/install polymarket-api
Description
Query Polymarket prediction markets. Use for questions about prediction markets, betting odds, market prices, event probabilities, or when user asks about Polymarket data.
Usage Guidance
Install only if you are comfortable with the agent making read-only calls to Polymarket's public API for market data. For tighter control, invoke it only for Polymarket-specific questions or market slugs.
Capability Analysis
Type: OpenClaw Skill
Name: polymarket-api
Version: 1.0.0
The skill bundle is benign. The `SKILL.md` provides clear instructions for using the Polymarket API and does not contain any prompt injection attempts. The `polymarket.py` script uses standard Python libraries (`urllib.request`, `json`) to fetch data from the legitimate `gamma-api.polymarket.com` endpoint. There is no evidence of data exfiltration, malicious execution, persistence mechanisms, or obfuscation. The script's behavior is entirely consistent with its stated purpose of querying public prediction market data.
Capability Assessment
Credentials
Network access is limited in code to HTTPS requests against gamma-api.polymarket.com endpoints for markets and events, with no authentication required.
Install Mechanism
No installer, package dependency, hook, or setup-time mutation is present; the skill documents running a local Python script.
Instruction Scope
The trigger description is somewhat broad for general prediction-market, betting-odds, price, or probability questions, so it may be invoked when the user did not explicitly ask for Polymarket.
Persistence & Privilege
No persistence, background worker, credential access, local file writes, privilege escalation, or system modification behavior was found.
Purpose & Capability
The stated purpose is querying Polymarket prediction markets, and the artifact implements that with top market, search, slug, event, and JSON output modes.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install polymarket-api - After installation, invoke the skill by name or use
/polymarket-api - Provide required inputs per the skill's parameter spec and get structured output
