What is Zapper API?
The Zapper API skill provides a streamlined interface for AI agents to interact with multi-chain blockchain data. By leveraging this Openclaw Skills integration, developers can programmatically access comprehensive wallet data, including DeFi positions, NFT floor prices, and token balances across more than 50 different networks.
This skill transforms complex GraphQL queries into simple, actionable commands, enabling real-time financial analysis and portfolio management. Whether you need to check a single balance or audit a complex web of DeFi positions, this tool integrates seamlessly into your automated workflows.
Zapper API Use Cases
- Monitoring multi-chain wallet balances and 24-hour price movements.
- Auditing DeFi positions including liquidity pools, lending, and staking.
- Valuating NFT collections based on current floor prices.
- Tracking recent transaction history for tax or compliance purposes.
- Identifying unclaimed rewards across multiple protocols.
How Zapper API Works
- The user provides a wallet address or a pre-configured wallet label to the agent.
- The skill authenticates with the Zapper GraphQL API using a provided API key.
- The tool executes specific queries based on the requested command such as tokens, apps, or nfts.
- Data is aggregated from across 50+ supported chains including Ethereum, Base, and Solana.
- The results are formatted for the user or returned as raw JSON for further processing within the Openclaw Skills ecosystem.
Zapper API Setup
First, obtain an API key from the Zapper Dashboard. Then, configure your environment or create a local configuration file.
Set the environment variable:
export ZAPPER_API_KEY="your-api-key"
Or create a configuration file at ~/.config/zapper/addresses.json:
{
"apiKey": "your-api-key",
"wallets": [
{"label": "Main", "address": "0x..."},
{"label": "DeFi", "address": "0x..."}
]
}
