# How to check if Human Unreadable Act II is claimed

The primary collection of Human Unreadable is the Artblocks collection here:

* https://etherscan.io/address/0x99a9b7c1116f9ceeb1652de04d5969cce509b069
* https://opensea.io/collection/human-unreadable-by-operator

Token IDs range from 455000000 to 455000399

The secondary collection of Human Unreadable Act II is the contract here:

* https://etherscan.io/address/0x15878df6bf7a5da17e12ba80f1a635211f3dbae4
* https://opensea.io/collection/human-unreadable-choreographic-scores

The token IDs for the primary token and secondary token are identical. To check if an Act II token has been claimed you can check `ownerOf` on the secondary token contract. If it reverts, it has not been claimed. If it returns an address it has been claimed.

*Example not claimed*


*Example claimed*


## Alternative option

We can also provide an api hosted at `act2-api.operator.la` which returns a simple true/ false if the token has been claimed or not.
