Query blockchain wallet data, token prices, and transaction history using the Zerion API via its MCP connector. Use this skill whenever the user asks about: crypto wallet balances, portfolio values, token holdings or positions, DeFi positions (staking, lending, LP), wallet PnL (profit and loss), transaction history, token/fungible asset prices or charts, NFT holdings or NFT portfolio value, or any web3 wallet analytics. Triggers on mentions of wallet addresses (0x...), ENS names, token names/symbols, "portfolio", "positions", "PnL", "transactions", "balance", "holdings", "NFTs", or any crypto/DeFi analytics queries. Also use when building artifacts or dashboards that display wallet or token data.

Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
Query web3 wallet data, token prices, NFTs, and transaction history via the Zerion MCP connector.
Zerion API requires a key for every request. The key is not stored in the MCP connector settings โ the user must provide it each chat session.
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.
Zerion uses HTTP Basic Auth: the API key is the username, password is empty. Authorization: Basic <base64(API_KEY + ":")> Example: key zk_dev_abc123 โ base64 of zk_dev_abc123: โ emtfZGV2X2FiYzEyMzo=
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 โ 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...`;
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)
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)
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
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
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
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)
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
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
Endpoint: GET /v1/wallets/{address}/nft-portfolio Returns total NFT portfolio value
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" } ] }) });
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");
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 โ group by it to display pools correctly.
