Retrieve subsidiaries disclosed in an issuer’s latest available 10-K Exhibit 21
Audience: application and coding agent.

​
Coverage and source scope

Use this route to review subsidiaries an issuer disclosed in Exhibit 21 of its latest available 10-K. The result is an extracted filing schedule, not a current legal-entity registry, complete ownership chart, or confirmation that an issuer has no other subsidiaries. An empty list can mean the selected filing lacks a usable Exhibit 21. Preserve the returned accession, filing date, and request metadata when presenting the default result; filingUrl is included only in agent view. See filing conventions and freshness and source evidence.

​
Agent mode

Pass ?view=agent to receive the compact agent shape: per-subsidiary fields (name, jurisdiction, ownershipPercent) + envelope citation fields (accessionNumber, filingDate, filingUrl). filingUrl is exclusive to the agent response; the default response returns accessionNumber and filingDate without it. 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
