Description
Query crypto wallet portfolios, transactions, DeFi positions, NFTs, token prices, and gas fees across EVM chains and Solana using Zerion's API.
Usage Guidance
Before installing or enabling: 1) Confirm the skill's origin — the registry record shows no homepage/source but README names an author and an npx install path; verify that the package you install comes from the expected repository/author. 2) Be aware an API key is required even though the metadata doesn't list one; make sure you supply a least-privilege, revocable/read-only Zerion API key and understand where MCP configuration stores that key. 3) Inspect any external package (e.g., abishekdharshan/zerion-api) referenced in README before running npx or installing. 4) Verify the skill only calls the documented endpoint (https://developers.zerion.io/mcp) and not other unexpected hosts. 5) If you need stronger assurance, request a provenance check from the publisher (source repo, release tags) or test with a throwaway key and non-sensitive wallet addresses first.

Description: OpenClaw Agent Skill
The skill bundle is benign. It provides instructions and metadata for integrating with the Zerion API to query crypto wallet data. All external URLs point to the official Zerion API documentation and service endpoints (developers.zerion.io, dashboard.zerion.io). The SKILL.md and README.md files clearly outline the skill's purpose, required API key for authentication (to be provided by the user), and setup steps, without any evidence of prompt injection attempts, data exfiltration, malicious execution, persistence mechanisms, or obfuscation.
Capability Assessment
Purpose & Capability
The SKILL.md clearly describes a Zerion MCP API integration (portfolio, tx history, prices, NFTs, etc.), which is coherent with the skill name. HOWEVER the registry metadata lists no required credentials or primaryEnv while the SKILL.md repeatedly states an API key is required and shows how to configure it in MCP settings. Also the registry's source/homepage are missing while README claims an author and an npx install path (abishekdharshan/zerion-api) that doesn't match the registry owner ID — this mismatch should be resolved.
Instruction Scope
The runtime instructions stay within the stated purpose: they describe queries to Zerion's MCP HTTP endpoint (https://developers.zerion.io/mcp) and show example request/config JSON. The SKILL.md does not instruct the agent to read arbitrary local files or unrelated env vars. The only scope caveat: it tells the user to add an API key to the MCP configuration — that configuration is where secrets will be stored and accessed by the skill, so confirm how your platform stores MCP config.
Install Mechanism
This is an instruction-only skill with no install spec and no code files, so nothing is written to disk by an installer here. That reduces technical risk. README's npx install suggestion points to an external package — if you plan to run that, inspect that package separately before installing.
Credentials
The SKILL.md requires an API key (Authorization: Bearer YOUR_API_KEY) to access Zerion's MCP, but the registry metadata lists no required env vars or primary credential. This discrepancy is important: the skill will need a credential to function, but the package metadata doesn't declare it, so automated permission reviews may miss it. Confirm what exact secret(s) the skill needs, where they are stored, and that you only provide a least-privilege, revocable/read-only key.
Persistence & Privilege
The skill does not request always:true and has no install hooks, code, or config-writing steps in the SKILL.md. It only instructs how to add an API key to MCP config. There is no evidence it modifies other skills or system-wide settings.
How to Use
