About MPDS
MPDS is the Materials Platform for Data Science, a web platform providing machine-readable, critically evaluated inorganic materials data for materials-science AI work. Its GUI offers open access after login, with search by 15+ criteria, analysis tools, interactive plots, distinct phases and prototypes, and about 50k datasheets from 20k articles, described as under 5% of GUI access. Paid full GUI access adds detailed visualizations, datasheets, export in 5+ formats, high-quality redrawn phase diagrams, full references and DOIs, and about 3M datasheets from 400k articles.
API options provide machine-readable data as software as a service, with regular API and data updates, documentation, support and tutorials, OPTIMADE standard support, access to an MPDS materials ontology, and included full GUI access. Full API access is listed from €9,500 yearly for academia; enterprise options include unlimited GUI and API accounts, early access, integration into third-party products, OAuth, LDAP, managed cloud, local installation, and dedicated R&D as a service. Full GUI access is listed at €1,900 yearly per account.
