BetaCompany data from the Iowa business register, through the Topograph API.
Topograph reads Iowa Secretary of State, Business Services Division and returns the company profile, legal representatives and other key persons of Iowa companies through one API.
What comes back for each datapoint and document, as on the coverage matrix.
Requests run in prefill mode (fast) or verification mode (the authoritative register answer).
Comes back in Verify.
A company profile typically comes back from the register in 1 s in prefill mode and 6 s in verification mode.
These are typical observations, not a service-level commitment: set your timeouts well above them.

Official Iowa business entity register maintained by the Business Services Division of the Iowa Secretary of State. Covers every domestic and foreign entity registered under Title XII of the Iowa Code: for-profit and nonprofit corporations (Chapter 490 and Chapter 504), limited liability companies (Chapter 489), limited partnerships and limited liability partnerships (Chapters 486A, 486B, 488), cooperative associations (Chapters 497-499), multiple-housing cooperatives (Chapter 499A), state-chartered banks (Chapter 524), savings & loan associations (Chapter 534), and insurance companies (Chapters 508-515). Each entity is assigned a six-digit corp_number with leading zeros preserved (e.g. 084726) that serves as the primary identifier across every register lookup. Topograph exposes two complementary integrations. First, the monthly open-data extract published at data.iowa.gov (~339k active entities), used for sub-second prefill lookups and the bulk pipeline. Second, the live business search portal at sos.iowa.gov/search/business, which covers every entity in the register (active and inactive), exposes authoritative status, the full officer roster (Name, role, Director flag, address), and serves the printable Trade Register Extract.
