On August 4, 2016, a new standard called GraphQL was introduced for defining, querying, and documenting APIs in a human-friendly way. It includes built-in documentation, a friendly query language, and various tools to assist users. Buildkite has been using GraphQL extensively for front-end development through its public endpoint (graphql.buildkite.com). The explorer at graphql.buildkite.com/explorer uses GraphiQL, an open-source project that provides a code editor with auto-complete and inline documentation. To use the explorer, users need a Buildkite account and API Access Token. A basic example of a GraphQL query is provided to request the name of the current user.
