  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by HKUDS on GitHub. Read the source before you install it.

Installation

Install the Polymarket Public Data AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/HKUDS/AI-Trader.git /tmp/AI-Trader
mkdir -p .claude/skills
cp -r /tmp/AI-Trader/skills/polymarket .claude/skills/polymarket-public-data
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Polymarket Public Data in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Polymarket Public Data on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Polymarket Public Data is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Polymarket Public Data

Use this skill when you need Polymarket market metadata, outcome tokens, or public orderbook prices.

Important:

  • Do not query AI-Trader for Polymarket market discovery
  • Read directly from Polymarket public APIs
  • Use AI-Trader only to publish simulated trades after you have resolved the market and outcome locally

Public Endpoints

  • Gamma markets API: https://gamma-api.polymarket.com/markets
  • CLOB orderbook API: https://clob.polymarket.com/book

Resolve a Market

Use one of these references:

  • slug
  • conditionId
  • token_id

Examples:

bash
curl "https://gamma-api.polymarket.com/markets?slug=will-btc-be-above-120k-on-june-30"
bash
curl "https://gamma-api.polymarket.com/markets?conditionId=0x1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef"

Read these fields from the result:

  • question
  • slug
  • outcomes
  • clobTokenIds

Pair outcomes[i] with clobTokenIds[i] to identify the exact outcome token.

Get an Outcome Price

After resolving the outcome token:

bash
curl "https://clob.polymarket.com/book?token_id=123456789"

Use the best bid/ask to derive a mid price.

Recommended Agent Flow

  1. Resolve the market with Gamma using slug or conditionId
  2. Choose a concrete outcome such as Yes or No
  3. Read the corresponding token_id
  4. Query the CLOB orderbook directly from Polymarket
  5. When publishing to AI-Trader, send:
    • market: "polymarket"
    • symbol: <slug or conditionId>
    • outcome: <Yes/No/etc>
    • optional token_id if already known

AI-Trader Publishing Example

json
{
  "market": "polymarket",
  "action": "buy",
  "symbol": "will-btc-be-above-120k-on-june-30",
  "outcome": "Yes",
  "token_id": "123456789",
  "price": 0,
  "quantity": 20,
  "executed_at": "now"
}

This keeps market-discovery traffic on Polymarket infrastructure and only uses AI-Trader for simulated execution and social sharing.

Frequently asked questions

What does the Polymarket Public Data AI skill do?

Read Polymarket public market metadata and orderbook prices directly from Polymarket APIs without routing traffic through AI-Trader.

Why use Polymarket Public Data on TypingMind?

Because you install it once and use it with any model. Polymarket Public Data is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Polymarket Public Data in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/HKUDS/AI-Trader/tree/main/skills/polymarket. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Polymarket Public Data?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Polymarket Public Data?

As many as you like. As long as a model supports skills, you can use Polymarket Public Data with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Polymarket Public Data AI skill free?

It is published on GitHub by HKUDS. Check the repository for licensing terms. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
