/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 and event data. Expect network requests to Polymarket when it runs, avoid putting private information into search terms, and consider narrowing the trigger wording or adding explicit network permission metadata if your environment requires strict 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 bounded read-only queries for markets, events, searches, slugs, and JSON output.
Instruction Scope
The activation text includes somewhat broad terms like market prices and event probabilities, which could be narrowed, but the surrounding description clearly ties the skill to Polymarket and prediction-market data.
Install Mechanism
The artifact contains a markdown skill file and one Python script using only standard-library modules; there are no package installs, shell installers, or setup-time side effects.
Credentials
Outbound network access to gamma-api.polymarket.com is necessary for the skill and disclosed in the documentation; user search strings may be sent to that API when the skill is used.
Persistence & Privilege
No evidence was found of background execution, persistence, privilege escalation, local file writes, credential handling, account access, or local data indexing.
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
