Verify physical products
The developer API for Endstate - give every physical product a secure digital identity, and confirm it’s authentic the moment a user taps its NFC chip.
Quickstart
Run a full verification in minutes using a test chip - no hardware
required.
Core concepts
Collections, units, real NFC chips, and how verification ties them
together.
Verify a unit
The production flow with real NTAG 424 DNA chips, end to end.
Core SDK
The Endstate API in TypeScript - typed operations, typed errors, and
retries derived from the spec.
