F5 BIG-IP Application Services Templates (FAST)

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.

F5 BIG-IP Application Services Templates (FAST) is one of 22 APIs that F5 publishes on the 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.

This API exposes 26 operations across 13 paths, organized into 5 resource areas, and defines 35 schemas. It is described by OpenAPI 3.0.0, at version 1.26.0.

Requests are made against a single base URL, http://localhost:8100/mgmt/shared/fast.

Where this information came from

This is an independent, third-party profile of F5 BIG-IP Application Services Templates (FAST), published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
