SureChem, traditionally a chemical patent search site, responded to its "customers' requests for a direct pipeline to patent chemistry data that gave them batch access, the ability to easily integrate with internal tools, and no limitations on how they accessed or use the data" with the launch of SureChemDirect. According to SureChem founder, Nicko Goncharoff, the SureChemDirect API "enables users to directly search [the SureChem] database" for chemical patents and chemical structures within their own toolkits.
