What is Zapper?
The Zapper skill provides a powerful bridge between AI agents and on-chain financial data. By leveraging Zapper's comprehensive GraphQL API, this integration allows users to monitor multi-chain asset balances, DeFi positions like liquidity pools or staking, and NFT collections without switching between multiple explorers. It serves as a unified data layer for anyone building automated financial workflows or portfolio management tools within the Openclaw Skills ecosystem.
This skill is essential for developers and users who need a high-level view of assets across ecosystems like Ethereum, Base, Polygon, Arbitrum, and many others. It simplifies the complexity of interacting with diverse blockchain protocols by providing a standardized way to retrieve human-readable financial data.
Zapper Use Cases
- Portfolio tracking to aggregate all DeFi positions and balances across multiple chains.
- Yield hunting by checking for claimables and unclaimed rewards across protocols.
- NFT portfolio management to track holdings across various marketplaces.
- Generating human-readable transaction history for on-chain activity logs.
- Performing quick token price lookups for real-time market analysis.
How Zapper Works
- The skill initializes by validating the ZAPPER_API_KEY from the local configuration file.
- When a command is triggered, the skill constructs a specific GraphQL query tailored to the requested data (e.g., tokens, apps, or transactions).
- It sends an HTTP POST request to the Zapper public GraphQL endpoint using curl.
- The raw JSON response is processed through jq and python3 for efficient parsing and formatting.
- The final refined data is presented to the user or coding agent to facilitate informed decision-making.
Zapper Setup
To use this within Openclaw Skills, obtain an API key from the Zapper Dashboard. Then, create the configuration directory and save your credentials:
mkdir -p ~/.clawdbot/skills/zapper
cat > ~/.clawdbot/skills/zapper/config.json << 'EOF'
{
"apiKey": "YOUR_ZAPPER_API_KEY"
}
EOF
