In today’s fast-evolving cryptocurrency landscape, managing multiple digital asset accounts across centralized exchanges (CEXes), decentralized platforms (DEXes), and blockchain wallets can be overwhelming — especially for developers building financial applications. That’s where a powerful, unified API solution becomes essential. Whether you're creating a portfolio tracker, wealth management tool, or analytics dashboard, accessing accurate and up-to-date account balance data is critical.
Enter a seamless way to aggregate crypto account balances from diverse sources through a single integration. This streamlined approach allows developers to retrieve real-time and historical balance information across major CEXes, blockchains, and self-custody wallets — all in both native crypto and converted fiat values.
👉 Discover how easy it is to integrate real-time crypto balance data into your app.
Why Unified Balance Data Matters
Users today hold assets across multiple platforms — from Binance and Coinbase to MetaMask and Trust Wallet. Without a centralized data aggregation method, applications must build individual connections to each service, leading to increased development time, maintenance overhead, and inconsistent data quality.
A modern API solves this by offering a standardized interface that normalizes data from hundreds of sources. You get clean, structured responses containing total account value, individual asset holdings, transaction histories, and automatic fiat conversions — eliminating the complexity of multi-source integrations.
Key Features of Crypto Balance Aggregation
Real-Time & Daily Balance Updates
Stay current with live balance tracking that reflects the latest transactions and price movements. The API supports both instant polling and scheduled updates, ensuring your application displays accurate financial snapshots whether used for daily monitoring or real-time trading analysis.
Multi-Source Account Integration
Support for major centralized exchanges, blockchain networks, and crypto wallets means users can link all their accounts in one place. From Ethereum-based DeFi wallets to exchange accounts on Kraken or KuCoin, the system pulls balance data seamlessly.
Automatic Fiat Value Conversion
Understanding portfolio performance requires context — and that often means seeing crypto holdings in familiar fiat currencies like USD, EUR, or JPY. The API automatically converts balances using reliable market rates, supporting a wide range of fiat pairs for global usability.
Historical Balance Tracking
Go beyond today’s numbers. Access historical balance data from the moment a user connects their account. This enables long-term performance tracking, net worth trend analysis, and personalized investment insights — ideal for robo-advisors or financial reporting tools.
Comprehensive Transaction History
Retrieve detailed transaction records including deposits, withdrawals, trades, and smart contract interactions. Each entry comes with timestamps, amounts in both crypto and fiat, and status details, giving you full visibility into user activity.
How It Works: Retrieve Account & Balance Data
To access user account information, use the GET /account/:account_id endpoint. This returns a structured JSON response containing all relevant balance and status details.
Here's an example of what the response includes:
{
"id": "603522490d2b02001233a5d6",
"resource_type": "account",
"blockchain": null,
"created_at": 1630412605283,
"updated_at": 1630412605283,
"fiat_value": "4321.98",
"fiat_ticker": "USD",
"status": "ok",
"status_details": {
"date": "2022-07-14T12:51:29.370Z",

}
],
"balances": [
{
"ticker": "BTC",
"provider_ticker": "BTC",
"name": "Bitcoin",
"asset_is_verified": null,
"asset_type": null,
"amount": "0.20210831",
"decimals": 8,
"fiat_value": "2021.08",
"fiat_ticker": "USD",
"logo": "https://data.wealthica.com/api/securities/CRYPTO:BTC/logo",
"updated_at": 1630412605283,
