What is Zerion API Skill?
The Zerion API Skill enables AI agents to interact with comprehensive on-chain data through the Model Context Protocol (MCP). By leveraging Zerion's indexed data, this skill provides developers and researchers with a unified interface to query over 50 EVM-compatible chains and Solana. It simplifies the complexity of blockchain data by providing interpreted results for portfolio values, transaction histories, and DeFi protocol interactions. This tool is essential for building Openclaw Skills that require deep financial insights or real-time blockchain monitoring. Users can easily track assets, evaluate PnL, and analyze cross-chain activity without manual block explorer navigation.
Zerion API Skill Use Cases
- Researching specific wallet addresses (0x format) to understand holding patterns and asset distribution.\n- Analyzing complex DeFi positions and protocol usage across multiple blockchain networks.\n- Retrieving real-time token prices and historical charts for market analysis and comparison.\n- Investigating transaction history with human-readable parsed actions instead of raw hex data.\n- Monitoring gas prices across different chains to optimize transaction timing and costs.\n- Conducting competitive analysis by exploring top holder distributions and protocol stickiness.
How Zerion API Skill Works
- The user provides a wallet address or token query to an AI agent configured with Openclaw Skills.\n2. The skill connects to the Zerion remote MCP server using a secure API key provided during setup.\n3. Zerion's indexing engine retrieves and interprets the raw blockchain data for the requested query across multiple chains.\n4. The interpreted data (e.g., total portfolio value, active DeFi stakes, or PnL) is returned to the agent in a structured format.\n5. The AI agent presents the synthesized financial data to the user or uses it to perform automated research tasks.
Zerion API Skill Setup
- Obtain an API key from the Zerion Developer Portal at https://developers.zerion.io.\n2. Add the Zerion configuration to your MCP settings file, ensuring you include your Bearer token in the headers.\n\n
json\n{\n \"zerion\": {\n \"url\": \"https://developers.zerion.io/mcp\",\n \"headers\": {\n \"Authorization\": \"Bearer YOUR_API_KEY\"\n }\n }\n}\n\n3. Verify connectivity by running a test query such as "Get portfolio for 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045".
Zerion API Skill Data Schema & Taxonomy
| Entity | Attributes Description |\n|--------|------------|\n| Portfolio | Total wallet value, chain-specific breakdown, and currency denominations. |\n| Transactions | Hash, timestamp, parsed actions (swap, send, receive), and chain ID. |\n| DeFi Positions | Protocol name, asset quantity, current value, and staking/yield data. |\n| Token Prices | Current market price, historical price points, and market capitalization. |\n| Gas Prices | Fast, Standard, and Slow rates across different EVM chains and Solana. |
Zerion API Skill Advanced Features
- Multi-chain aggregation: Unified views of assets across 50+ EVM chains and Solana in a single request.\n- Human-readable transactions: Automatically parses complex smart contract interactions into clear, understandable actions.\n- Real-time indexing: Direct access to live on-chain data without the latency of typical block explorers.\n- Remote MCP support: Lightweight integration that doesn't require local node hosting or heavy client libraries for Openclaw Skills.\n- PnL Calculation: Built-in logic for calculating realized and unrealized profit and loss on various positions.
