Tools as reported by the server

• search_offenders
  Search US sex-offender registries for one person and/or location. Fans out across all 58 registries (or the ones named in `jurisdictions`), de-duplicates people across registries, scores each match, and returns the normalized records. Supply whatever identifiers you have — all args are optional but
• batch_search
  Run many person/location lookups in one call (row-in / row-out). Each row goes through the SAME engine as search_offenders, so a row's records are identical to what a single search would return. A row that fails is reported with status='error' in place and never aborts the batch. Max 1000 rows. Retu
• get_registry_coverage
  List every registry we cover plus its scope, legal status, and health. Public coverage catalog (no API key required). Use it to discover the `jurisdictions` codes accepted by search_offenders / batch_search and to check per-registry freshness/health before relying on a result. Returns: { count, regi
• search_criminal
  Search US criminal records — county jail bookings, state prison custody, court cases and warrants. Covers county jail rosters, statewide prison systems, court sources, warrant systems and statewide registries across the states, DC and the territories, plus the federal layer — which is a separate sys
• get_criminal_coverage
  List the criminal-record jurisdictions searched, with kind and status. Use it to discover which states and counties are reachable and which are answering today, before relying on an empty result. Depth is uneven by design: counties publish independently, so a state with many county jurisdictions is
• map_viewport
  Get what to draw for one map view: clusters, pins, or named pins. Send the view as `bbox`, or as `lat` + `lng` + `radius_miles`. The detail returned depends on the zoom the view is answered at (the response states it in `zoom`): - zoom 3-12 -> mode 'clusters': a count per grid cell. Each cluster has
• map_area
  Get what to draw inside a drawn shape: a polygon, or a line with a buffer. The same answer as map_viewport for the shape's bounding box, limited to what is inside the shape, at the same detail levels (clusters, pins, or named pins at zoom 15+). The response adds `shape: 'polygon' | 'route'`. Returns
• map_route
  Exact counts of registered addresses along one walking or bus route. Counts a corridor either side of the line, a radius around each stop, or both, and returns exact numbers per leg and per stop with nameless pins and their distances. Never an estimate and never partial: the answer is complete or th
• map_group
  List the people behind a many-people pin or an approximate-area pin. Returns: { total, page, perPage, totalPages, kind: 'address' | 'area', named, members: [ { id, addressType, label, housingStatus, hasPhoto } ] }. Members carry `label` only when the group id came from a view at zoom 15 or closer (`
• map_open_record
  Open the complete record behind one map marker, or behind a saved reference. Returns: { record, recordRef, billing: { billed, unit, reason }, notice }. `record` is the same Record object search_offenders returns. `recordRef` ('mr_...') is a lasting reference: keep it to open the same record later, a
