SIC Codes UK

jackmmaher/siccodes.co.uk

You'd reach for this when working with UK company data or need to translate between classification systems. It wraps the siccodes.co.uk API to look up Standard Industrial Classification codes, map them to GICS or ICB equivalents, and search across 5.6 million Companies House records. The 731 SIC codes cover everything from agriculture to IT services, so if you're building financial analysis tools, compliance workflows, or market research automation that touches UK businesses, this handles the taxonomy heavy lifting. Available over stdio for local workflows or streamable HTTP for remote deployments.
