Tagging Meta Data

Coin Metrics Tagging Data is a powerful tool that provides users with a unique lens on blockchain data. It allows you to access blockchain addresses labeled with their real-world entity names or functions. By associating blockchain-level accounts/addresses with meaningful labels, you can gain a deeper understanding of the cryptocurrency world. The applications for this data can better explain activity around hot spots like smart contracts, exchanges, miners and many more.

For accessing our Dictionary of tags you can leverage our Tag Catalog API Call. This returns a list of the tag options that can then be used ti query in the tags parameter of our /tagged-entities response. For detailed definitions or methodologies relating to specific tags. Please reach out to our team.

Example: https://api.coinmetrics.io/v4/blockchain-metadata/tags?&api_key={api_key}

When utilizing the Tagging Data there are two query methods. The first is by searching for an Entity. Entities are addresses, accounts or contracts.

Example: https://api.coinmetrics.io/v4/blockchain-metadata/tagged-entities?entities={entity_list}&pretty=true&api_key={api_key}

The second query method is for retrieving all entities defined under a defined tag. In the first release you are able to query for a single address.

Example: https://api.coinmetrics.io/v4/blockchain-metadata/tagged-entities?tags={tag_list}&pretty=true&api_key={api_key}
