The key is not stored in the MCP connector settings — the user must provide it each chat session. ### Workflow At the start of any Zerion-related task, if no API key has been provided yet, ask: "To query Zerion, I'll need your API key. You can find it at https://dashboard.zerion.io/. Please paste it here." Store the key in memory for the duration of the conversation. Never write it to files, display it in artifacts, or log it. Pass the key to the MCP server or REST calls as described below. ### Auth Format Zerion uses HTTP Basic Auth: the API key is the username, password is empty. Authorization: Basic Example: key zk_dev_abc123 → base64 of zk_dev_abc123: → emtfZGV2X2FiYzEyMzo= ### MCP Connection The Zerion API MCP server is at https://developers.zerion.io/mcp. When using MCP tools directly (outside artifacts), pass the API key as required by the tool parameters. When building artifacts that call the Anthropic API with MCP, include the key in the inner prompt so the inner Claude can authenticate: mcp_servers: [ { type: "url", url: "https://developers.zerion.io/mcp", name: "zerion-mcp" } ] Important: In artifacts, receive the API key as a prop or state variable — never hardcode it. Example pattern: // User inputs key via a secure input field (type="password") const [apiKey, setApiKey] = useState(""); // Pass key to inner Claude prompt so MCP calls authenticate const prompt = \`Using the Zerion API key: ${apiKey}, get portfolio for wallet 0x...\`; ### 1. Wallet Portfolio Overview Prompt the inner Claude to call the Zerion API for the wallet's portfolio: Get the portfolio for wallet {address} in USD. Include total value, daily changes, and distribution by chain and position type. Endpoint: GET /v1/wallets/{address}/portfolio currency: usd (default), eth, btc, eur, etc. filter[positions]: only_simple (default), only_complex (DeFi), no_filter (all) ### 2. Wallet Token Positions List all fungible positions for wallet {address}, sorted by value descending. Endpoint: GET /v1/wallets/{address}/positions/ filter[positions]: only_simple | only_complex | no_filter filter[chain_ids]: comma-separated chain IDs (e.g., ethereum,polygon) filter[position_types]: wallet, deposit, staked, loan, locked, reward, investment sort: -value (highest first) or value filter[trash]: only_non_trash (default) ### 3. Transaction History Get recent transactions for wallet {address}, filter for trades only. Endpoint: GET /v1/wallets/{address}/transactions/ filter[operation_types]: trade, send, receive, deposit, withdraw, mint, burn, claim, approve, etc. filter[chain_ids]: filter by chain filter[min_mined_at] / filter[max_mined_at]: timestamp in milliseconds page[size]: max 100 ### 4. Profit & Loss (PnL) Get PnL for wallet {address}. Show realized gain, unrealized gain, fees, and net invested. Endpoint: GET /v1/wallets/{address}/pnl Returns: realized_gain, unrealized_gain, total_fee, net_invested, received_external, sent_external Uses FIFO method filter[chain_ids], filter[fungible_ids]: narrow scope ### 5. Wallet Balance Chart Get the balance chart for wallet {address} over the past month. Endpoint: GET /v1/wallets/{address}/charts/{chart_period} chart_period: hour, day, week, month, 3months, 6months, year, 5years, max Returns array of [timestamp, balance] points ### 6. Token Price & Search Search for the fungible asset "ethereum" and return its price and market data. Endpoint: GET /v1/fungibles/ filter[search_query]: text search (e.g., "ethereum", "USDC") sort: -market_data.market_cap, -market_data.price.last, etc. Returns: name, symbol, price, market_cap, circulating_supply, changes (1d/30d/90d/365d) ### 7. Token Price Chart Get the price chart for fungible {fungible_id} over the past week. Endpoint: GET /v1/fungibles/{fungible_id}/charts/{chart_period} Same chart periods as wallet charts Returns [timestamp, price] points ### 8. NFT Positions List all NFT positions for wallet {address}, sorted by floor price descending. Endpoint: GET /v1/wallets/{address}/nft-positions/ sort: -floor_price, floor_price, created_at, -created_at filter[chain_ids]: filter by chain include: nfts, nft_collections, wallet_nft_collections for richer data ### 9. NFT Portfolio Value Endpoint: GET /v1/wallets/{address}/nft-portfolio Returns total NFT portfolio value ### Building Artifacts with Zerion Data When building React/HTML artifacts that display Zerion data: Collect the API key securely via a type="password" input field Never display or log the key in the UI Pass it through the MCP prompt so the inner Claude can authenticate // apiKey comes from a password input, never hardcoded const response = await fetch("https://api.anthropic.com/v1/messages", { method: "POST", headers: { "Content-Type": "application/json" }, body: JSON.stringify({ model: "claude-sonnet-4-20250514", max_tokens: 1000, messages: [ { role: "user", content: \`Use the Zerion API with key "${apiKey}" to get the portfolio overview for wallet ${walletAddress} in USD. Return ONLY a JSON object with: totalValue, dailyChangePercent, dailyChangeAbsolute, topChains (array of {chain, value}), positionBreakdown (wallet, deposited, staked, borrowed, locked).\` } ], mcp_servers: [ { type: "url", url: "https://developers.zerion.io/mcp", name: "zerion-mcp" } ] }) }); ### Processing MCP Responses MCP responses contain multiple content blocks. Extract data by type: const data = await response.json(); // Get tool results (actual Zerion data) const toolResults = data.content .filter(item => item.type === "mcp_tool_result") .map(item => item.content?.[0]?.text || "") .join("\\n"); // Get Claude's text analysis const textResponses = data.content .filter(item => item.type === "text") .map(item => item.text) .join("\\n"); ### Key Notes Address formats: Supports EVM addresses (0x...) and Solana addresses. ENS names may need resolution first. Solana limitations: No protocol positions or NFT transactions for Solana addresses. Currency options: usd, eth, btc, eur, krw, rub, gbp, aud, cad, inr, jpy, nzd, try, zar, cny, chf Pagination: Use links.next from responses for pagination; never construct page[after] manually. Rate limits: API returns 429 on throttling. Implement retry with backoff in artifacts. Treat IDs as opaque strings: Never assume format of IDs; they may change. DeFi positions: Use filter[positions]=no_filter to include protocol positions alongside wallet positions. LP grouping: Liquidity pool positions share a group_id attribute — group by it to display pools correctly. ### Detailed Endpoint Reference For full parameter details, response schemas, and edge cases: Wallet endpoints: See references/wallet-endpoints.md Fungible & NFT endpoints: See references/fungible-nft-endpoints.md ## Trust - Source: tencent - Verification: Indexed source record - Publisher: vshamanov - Version: 0.1.0 ## Source health - Status: healthy - Item download looks usable. - Yavira can redirect you to the upstream package for this item. - Health scope: item - Reason: direct_download_ok - Checked at: 2026-05-11T12:20:07.042Z - Expires at: 2026-05-18T12:20:07.042Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/zerion-api-skill-2) - [Send to Agent page](https://openagent3.xyz/skills/zerion-api-skill-2/agent) - [JSON manifest](https://openagent3.xyz/skills/zerion-api-skill-2/agent.json) - [Markdown brief](https://openagent3.xyz/skills/zerion-api-skill-2/agent.md) - [Download page](https://openagent3.xyz/downloads/zerion-api-skill-2)
