Know Your Business (KYB) verification allows you to verify company identity, ownership structure, and legal standing through document analysis and public registry checks.

​
Verification methods

Dataspike KYB API provides two verification methods:
  • Document Verification — upload and verify corporate documents (certificates of incorporation, shareholder certificates) to extract and validate company information and shareholder details.
  • US Company Registry Check — look up a company in the US Secretary of State registry by name or SOS ID to verify its registration status, registered agent, and formation details.

​
How it works

All KYB operations are asynchronous. When you submit a verification request, the API immediately returns a request_id with status initial. You then poll for the result using the request ID. 
1. POST  /api/v4/kyb/:applicant_id/verify-document     →  { request_id, status: "initial" }
   POST  /api/v4/kyb/:applicant_id/us-registry-check   →  { request_id, status: "initial" }

2. GET   /api/v4/kyb/result/:request_id                 →  { request_id, status: "verified", response_data: {...} }
