The cannabis industry is growing and evolving, with more countries and states legalizing marijuana for recreational use. As a result, there is a need for up-to-date resources about pot, including e-commerce websites selling cannabis products and online databases like APIs that help growers find a market for their harvest. A weed API is an online structure that allows an application to interact with information on a server, providing data such as product information, strain data, and drug patent information. Several cannabis APIs have been reviewed, including Otreeba Open Cannabis API, Neobi Open Cannabis API, MAPI US API, Strain API, DrugPatentWatch API, and Lexigram API. These APIs offer varying levels of functionality and pricing, with some being free and others requiring paid plans. The target audience for a weed API includes pot shops, growers, and hobbyists who want to connect with potential customers and access information about new strains, flavors, and effects.
