The IOST API is a high-performance blockchain platform designed to be scalable, stable, and customizable. IOST's account-permission system relies on public-private key pairs which allow for multiple account systems per user. The API offers several technical endpoints associated with nodes, chains, blocks, and contracts. This API returns JSON formatted responses.
Thirteen APIs have been added to the ProgrammableWeb directory in categories including Blockchain, Events, Transcription, and Sports. One highlight is the Europeana Record API for retrieving data about Europe's art and historical artefacts. Here's a rundown of the latest additions.
