Description
Monitor Polymarket prediction markets for price movements, volume spikes, and new listings. Track specific markets, check order book depth, and surface trend...
README (SKILL.md)
Polymarket Monitor
Track prediction market prices, volume, and liquidity on Polymarket using the Gamma API and CLOB API.
When to Use
Use this skill when the user asks about:
- Trending or popular Polymarket markets
- Current price or probability for a prediction market
- Volume or trading activity on a market
- Order book depth or liquidity for a specific outcome
- New or recently created prediction markets
- Price movements or volume spikes on Polymarket
Key Concepts
- Price = Implied Probability: A contract at $0.65 means 65% implied probability
- Token ID: Each outcome (Yes/No) has a unique token ID used by the CLOB API
- Condition ID: The unique identifier for a market (question) in the Gamma API
- CLOB: Central Limit Order Book — where bids and asks are matched
Operations
1. List Trending Markets
Show the top active markets sorted by 24-hour volume:
curl -s "https://gamma-api.polymarket.com/markets?closed=false&active=true&order=volume24hr&ascending=false&limit=10" \
| jq '[.[] | {
question: .question,
price_yes: (.outcomePrices // "[]" | fromjson | .[0] // "N/A"),
price_no: (.outcomePrices // "[]" | fromjson | .[1] // "N/A"),
volume_24h: ((.volume24hr // 0) | tonumber | round),
total_volume: ((.volumeNum // 0) | tonumber | round),
liquidity: ((.liquidityNum // 0) | tonumber | round),
end_date: .endDate
}]'
## About
Built by [AgentBets](https://agentbets.ai) — full tutorial at [agentbets.ai/guides/openclaw-polymarket-monitor-skill/](https://agentbets.ai/guides/openclaw-polymarket-monitor-skill/).
Part of the [OpenClaw Skills series](https://agentbets.ai/guides/#openclaw-skills) for the [Agent Betting Stack](https://agentbets.ai/guides/agent-betting-stack/).
Usage Guidance
This skill appears coherent and low-risk: it simply issues HTTP requests to Polymarket and parses the JSON with jq. Before installing, consider: 1) provenance — the registry lists no homepage/source repo; if you need stronger assurance, verify the author or prefer a published repo. 2) network/privacy — the agent will make outbound requests to polymarket endpoints (no credentials requested), so sensitive local data is not required but network activity will occur. 3) rate-limiting and reliability — repeated automated polling can trigger API limits; implement sensible throttling if you invoke it frequently. If you want to be extra cautious, run the skill in a controlled environment or test with low-frequency requests first.
Capability Analysis
Type: OpenClaw Skill
Name: agentbets-polymarket-monitor
Version: 1.1.0
The skill provides legitimate functionality for monitoring Polymarket prediction markets using the official Gamma API (gamma-api.polymarket.com). The operations in SKILL.md are transparent, using standard system tools (curl, jq) to fetch and format public market data without any evidence of data exfiltration, malicious execution, or prompt injection.
Capability Assessment
Purpose & Capability
Name/description (Polymarket monitoring) match the runtime instructions: the SKILL.md shows curl calls to Polymarket's Gamma API and parsing with jq. Requested binaries (curl, jq) are exactly what the examples use.
Instruction Scope
Instructions are narrowly scoped to calling the Gamma API and parsing results. The doc references the CLOB API and several operations (order-book depth, new listings) but only provides an example for listing trending markets; this is a functional incompleteness rather than a security concern. The instructions do not read local files, environment secrets, or send data to unexpected endpoints.
Install Mechanism
No install spec and no code files — instruction-only skill. This minimizes disk-write risk and matches the simple curl/jq approach.
Credentials
The skill declares no required environment variables or credentials. That is proportionate to its stated purpose (public API reads).
Persistence & Privilege
always is false (default) and the skill does not request system-wide changes or persistent credentials. Autonomous invocation is allowed (platform default) but not combined with other concerning privileges.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install agentbets-polymarket-monitor - After installation, invoke the skill by name or use
/agentbets-polymarket-monitor - Provide required inputs per the skill's parameter spec and get structured output
