TAGBASE is trust infrastructure for physical objects. We give every item an uncopyable, easily verifiable digital identity, so anyone can confirm a product is genuine with a single tap of their phone — no app required.
This documentation is for developers building on top of that foundation. It covers the concepts you need, a quickstart to your first integration, the solutions you can assemble, and the API reference.
What you can build
The platform exposes one identity layer that many kinds of solution sit on top of:
- Verify — TAGBASE’s own anti-counterfeiting product, built on this very platform. It’s the reference for what you can build, and you can use it ready-made.
- Custom — your own solution, built directly against the API the same way. That’s what this documentation is for.
The same tap-to-prove identity underpins a lot of ground: presence checks that confirm someone or something was somewhere at a given time, cashless payments at festivals, NFC signature stickers for signing documents, event access control, supply-chain track & trace, and digital product passports. Each is a different way of reading the platform’s trust signals.
How verification works
Each item carries a dynamic NFC tag bound to its digital identity. A tap produces scan data that your solution forwards to the platform; the platform validates it and returns a trusted verdict in milliseconds.
Where to start
- Resource model — how accounts, tags, sessions, and verifications relate.
- Get started — your first verification in three API calls.
- Building a solution — an end-to-end walkthrough on top of the platform.
