What it does
Web3 Polymarket is an agent skill from Polymarket/agent-skills. Polymarket integration for prediction market trading on Polygon. Covers authentication (L1 EIP-712, L2 HMAC-SHA256, builder headers), order placement (GTC/GTD/FOK/FAK, batch, post-only, heartbeat), market data (Gamma API, Data API, orderbook, subgraph), WebSocket streaming (market/user/sports channels), CTF operations (split, merge, redeem, negative risk), bridge (deposits, withdrawals, multi-chain), and gasless relayer transactions. Use when building AI agents, autonomous market makers, prediction market UIs, or…
Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files (for example `README.md`, `authentication.md` and `bridge.md`). Compatibility notes: Requires network access to Polymarket APIs (clob.polymarket.com, gamma-api.polymarket.com) and Polygon RPC
It sits in Backend & APIs, covering Realtime and WebSockets, Crypto and DeFi analysis and Capture the flag. It works with Polymarket, Python and TypeScript. The repository describes itself as: Public repository for Polymarket Agent Skills.
When your agent uses it
- Building AI agents
- Autonomous market makers
- Prediction market UIs
- Any application integrating with Polymarket on Polygon
Example prompts
- “/web3-polymarket”
Requirements
- Python 3
- A credential in PRIVATE_KEY
- Compatibility (from SKILL.md): Requires network access to Polymarket APIs (clob.polymarket.com, gamma-api.polymarket.com) and Polygon RPC
What it can do on your machine
Read from SKILL.md and the folder at commit 91ee44a. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript and python).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
clob.polymarket.comgamma-api.polymarket.comdata-api.polymarket.comrelayer-v2.polymarket.combridge.polymarket.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
PRIVATE_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
Requires network access to Polymarket APIs (clob.polymarket.com, gamma-api.polymarket.com) and Polygon RPC
From compatibility in the SKILL.md frontmatter.
Context cost
Web3 Polymarket loads about 2k tokens when it runs. Until then it costs about 148 tokens; SKILL.md has 415 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 415 words (~1,997 tokens).
