IYK API is published by [IYK](https://apis.io/providers/iyk/) on the [APIs.io](https://apis.io/) network. Tagged areas include Chips, Chip Groups, Item, Refs, and Taps. The published artifact set on APIs.io includes API documentation, an API reference, a getting-started guide, and authentication docs.

The IYK API provides primitives for building digi-physical experiences. Core endpoints manage chips (NFC tags such as NTAG 424, KONG, and ARX HaLo), chip groups, items, taps/refs (validated physical interactions with replay protection), OTP codes (30-minute one-time passwords for NFT transfers and minting), and phygitals. Module endpoints cover POAP Events and Guestbook Events, and a Self-Service surface manages POAP devices. Authentication is via an x-iyk-api-key request header.
