It supports managing projects, clusters, backups, restores, data imports, billing, and private endpoint connections across both TiDB Cloud Serverless and TiDB Cloud Dedicated tiers. The API uses HTTP Digest Authentication with public and private API keys and returns JSON-formatted responses. Available as both v1beta and the newer v1beta1 versions, it enables automation of database infrastructure lifecycle management at scale.
