    method: 'POST',
    headers: {
      "API-KEY": "text",
      "Content-Type": "application/json"

    }),
});
const data = await response.json();

Response

200

{
  "request_id": "5e2edad6d5154daf",
  "code": 200000,
  "message": "Success",
  "data": {
    "address": "0x3d12e63d4313f850d23cead57ef0c29e94c9551d",

        ]
      }
    ],
    "name_tag": "Binance_Deposit_0x3d12"
  }
}

Note: If the address you are querying does not have labels on the specified blockchain, the API will return label information from compatible chains for that address.

For instance, if you request the label information for the address "0xae4a7cde7c99fb98b0d5fa414aa40f0300531f43"on the Ethereum chain and we do not have label information for this address on Ethereum, the API will check for label information on EVM-compatible chains. If label information exists for this address on any compatible chains, the API will return the address labels from all compatible chains.

Note: This operation will count as a single API call, and you will not be charged multiple points for returning information from multiple compatible chains.

Request parameters:

{
  "chain_id": 1,
  "address": "0xae4a7cde7c99fb98b0d5fa414aa40f0300531f43"
}

                ]
            }
        ]
    }
}

You can notice that the response structure includes an additional compatible_chains field, which stores information about the address on compatible chains. This field is structured as an array, containing the label information of the address on multiple compatible chains.
