Shipping an API shouldn't take five vendors

A gateway here, a billing integration there, a portal you hand-build, analytics you bolt on, and cold outreach for distribution. Weeks of undifferentiated work before your first paying customer.

One platform. One login. One bill.

Every piece of the API lifecycle, pre-integrated — so the same identity flows from gateway traffic to analytics to billing to your marketplace listing.

Six modules, one platform

The full API lifecycle — create, run, monetize, and distribute — with nothing to integrate yourself.

API Marketplace

A public directory where you list your API and consumers discover, try, and subscribe. Distribution and demand, built in.

/marketplace

API Gateway

Managed auth, rate limiting, routing, caching, and versioning across regions. No infrastructure to run or scale.

/gateway
❯_

Developer Portal

Docs auto-generated from your OpenAPI spec, an interactive “try it” console, keys, and SDKs — branded as yours.

/portal
$

Monetization & Billing

Meter usage and price it any way — per-call, tiered, subscription, freemium. Invoicing, tax, and payouts handled.

/billing

Analytics & Observability

Real-time traffic, latency, errors, revenue, and top consumers — with alerting and searchable logs.

/analytics

Design & Build

Import or design an OpenAPI spec, mock endpoints, and validate before you publish. The create step, in the box.

/design
POST /apis 201 Created

Live in an afternoon

Three steps from spec to paying customer. No procurement, no glue code.

Design & publish

Point APIGang at your endpoint or upload an OpenAPI spec. We generate docs, a portal, and keys instantly.

Set your pricing

Choose per-call, tiered, or subscription pricing with a free trial. Metering and invoicing are wired automatically.

Reach buyers

List on the marketplace and get discovered by developers already searching for what you built. You get paid; we handle payouts.

GET /marketplace/apis 200 OK

A marketplace of demand

Every listing is a discovery channel. Buyers subscribe and pay with a single APIGang account — providers get customers without cold outreach.

Point tools can’t build a marketplace

01

Two-sided network effects

More providers attract more buyers, and more buyers attract more providers — a flywheel a standalone gateway or billing tool doesn’t have.

02

One source of truth

Traffic, identity, billing, and docs live together, so there’s no drift between what you meter, show, and charge.

03

Value before the network

The gateway, portal, and billing are useful on day one — you don’t wait for scale to get the benefit.

Questions, answered

Do I have to move my API to APIGang’s servers?+

No. APIGang sits in front of your existing API as a managed gateway. You point us at your endpoint; your code stays where it is.

How does billing and payout actually work?+

We meter every request through the gateway, apply the pricing you set, invoice your customers, handle tax, and pay you out — through an established payments provider, so there’s no money-movement code for you to build.

Is my API usable before the marketplace has scale?+

Yes. The gateway, developer portal, and billing deliver value on their own. The marketplace is an added distribution channel, not a prerequisite.

What about security and compliance?+

Encryption in transit and at rest, tenant isolation, DDoS protection, RBAC, and audit logging are built in, with SOC 2 Type II and GDPR/DPA tooling on the roadmap for regulated buyers.

Can I bring my own OpenAPI spec?+

Absolutely. Import an existing spec to auto-generate docs, an interactive console, and SDKs — or design a new one in the Design & Build module.
