# F5 BIG-IP Application Services Templates (FAST)

**Canonical:** https://apis.io/apis/f5/f5-big-ip-fast/  
**Provider:** F5 — https://apis.io/providers/f5/  
**Base URL:** https://{bigip}/mgmt/shared/fast  
**Documentation:** https://clouddocs.f5.com/products/extensions/f5-appsvcs-templates/latest/

F5 BIG-IP Application Services Templates (FAST) is one of 22 APIs that [F5](https://apis.io/providers/f5/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include BIG-IP, Application, Templates, Declarative, and Automation. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and a changelog.

FAST is the templating layer over AS3 — 26 operations over /mgmt/shared/fast for template sets, templates, applications, tasks and settings. It is the most agent-friendly F5 API in the estate for one specific reason: GET /templates/{setName}/{templateName} returns a real machine-readable parameter schema, and POST /render returns the AS3 declaration a set of parameters WOULD produce without deploying it, so an integration has both an input contract and a rehearsal step.
