CoinGecko API Streamlines Multi-Chain Crypto Wallet Tracking

CoinGecko’s API offers a comprehensive solution for tracking crypto wallet transactions, balances, and profits and losses (PnL) across multiple blockchains. The service consolidates data from various networks into a single, easy-to-use interface, eliminating the need to query each chain separately.

Key features include the ability to pull token balances, trade histories, and token transfers for any wallet address. The Token Balances by Wallet Address endpoint provides a snapshot of all tokens held, valued in USD, across networks like Ethereum, Base, and Arbitrum. The Trades by Wallet Address endpoint details each trade, labeled as buy or sell, with USD pricing included. Meanwhile, the Token Transfers by Wallet Address endpoint captures token movements not visible in trade-only feeds.

Users can merge trades and transfers into a chronological activity feed, then add realized and unrealized PnL data from the PnL by Wallet Address endpoint. This integrated approach ensures a complete view of a wallet’s activity, including asset movements and trading performance.

To access these features, users need a CoinGecko API key on the Analyst plan or higher. The API supports over 250 networks and provides detailed responses, including USD pricing for trades and transfers, making it easier to calculate trade values without needing separate price feeds.
