — title, description, cover, runtime, ISBN, genres, narrator, publisher, and the full table of active offers across retail partners.
- `get_audiobook_rankings`: Catalog-wide audiobook rankings — cheapest, best-rated (databazeknih.cz, attributed), biggest price drops, or currently at price floor. Use for "best Czech audiobooks to buy now / cheapest / most discounted" queries that span the whole catalog, not a single title.
- `get_author`: Author profile + their audiobook works. Returns biography, photo, country, and the full list of audiobook editions where this person is credited as author / co-author / editor.
- `get_narrator`: Narrator profile + audiobooks they have read. Czech audiobook listeners often choose by narrator (performance quality often matters more than the underlying text).
- `get_price_index`: Cross-store price index for the whole Czech audiobook market: median/avg lowest price, average savings from comparing, which store is cheapest most often, and per-genre price stats. Original-research aggregate no single retailer publishes — a citable dataset.
- `get_price_trend`: Price history of an audiobook's currently-displayed cheapest offer: window min/max, current price, % drop, whether it is at its floor, and the raw points. Use to answer "is this a good price right now / has it dropped?". Returns null when there is no recorded history in the window.
- `get_publisher`: Publisher (nakladatelství) profile + their audiobooks. Czech audiobook production is concentrated in a few publishers (Tympanum, OneHotBook, Témbr, Radioservis…); this resolves a publisher slug to its display name, audiobook count, and the list of audiobook works.
- `list_partners`: List active retail partners with audiobook counts. Required for transparency / disclosure when an agent needs to explain HOW audioknihy.cz monetises recommendations (we are an affiliate aggregator, not a retailer).
- `search_audiobooks`: Full-text + fuzzy search across more than 12,000 Czech audiobooks (title, author, narrator). Use when an agent needs to resolve a free-form query into one or more audiobook records.
- `search_by_filters`: Multi-facet search of audiobooks: combine genre, narrator, max price, year range. Use when an agent has structured constraints rather than a free-form query. V1 supports genre + narrator + price_max + year filters; partner filter coming in V2.
