GET /v1/companies/subsidiaries

Return the list of subsidiaries extracted from the latest 10-K Exhibit 21 for a given entity
Audience: application and coding agent.

​
Agent mode

Pass ?view=agent to receive the compact agent shape: per-subsidiary fields (name, jurisdiction, ownershipPercent) + envelope citation fields (accessionNumber, filingDate, filingUrl). The lineage metadata block is dropped. The per-item shape is already narrow, so this endpoint is an API-consistency win rather than a byte-size win — reduction is approximately 0% but the agent envelope matches the contract exposed by every other agent-mode endpoint. See api conventions → response formats for the full ?view= contract.

​
Failure posture

  • treat non-2xx responses as contract-aware failures, not free-form errors
  • preserve requestId and traceparent in logs and downstream reports
  • if provenance or freshness metadata is present, return it unchanged so trust is not lost in the handoff
