/install openclaw-zapper-api
Description
Query DeFi portfolios, token holdings, NFTs, transactions, and prices via Zapper API. Supports 50+ chains. Use when user asks about wallet balances, DeFi positions, NFT collections, token prices, or transaction history.
Usage Guidance
This skill will read an optional config at ~/.config/zapper/addresses.json (or use ZAPPER_API_KEY from your environment) and send GraphQL queries to https://public.zapper.xyz. Before installing: ensure you trust Zapper and are comfortable providing an API key; consider using a dedicated key with limited scope; avoid placing other unrelated secrets in the config file; review the included scripts/zapper.py if you want to verify exactly what data is sent. The skill does not request unrelated credentials or perform unexpected file access.

Description: OpenClaw Agent Skill
Suspicious High-Entropy/Eval files: 1
The OpenClaw Zapper API skill bundle is benign. It provides a CLI interface to query the Zapper GraphQL API for DeFi data. The `scripts/zapper.py` script correctly retrieves the `ZAPPER_API_KEY` from environment variables or a user-specific config file (`~/.config/zapper/addresses.json`) and uses it to authenticate requests to the legitimate `https://public.zapper.xyz/graphql` endpoint. There is no evidence of data exfiltration beyond the API key to the intended service, no malicious execution, persistence mechanisms, or prompt injection attempts in `SKILL.md`.
Capability Assessment
Purpose & Capability
Name/description (Zapper API queries) match the actual behavior: a Python CLI that sends GraphQL requests to public.zapper.xyz. Required binary (python3) and primaryEnv (ZAPPER_API_KEY) are appropriate for this purpose.
Instruction Scope
SKILL.md confines operations to querying the Zapper API, optional local config (~/.config/zapper/addresses.json), and environment variable for the API key. It does not instruct reading unrelated system files or sending data to unexpected endpoints.
Install Mechanism
No external install/download steps are specified (instruction-only skill with included Python script). All network I/O is the expected GraphQL API call to public.zapper.xyz; there are no arbitrary external downloads or extract steps.
Credentials
Only the ZAPPER_API_KEY credential (and optionally a local config file containing the same key and wallet addresses) is requested. This is proportionate to the stated functionality and no unrelated secrets are required.
Persistence & Privilege
The skill is not always-enabled, does not modify other skills or system-wide settings, and does not request elevated or persistent privileges beyond reading its own config file and performing network requests.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install openclaw-zapper-api - After installation, invoke the skill by name or use
/openclaw-zapper-api - Provide required inputs per the skill's parameter spec and get structured output
