/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 this if you want an agent to fetch public Polymarket market data. Expect outbound requests to Polymarket whenever the skill is used, avoid putting private information in search terms, and prefer a narrower trigger description or declared network permission if you require stricter governance.
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
Purpose & Capability
The stated purpose is querying Polymarket prediction market data, and the script implements read-only lookups for markets, searches, slugs, events, and JSON output from gamma-api.polymarket.com.
Instruction Scope
The routing description includes broad terms like betting odds and event probabilities, which could trigger the skill for loosely related queries, but the actual capability remains limited to public Polymarket data retrieval.
Install Mechanism
There is no package install or dependency setup beyond Python standard-library use, and the included file hashes match metadata; provenance is limited because no upstream source or homepage is supplied.
Credentials
Outbound network access is necessary for the skill and is disclosed in SKILL.md, scoped in code to Polymarket's public Gamma API, and does not require authentication or local sensitive data.
Persistence & Privilege
No evidence of persistence, background execution, privilege escalation, credential handling, file writes, or local state storage was found.
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
