# Temporal

**Canonical:** https://apis.io/providers/temporal-io/  
**Website:** https://temporal.io/  
**APIs profiled:** 8

Temporal is a durable execution platform for orchestrating long-running, fault-tolerant workflows. Its primary API surface is gRPC - the WorkflowService, OperatorService, and (on Temporal Cloud) the Cloud Operations API are defined as protobuf in github.com/temporalio/api and github.com/temporalio/cloud-api. Temporal also ships a first-party HTTP API: a grpc-gateway that maps a REST/JSON subset of the WorkflowService onto paths under /api/v1, for automation and environments where gRPC is impractical. Temporal is open source (MIT) and self-hostable, and is also available as the managed Temporal Cloud.
