browse_transcriptions
Browse Transcriptions
Browse transcriptions hierarchically
Returns a hierarchical browse of available page transcriptions. Mirrors `/transcripties/lijst/`. Three modes, depending on the supplied filters: * No filter — top-level list of source archives ordered by total transcription count (descending). * `archive_code` — list of all archive numbers (archieftoegangen) within that archive, ordered by archive number. * `archive_code` + `archive_number` — list of all inventories within that archive number, ordered by inventory number. The order of items is fixed and cannot be overridden. Results are always returned in full (no paging).

The response includes the total filtered record count, the total number of distinct groups (capped at 750) and the top-N groups according to the chosen sort.
