# HashiCorp Consul

**Canonical:** https://apis.io/providers/consul/  
**Website:** https://www.consul.io  
**APIs profiled:** 14

HashiCorp Consul is a distributed, highly available service-networking control plane that automates network configuration, discovers services, enables secure service-to-service communication, and exposes a strongly consistent key/value store. The Consul HTTP API is a REST + JSON service exposed by every Consul agent and server at /v1, gated by the X-Consul-Token header (apiKey) and ACL policies, supporting blocking queries via X-Consul-Index for streaming-style change detection.
