AWS CloudFormation

A collection of APIs provided by AWS for infrastructure as code provisioning and management of AWS and third-party resources using CloudFormation templates and the Cloud Control API.

agent ready

Reference-quality API operations across every facet — a rich contract, published governance, transparent operations, and machine-readable commercial terms.

Kin Score

API Evangelist profiles AWS CloudFormation the way a machine reads it — 158 machine-readable artifacts across 13 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.

Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — AWS CloudFormation scores 75.3/100 (exemplar), with a separate agent-readiness read of 60/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile AWS CloudFormation

Each block below is one kind of artifact we hold for AWS CloudFormation. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

APIs 13

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Individual APIs this provider publishes, each with its own machine-readable definition.

Operations for creating and managing change sets to preview stack changes.

AWS CloudFormation Exports API

Operations for listing stack exports and imports.

AWS CloudFormation Registry API

Operations for managing extension types in the CloudFormation Registry.

AWS CloudFormation Request Status API

Operations for tracking the status of asynchronous resource operations and cancelling in-progress requests.

AWS CloudFormation Resources API

CRUDL operations for creating, reading, updating, deleting, and listing cloud resources through a uniform interface.

AWS CloudFormation Stack Drift API

Operations for detecting and describing configuration drift.

AWS CloudFormation Stack Events API

Operations for retrieving stack-related events.

AWS CloudFormation Stack Instances API

Operations for managing stack instances within a stack set.

Postman Collections 2

A runnable collection turns the contract into something a developer can execute in seconds. We profile them because the fastest way to trust an API is to make a real call against it.

Ready-to-run Postman collections for exercising this provider's APIs.

Open Collections 2

Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.

Open, tool-agnostic API collections (OpenAPI-derived and Bruno).

Arazzo Workflows 9

Real integrations are rarely a single call. Arazzo describes the multi-step sequences — auth, then create, then confirm — so both a human and an agent can follow the choreography, not just the endpoints.

Multi-step API workflows described with the Arazzo specification.

CloudFormation Audit Cross-Stack Exports

List the account's stack exports, then list the stacks that import a named export.

ARAZZO

CloudFormation Create and Execute a Change Set

Create a change set, poll until CREATE_COMPLETE, execute it, then wait for the stack update to finish.

ARAZZO

CloudFormation Deploy a Stack Set

Create a stack set, roll out an instance to an account and region, then poll the instance until CURRENT.

ARAZZO

CloudFormation Detect Stack Drift

Start drift detection, poll until detection completes, then list the drifted resources.

ARAZZO

CloudFormation Inspect a Stack Resource

Describe a single stack resource, then run targeted drift detection against just that resource.

ARAZZO

CloudFormation Provision a Stack

Validate a template, create a stack, poll until CREATE_COMPLETE, then list its resources.

ARAZZO

CloudFormation Review and Clean Up a Change Set

Create a change set, poll until it is computed, then branch — delete it when it contains no changes, otherwise keep it for review.

ARAZZO

CloudFormation Safe Stack Update

Summarize a template, update the stack, poll until UPDATE_COMPLETE, then pull the stack events.

ARAZZO

CloudFormation Tear Down a Stack

Disable termination protection, delete the stack, then poll until DELETE_COMPLETE.

MCP Servers 1

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

Pricing Plans 1

Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.

Published pricing tiers and plan structures.

Rate Limits 1

Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.

Documented rate limits and quota policies.

Cloudformation Rate Limits

FinOps 1

Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

Examples 34

Real request and response payloads are what turn a spec from abstract into obvious — and they're one of the twelve things an agent needs to call an API correctly on the first try.

Security Posture 4

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Agentic Access 1

An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
