Data Sources

Missouri data is sourced from the Missouri Secretary of State — Business Filings register, the official register of every entity formed or qualified to do business in Missouri. The register returns legal name, Business Identification Number, entity type, status, formation date, domestic/foreign classification, home jurisdiction, registered agent, multiple office addresses, and a full filing history. The same source serves both mode: "onboarding" and mode: "verification" requests.
No bulk feed. Missouri does not publish a bulk dataset, so every lookup queries the register directly.

Quirks & Gotchas

No ownership filings. Missouri does not require LLCs or corporations to publish owner, member, manager, or officer information. The only legal-representative record consistently published is the registered agent. Officer and owner rows are populated almost exclusively for Fictitious Name registrations.
Registered Agent fallback. When a foreign entity has lapsed its registered agent, the register displays Secretary of State as the agent of record. Topograph treats that value as “no agent on file” and returns an empty otherKeyPersons array.
Placeholder addresses on legacy records. A small number of entities filed before the SOS migrated to the current system (e.g. credit unions chartered in the 1930s) carry the literal placeholder No Address to Migrate <City>, <State> in the address field. Topograph surfaces the state code in legalAddress.region and leaves addressLine1, city, and postalCode undefined on those records.
