## Tools (7)

- `battlefield_search`: List or search England's registered historic battlefields (from Hastings-era sites to the Civil War): name with battle year, date registered, area in hectares, grid reference and official link. For history fans, schools and walkers asking where a battle was fought. Source: Historic England Register of Historic Battlefields. Covers only the registered sites in England, not every recorded battle. (cost: 1 credit)
- `historic_park_garden_search`: Search England's Register of Parks and Gardens of Special Historic Interest by name: grade, date registered, area in hectares and official link. For garden visitors, estate owners and planners (registration is a planning consideration). Source: Historic England National Heritage List for England. Name match only; covers registered landscapes, not every public park. (cost: 1 credit)
- `listed_building_lookup`: Look up one listed building by its NHLE list entry number (the 7-digit reference used in conveyancing and planning papers): name, grade, listing and last-amended dates, grid reference and official link. Source: Historic England National Heritage List for England. Covers listed buildings only; a number belonging to a scheduled monument, park, battlefield or wreck returns found: false. (cost: 1 credit)
- `listed_building_search`: Search England's listed buildings by name and get list entry number, grade (I, II*, II), listing date, grid reference and the link to the official Historic England record. Useful for homebuyers, conveyancers, builders and planners asking 'is this building listed'. Source: Historic England National Heritage List for England. Matches the list entry name only (often the address or building name as written when listed), not street addresses generally; England only, and it does not cover conservation areas or local lists. (cost: 1 credit)
- `protected_wreck_search`: List or search wrecks designated under the Protection of Wrecks Act 1973 in English waters: name, designation date, restricted area in hectares, position (lat/lon and grid reference) and official link. Diving on or interfering with a designated wreck inside its restricted area without a Historic England licence is an offence, so divers and boat users check here. Source: Historic England National Heritage List for England. Covers designated wrecks only (not all wrecks or military remains); the position is a reference point, not the restricted-area boundary. (cost: 1 credit)
- `scheduled_monument_search`: Search England's scheduled monuments by name and get list entry number, date scheduled, area in hectares, grid reference and official link. Scheduling gives legal protection: works, and metal detecting, on a scheduled monument need consent. For landowners, detectorists, developers and walkers. Source: Historic England National Heritage List for England. Name match only; most archaeology is not scheduled, so no match does not mean a site is unprotected or unrecorded. (cost: 1 credit)
- `scheduled_monuments_near`: List scheduled monuments around a point in England, nearest first, with date scheduled, area and the official link. Answers 'are there any scheduled monuments on or near this land' for development checks and metal-detecting permission. Source: Historic England National Heritage List for England. Takes lat/lon; includes any monument whose mapped area overlaps the search square, with distance to its reference point rather than its edge. (cost: 1 credit)
