+### How to find the network, datatoken address, and data NFT address from an Ocean Market link?
+
+If you are given an Ocean Market link, then the network and datatoken address for the asset is visible on the Ocean Market webpage. For example, given this asset's Ocean Market link: [https://odc.oceanprotocol.com/asset/did:op:1b26eda361c6b6d307c8a139c4aaf36aa74411215c31b751cad42e59881f92c1](https://odc.oceanprotocol.com/asset/did:op:1b26eda361c6b6d307c8a139c4aaf36aa74411215c31b751cad42e59881f92c1) the webpage shows that this asset is hosted on the Mumbai network, and one simply clicks the datatoken's hyperlink to reveal the datatoken's address as shown in the screenshot below:

+### How to use Aquarius to find the chainID and datatoken address from a DID?
+
+If you know the DID:op but you don't know the source link, then you can use Ocean Aquarius to resolve the metadata for the DID:op to find the `chainId`+ `datatoken address` of the asset. Simply enter in your browser "[https://v4.aquarius.oceanprotocol.com/api/aquarius/assets/ddo/](https://v4.aquarius.oceanprotocol.com/api/aquarius/assets/ddo/did:op:1b26eda361c6b6d307c8a139c4aaf36aa74411215c31b751cad42e59881f92c1)\<your did:op:XXX>" to fetch the metadata.
+
+For example, for the following DID:op: "did:op:1b26eda361c6b6d307c8a139c4aaf36aa74411215c31b751cad42e59881f92c1" the Ocean Aquarius URL can be modified to add the DID:op and resolve its metadata. Simply add "[https://v4.aquarius.oceanprotocol.com/api/aquarius/assets/ddo/](https://v4.aquarius.oceanprotocol.com/api/aquarius/assets/ddo/did:op:1b26eda361c6b6d307c8a139c4aaf36aa74411215c31b751cad42e59881f92c1)" to the beginning of the DID:op and enter the link in your browser like this: [https://v4.aquarius.oceanprotocol.com/api/aquarius/assets/ddo/did:op:1b26eda361c6b6d307c8a139c4aaf36aa74411215c31b751cad42e59881f92c1](https://v4.aquarius.oceanprotocol.com/api/aquarius/assets/ddo/did:op:1b26eda361c6b6d307c8a139c4aaf36aa74411215c31b751cad42e59881f92c1)
