Wallet History JSON-RPC Methods

Constructing Requests

Option 1: You can use the JSON RPC playground to easily create sample JSON RPC requests.

Option 2: Alternatively, you can construct your own requests by following the below steps:

Log into the CDP Portal and go to the Data page.
Ensure the correct network in your RPC URL based on the supported RPC networks.
Open a terminal and make your requests based on the supported methods in this API reference page.

Authentication

For information on how to authenticate requests to our JSON-RPC APIs, please visit the Client API Keys section of our Authentication page.

JSON-RPC Methods for Wallet History Data

`cdp_listBalances`

This endpoint retrieves the latest balances for an address. Note that this JSON RPC endpoint provides a more complete list of assets than the CDP API. However, there is a few seconds of delay in terms of data freshness for indexing a complete list of assets. If you need more real-time data with whitelisted assets, you should use the CDP API.

The API credit value of this method is 100.

Parameters

Name	Type	Req	Description
address	string	Y	Blockchain address hash. EVM chain address hash should be lowercase.
pageSize	string	N	Number of balances to receive in a page. The default value is 25. The maximum value is 100, and values supplied over this will be coerced to the maximum.
pageToken	string	N	Provided from a previous response’s nextPageToken

Returns

Field	Description
asset.id	The identity of the asset for querying for details or history.
asset.type	The type of Asset the definition describes. For example: “native”, “erc20”, “erc721”, “erc1155”, “creditAlphanum4”, “fa2”.
asset.groupId	The contract address or group identifier for an Asset. For an NFT or a multi-token Asset this may identify a group of Asset. For a native Asset this will not be set.
asset.subGroupId	The identifier that distinguishes the identity of the Asset within the contract address or group. For an NFT or a multi-token Asset that can have many Assets associated with a contract address, this could be a token ID. For a UTXO, this could be the coin identifier.
value	The amount of the balance in the lowest denomination of the asset. Type is in BigInteger in standard base64 encoding.
valueStr	The string representation of the balance value to avoid precision loss.
decimals	The number of decimals the asset utilizes.
nextPageToken	A token which can be provided as `pageToken` to retrieve the next page. If this field is omitted, there are no additional pages.
