Omnicost is a construction cost catalog and estimating tool. It gathers unit prices for materials, labor and equipment from 208 sources such as public tenders and supplier catalogs, and keeps the source and observed date on every price. Coverage is strongest in Spain, the United States and the European Union. You can search prices or let the AI assistant draft an estimate, then adjust each line and export it. Developers and AI agents get the same data through a REST API and an MCP server.
