Fanbase API
Build your world, powered by your fan data.
Fanbase API gives artists the building blocks to create fully custom, logged-in fan experiences on your own site or app.

Frequently asked questions
What is Fanbase API?
Fanbase API gives artists the building blocks to create fully custom, branded fan experiences on your own site or app, powered by your fan data. Fans log into your world, not ours.
What can you build with it?
Custom fan apps, membership portals, gamified experiences, fan clubs, fan-aware websites. YBHQ (Yungblud) and Kong Studios (Gorillaz) are the first live examples of what is possible when you build outside of the box on your own terms.
What's included?
Fan Login & Identity, Membership Tiers & Payments, Gated Content & Access, Fan Passes, Fan Referrals, Posts & Community, XP / Levels & Rewards, Personalization, and real-time data sync back to your Openstage fan graph. You also get sandbox access, full reference documentation, example repo access, and three onboarding sessions with our team.
Who is it for?
Artists with established fanbases who want more than a standard platform offers: full creative control, owned fan data, and a custom experience that reflects their world. Requires developer resources to build. If you have a dev team or agency partner and want to create a custom fan world that looks, feels, and functions exactly the way you want it, this is built for you. If you need Openstage to do the build, we can connect you with recommended partners.
How is this different from a fan club platform?
A fan club platform gives you their box. Fanbase API gives you the building blocks to build outside of the box and create your own world. Your domain, your brand, your UX, your rules. You are not limited by templates, shared interfaces, or someone else's feature roadmap. And unlike any standalone fan club tool, everything you build is natively connected to the most powerful fan data layer in music. The build layer and the data platform are the same system. Your world, powered by your fan data, delivering personalized fan experiences at scale.
Does Openstage build the experience?
No. Your team or a build partner designs and develops the front-end experience. Openstage provides the infrastructure, technical support, API versioning, and three onboarding sessions to help you define your goals, scope your build, and get to launch. If you need a recommended build partner, we can point you in the right direction.
Who owns the fan data?
You, the artist. Every fan interaction, inside the custom experience and across streaming, social, and live, feeds into a unified fan graph that you own and keep forever.
How long does it take to launch?
It depends on what you are building. Teams adding fan login and interactivity to an existing site can be live in a few weeks. A full custom fan world with memberships, gamification, and a branded experience typically takes longer depending on your team's resources and scope. Our onboarding sessions are designed to help you scope realistically from day one.
What does onboarding look like?
Three sessions with a clear endpoint. Session 1 is strategic visioning: what to build and why. Session 2 is scoping: mapping your fan experience to Fanbase API capabilities. Session 3 is roadmap and handoff to your partner or in-house team. After that, execution belongs to your team. Openstage provides ongoing account management, feedback, and bug support. Not builds.
What does it cost?
Fanbase API is a premium add-on available exclusively on the Legendary Plan. Book a demo and we will walk you through what that looks like for your setup.
Build your world. Not someone else's.
