13F filer search

Discovery surface for 13F filers. Search by name, CIK, or LEI; filter by filer_type / aum_tier; optionally restrict to filers passing the modelability gate. Per-filer follow-up calls under /13f/filers/{bw_filer_id}/* are metered.

Authentication: None — this endpoint is public. Like /funds/search, it is wrapped in withBilling with skipBilling: true, which bypasses key validation entirely. Billing: Free Rate Limit: 60 requests/minute per IP (FILER_SEARCH_IP_RPM). limit is capped at 100 rows.
