US Certificate of Good Standing Extraction API

Overview

The Certificate of Good Standing Extraction API parses state-issued Certificates of Good Standing into structured JSON. These certificates are minimal documents that confirm an entity is legally registered and in good standing with a state authority (e.g., Delaware Secretary of State). The API is designed for KYB and onboarding use cases where institutions need to store evidence of good standing, extract the entity name, and validate the issuing authority and date.
