Freshness, provenance, and versioning

  • Knowledge cutoff: the current package is pinned to 2026-09-23. It is not a real-time feed.
  • Evidence: returned history records retain source attribution to the reviewed supporting source artifact.
  • Time: record effectiveAt describes when the underlying event or state applies, while version metadata describes when Grizzly Bulls recorded the knowledge.
  • Commercial boundary: the preview API serves only records that passed the reviewed extracted-facts commercial eligibility gate. Raw filing artifacts and internal rights-policy fields are not returned.
  • Editorial scope: inclusion in this API does not determine whether someone appears in an unrelated Grizzly Bulls editorial profile.

Current preview limitations

  • The current package is the reviewed SEC insider-wealth cohort. Billionaire and celebrity wealth records are not yet exposed through this commercial preview package.
  • Person search is available, but there is no company-to-insider discovery, bulk export endpoint, webhook, SDK, or GraphQL surface in the preview.
  • History is paginated. Free access allows up to 25 history records per page.
  • Private beta entitlements can still expire; self-service Free access does not.
  • There is no production SLA during the developer preview.

Tell us what blocks a real workflow

We care more about the workflow you are trying to complete than a wish list of endpoints. If you hit a blocker, include the endpoint, the job you were trying to do, and whether the missing capability prevents you from integrating.
