Server tool list (4)
Raw names from tools/list. Only developers need these.
| world_at_year | List states, empires and cultures with an OpenHistoricalMap border snapshot in a given year, optionally overlapping a region. Coverage is incomplete; an empty result does not establish historical absence. |
| find_polity | Look up a state or empire by name or any of its Wikidata labels and aliases (substring, case-insensitive), or by Wikidata QID. Returns its lifespan, every border snapshot with its bounding box, and links. |
| search_events | Search map events: battles (Wikidata), UCDP armed-conflict events since 1989, volcanic eruptions VEI 4+ (Smithsonian GVP), significant earthquakes (NOAA), witnessed meteorite falls, and UNESCO World Heritage sites (undated). Month/day bounds match only events recorded at least that precisely; undated heritage sites match only searches without a date bound. Results are sorted by date. |
| create_video_link | Build a link that opens RewindMap's short-video maker preloaded with a map clip: borders (and optional event layers) changing from one year to another over a place, with an optional title and map labels. The visitor opens the link and taps Download to get a watermarked MP4 (vertical 9:16 for Shorts/Reels/TikTok, or landscape). Rendering happens in the visitor's browser; this tool returns the link only, never a video file. |
