We outline the first stable release of the specification, v1.0, which is already supported by many leading databases and several software packages. We illustrate the advantages of the OPTIMADE API through worked examples on each of the public materials databases that support the full API specification.Multidisciplinary SciencesScience & Technology - Other Topicscrystallography open databaseopen-access collectionhigh-throughputinfrastructureaflowlib.orginterfacerobusttext::journal::journal article::research article
