**Provider:** Etcd — https://apis.io/providers/etcd/  
**Documentation:** https://etcd.io/docs/v2.3/api/

etcd v2 HTTP API is one of 10 APIs that [Etcd](https://apis.io/providers/etcd/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Deprecated, HTTP, Key-Value, and REST. The published artifact set on APIs.io includes API documentation.

The original etcd v2 API exposed a RESTful HTTP interface for key-value operations using a hierarchical directory structure. This API has been deprecated in favor of the v3 gRPC API and was removed from the default etcd build in later versions. Existing users should migrate to the v3 API.
