search_encyclopediaFind metals, minerals, ingredients and materials, potions, gems, the milieux, animals, plants and creatures of Biomes and the reference pages of Hearth, Passage and Bearer by name (case- and accent-insensitive; exact names first, then prefixes, then substrings, aliases included). Returns each hit with its kind, id, one-line summary and page url; call get_entry for the full data.
get_entryThe full data of one entry (a metal, mineral, ingredient, potion, gem, milieu, animal, plant, creature or reference page) by its id (from search_encyclopedia or list_entries): properties, lore, page url, embed_url.
list_entriesA page of one catalogue, filtered. Use it to answer "which minerals are cubic and gem-quality?", "legendary metals of the medieval era", "swamp ingredients with a fire essence". Combine with q for a name search inside the filter.
random_entryOne entry at random among those matching the filters: loot tables, "mineral of the day", a credible metal for a blacksmith, a foraging roll.
list_facetsEvery distinct value of each filterable field of a catalogue (categories, rarities, crystal systems, biomes, essences…) and its entry count.
craft_rulesThe rules of the crafting system (characters, essences, extraction, brewing, gem cutting, socketing) as titled HTML sections.
search_tracksPublished tracks of MGS Audio (music, ambiences, sound effects) with composer, album, moods, keywords, duration and page url. Metadata only: no audio file. "A battle theme" → genre: "Combat", type: "music"; "a forest ambience" → type: "ambience", genre: "Forest"; "something for a dungeon" → keyword: "dungeon".
random_trackOne published track at random among those matching the filters.
get_trackOne track by id or slug, with its published alternative versions.
list_composersEvery composer with published tracks, most prolific first, with their page url.
list_albumsPublished albums with track count, page url and an embeddable player url.
audio_taxonomyThe vocabulary of the track filters: every genre, mood, era and keyword in use.
