ngrok

ngrok is a unified application delivery network for developers, providing secure tunnels, ingress-as-a-service, API gateway, and AI gateway capabilities. It enables developers to expose local services on the public internet, manage edge ingress, and route traffic to AI providers without redeploying applications. ngrok provides a unique URL for each tunnel, traffic policy controls, and a comprehensive REST API for programmatic management of all resources.

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 ngrok the way a machine reads it — 48 machine-readable artifacts across 24 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 — ngrok scores 68.5/100 (strong), with a separate agent-readiness read of 53/100 (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 ngrok

Each block below is one kind of artifact we hold for ngrok. 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 24

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.

ngrok Abuse Reports API

Abuse Reports allow you to submit reports of abusive endpoints.

ngrok Agent Ingresses API

Agent Ingresses are the addresses ngrok agents connect to.

ngrok API Keys API

API Keys are used to authenticate to the ngrok API.

ngrok Backends API

Backends define how traffic is handled, including tunnel group, weighted, failover, HTTP response, and static address backends.

ngrok Certificate Authorities API

Certificate Authorities are x509 certificates used for mutual TLS authentication.

ngrok Credentials API

Tunnel Credentials are authtokens used to start ngrok tunnels.

ngrok Edges HTTPS API

HTTPS Edges define HTTPS endpoints with routes and modules.

ngrok Edges TCP API

TCP Edges define TCP endpoints for non-HTTP protocols.

ngrok Edges TLS API

TLS Edges define TLS endpoints with TLS termination and mutual TLS.

ngrok Endpoints API

Endpoints represent the public URLs of active tunnels and edges.

ngrok Event Destinations API

Event Destinations define where event data is sent.

ngrok Event Subscriptions API

Event Subscriptions define which events trigger notifications.

ngrok IP Policies API

IP Policies contain rules to allow or deny traffic from IP ranges.

ngrok IP Policy Rules API

IP Policy Rules are CIDR-based allow/deny rules within an IP Policy.

ngrok IP Restrictions API

IP Restrictions apply IP Policies to specific ngrok resources.

ngrok Reserved Addresses API

Reserved Addresses are static TCP addresses for TCP tunnels.

ngrok Reserved Domains API

Reserved Domains are custom hostnames for HTTP/HTTPS/TLS tunnels.

ngrok SSH Certificate Authorities API

SSH Certificate Authorities manage keys for signing SSH certificates.

ngrok SSH Credentials API

SSH Credentials are public keys for authenticating SSH tunnel sessions.

ngrok SSH Host Certificates API

SSH Host Certificates authenticate ngrok tunnel servers to clients.

ngrok SSH User Certificates API

SSH User Certificates authenticate users to ngrok SSH tunnel servers.

ngrok TLS Certificates API

TLS Certificates are x509 certificate/key pairs used to terminate TLS traffic.

ngrok Tunnel Sessions API

Tunnel Sessions represent running ngrok agent connections.

ngrok Tunnels API

Tunnels represent individual tunnels within a tunnel session.

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.

Agent Skills 1

An agent skill packages the how-to for driving these APIs from an assistant — the prompts, the sequence, the guardrails — so the knowledge to use the API travels with it.

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.

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 12

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.

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.
