Address Label API

The Address Label API enables users to fetch address labels and comprehensively understand an address from various perspectives. It currently supports more than 25 different blockchains, including Solana, Bitcoin, Tron, Ethereum, BSC and other EVM-compatible chains.

Address Label

When using our API to look up an address, we will return three types of labels to describe the address.


We use Entity to describe an address's owner or controller. If it's an EoA address, this means the entity that controls this EoA address (with the private key). For a smart contract, the entity can refer to their deployers (projects).

An address may have more than one entity.

Assigning an entity to an address is primarily to establish a connection between a cryptocurrency address and a known organization or individual. However, there are cases where an address can be associated with multiple entities. In these cases, we will assign the Main Entity and Complementary Entities.

For instance, consider Alameda's deposit address on Binance. We can state that Binance exercises control over the private key of this address or that Alameda utilizes it. In such situations, we designate Binance as the primary entity for this address while considering Alameda as a secondary or complementary entity.

Entity Category

Most entities are organizations or services, while only a few represent individuals. Most entities are categorized into the following categories, which can help you understand their nature.


We use Attribute to describe the behavior or action associated with a specific address or entity. All attributes are listed in the table below.

Name Tag

A name is utilized to describe a cryptocurrency address with human-readable information. Assigning names usually considers the entity associated with the address and its specific attributes, such as Binance Hot Wallet 1 or Vitalik 2.

Supported Networks

The Address Label API supports 25 different chains, which are listed in the chart below. We also provide an API that allows you to retrieve a list of all supported chains, enabling you to stay informed about any newly added chains.

When making an API request, please use the Chain ID to specify the desired chain.
