Amazon SNS

Amazon Simple Notification Service (SNS) is a fully managed messaging service for both application-to-application (A2A) and application-to-person (A2P) communication. It enables pub/sub, SMS, email, and mobile push notifications.

agent ready

Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.

Kin Score

API Evangelist profiles Amazon SNS the way a machine reads it — 115 machine-readable artifacts across 8 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 — Amazon SNS scores 62.2/100 (strong), with a separate agent-readiness read of 54/100 (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 Amazon SNS

Each block below is one kind of artifact we hold for Amazon SNS. 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 8

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.

Amazon SNS ?Action=ListTagsForResource API

The ?Action=ListTagsForResource API from Amazon SNS — 1 operation(s) for ?action=listtagsforresource.

Amazon SNS ?Action=TagResource API

The ?Action=TagResource API from Amazon SNS — 1 operation(s) for ?action=tagresource.

Amazon SNS ?Action=UntagResource API

The ?Action=UntagResource API from Amazon SNS — 1 operation(s) for ?action=untagresource.

Amazon SNS Platform Applications API

Operations for managing platform applications used for mobile push notifications via APNs, FCM, and other push services.

Amazon SNS Publishing API

Operations for publishing messages to SNS topics or directly to endpoints. Messages can be plain text or structured JSON for per-protocol delivery.

Amazon SNS SMS API

Operations for managing SMS messaging attributes and phone number opt-out lists.

Amazon SNS Subscriptions API

Operations for subscribing endpoints to topics, confirming subscriptions, listing subscriptions, and unsubscribing. Subscriptions define which endpoints receive messages publish...

Amazon SNS Topics API

Operations for creating, listing, configuring, and deleting SNS topics. Topics are communication channels to which messages are published and from which notifications are delive...

Open Collections 1

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).

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.

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.

Features 6

The notable capabilities this provider advertises, captured as structured features so they can be searched and compared instead of read one landing page at a time.

Notable capabilities this provider offers.

Pub/Sub Messaging

Fan-out messages to multiple subscribers through topics supporting HTTP/S, email, SQS, Lambda, and SMS protocols.

FIFO Topics

Strict message ordering and exactly-once delivery for use cases requiring sequence-preserving fan-out.

Message Filtering

Subscription filter policies enabling subscribers to receive only the messages relevant to them.

Mobile Push Notifications

Cross-platform mobile push via APNs, FCM, and other push services through platform applications.

SMS Messaging

Direct SMS text messaging to phone numbers worldwide with support for transactional and promotional messages.

Dead-Letter Queues

Capture undeliverable messages for analysis and reprocessing to ensure no messages are lost.

Event Specifications 1

Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

AsyncAPI definitions for this provider's event-driven and streaming APIs.

Semantic Vocabularies 1

JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.

JSON Schema 28

Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

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.
