Zerion Api

**Judgement:** A strong, focused skill for on-chain analytics over Zerion’s API, well-suited for research, monitoring, and data-driven crypto workflows, assuming the user can provide and manage a Zerion API key. **What it does well** - Exposes a wide range of *interpreted* wallet data: portfolios, PnL, DeFi positions, NFTs, gas prices, and token prices. - Supports many EVM chains plus Solana, enabling coherent multi-chain analysis from a single tool. - Good promptability: the description lists concrete example queries and workflows (portfolio breakdowns, DeFi protocol usage, cross-chain comparisons), which LLMs can mirror. - Straightforward MCP configuration (single HTTP endpoint with Bearer token header). **Key risks & limitations** - **API key dependency:** Skill is unusable without a valid Zerion API key; rate limits or quota exhaustion can silently degrade UX. - **Privacy / deanonymization risk:** Designed for wallet research; combining this with off-chain identifiers can increase re-identification risk of individuals. - **Financial interpretation risk:** Outputs may be mistaken for investment advice; PnL and portfolio views should be treated as informational, not prescriptive. - **Third-party dependency:** Fully depends on Zerion’s infrastructure and API stability; outages or schema changes would impact reliability. **Recommended scenarios** - Building assistant workflows for **wallet research**, **customer / competitor on-chain analysis**, or **DeFi usage profiling**. - Creating dashboards or reports that need **real-time portfolio, PnL, gas, and token price data** across multiple chains. - Investigating **NFT portfolios** and **multi-chain activity patterns** (e.g., comparing Ethereum vs Solana usage). - Internal analytics tools where a team already has (or can provision) a Zerion API key and accepts third-party infra dependency.
