Description

Lookup or search Singapore companies and entities via the Accounting and Corporate Regulatory Authority (ACRA) dataset on data.gov.sg. Returns entity name, UEN (Unique Entity Number), registration date, entity type, status, and registered address. Monthly refresh — data is current to within one month.

Two variants: lookup by UEN (/sg/company/{uen}) and name search (/sg/company/search/{name}). Note: some queries return 503 with best_effort: true due to ACRA rate limiting from Railway IPs.
