List Company Merges

Access Level Required: Requires Standard Access (Level 1).

Duplicate-company merges, oldest first.

When two records turn out to describe the same issuer we retire one and keep the other. The retired id disappears from the company list, so a warehouse built by incremental sync would otherwise keep the stale row forever. Poll this feed to reconcile.

Poll updated_at_from, not merged_at_from. Merges can be reversed, and a reversal edits the existing record in place rather than adding a new one — it moves updated_at but never merged_at. A reversed_at on a record you already ingested means the merge no longer holds and shell_id is a live company again.

Results are ordered by merged_at then id, so paging is stable even when a bulk merge writes several records in the same instant. Records are never deleted from this feed.

Covers merges recorded since 2026-06-29. Earlier cleanups predate this log and are not represented; companies removed by hard deletion rather than merge do not appear here either.
