API and implementation snapshot
The API supports single and bulk validation with bearer token authentication and straightforward JSON responses. Teams can integrate the API into sign-up forms, tenant screening tools, admissions workflows, and account creation gates with minimal engineering overhead.
Check ID SA is a format and encoded-data validator, not a government-record match service. That makes it a practical first-pass validation layer in broader compliance and identity workflows.
