The Python SDK requires Python >= 3.8.\n\n### Python\n```bash\npip install pmxt\n```\n\n### Node.js\n```bash\nnpm install pmxtjs\n```\n\n### Running from Source\n```bash\ngit clone https:\u002F\u002Fgithub.com\u002Fpmxt-dev\u002Fpmxt.git\ncd pmxt\nnpm install\nnpm run dev\n```\n\n### MCP (for AI agents)\n```bash\nnpx -y @pmxt\u002Fmcp\n```\nSee [@pmxt\u002Fmcp](https:\u002F\u002Fgithub.com\u002Fpmxt-dev\u002Fpmxt-mcp) for setup with Claude, Cursor, and other MCP-compatible clients.\n\n## Migrating from Dome API\n\nIf you're currently using **Dome API**, pmxt is a drop-in replacement with a unified interface for Polymarket and Kalshi.\n\nCheck out [pmxt as a Dome API alternative](https:\u002F\u002Fpmxt.dev\u002Fdome-api-alternative) for a detailed migration guide, API comparison, and automatic codemod tool (`dome-to-pmxt`) to help you transition your code.\n\n```bash\n# Automatically migrate your codebase\nnpx dome-to-pmxt .\u002Fsrc\n```\n\n## Quickstart\n\nPrediction markets are structured in a hierarchy to group related information.\n\n*   **Event**: The broad topic (e.g., *\"Who will Trump nominate as Fed Chair?\"*)\n*   **Market**: A specific tradeable question (e.g., *\"Will Trump nominate Kevin Warsh as the next Fed Chair?\"*)\n*   **Outcome**: The actual share you buy (e.g., *\"Yes\"* or *\"No\"*)\n\n### Python\n```python\nimport pmxt\n\napi = pmxt.Exchange()\n\n# 1. Search for the broad Event\nevents = api.fetch_events(query='Who will Trump nominate as Fed Chair?')\nfed_event = events[0]\n\n# 2. Find the specific Market within that event\nwarsh = fed_event.markets.match('Kevin Warsh')\n\nprint(f\"Price: {warsh.yes.price}\")\n```\n\n### TypeScript\n\n> **Note:** Named imports do not work in ESM. Use `import pmxt from 'pmxtjs'` (default import), not `import { Polymarket } from 'pmxtjs'`.\n\n```typescript\nimport pmxt from 'pmxtjs';\n\nconst api = new pmxt.Exchange();\n\n\u002F\u002F 1. Search for the broad Event\nconst events = await api.fetchEvents({ query: 'Who will Trump nominate as Fed Chair?' });\nconst fedEvent = events[0];\n\n\u002F\u002F 2.

For detailed credential setup instructions, see the exchange-specific guides: [Polymarket](core\u002Fdocs\u002FSETUP_POLYMARKET.md), [Kalshi](core\u002Fdocs\u002FSETUP_KALSHI.md), [Limitless](core\u002Fdocs\u002FSETUP_LIMITLESS.md).\n\n#### Polymarket\n```python\nexchange = pmxt.Polymarket(\n    private_key=os.getenv('POLYMARKET_PRIVATE_KEY'),\n    proxy_address=os.getenv('POLYMARKET_PROXY_ADDRESS'), # Optional: For proxy trading\n    signature_type='gnosis-safe' # Default\n)\n```\n\n#### Kalshi\n```python\n exchange = pmxt.Kalshi(\n    api_key=os.getenv('KALSHI_API_KEY'),\n    private_key=os.getenv('KALSHI_PRIVATE_KEY') # RSA Private Key\n)\n```\n\n#### Limitless\n```python\nexchange = pmxt.Limitless(\n    api_key=os.getenv('LIMITLESS_API_KEY'),\n    private_key=os.getenv('LIMITLESS_PRIVATE_KEY') # For order signing (EIP-712)\n)\n```\n\n### Trading Example (Python)\n\n```python\nimport pmxt\nimport os\n\n# Initialize with credentials (e.g., Polymarket)\nexchange = pmxt.Polymarket(\n    private_key=os.getenv('POLYMARKET_PRIVATE_KEY'),\n    proxy_address=os.getenv('POLYMARKET_PROXY_ADDRESS')\n)\n\n# 1. Check Balance\nbalance = exchange.fetch_balance()\nprint(f\"Available balance: {balance[0].available}\")\n\n# 2. Fetch markets\nmarkets = exchange.fetch_markets(query='Trump')\n\n# 3. Place an Order (using outcome shorthand)\norder = exchange.create_order(\n    outcome=markets[0].yes,\n    side='buy',\n    type='limit',\n    price=0.33,\n    amount=100\n)\nprint(f\"Order Status: {order.status}\")\n```\n\n## Documentation\n\nSee the [API Reference](https:\u002F\u002Fwww.pmxt.dev\u002Fdocs) for detailed documentation and more examples.\n\n## Examples\n\nCheck out the directory for more use cases:\n\n[TypeScript](https:\u002F\u002Fgithub.com\u002Fpmxt-dev\u002Fpmxt\u002Ftree\u002Fmain\u002Fsdks\u002Ftypescript\u002Fexamples) [Python](https:\u002F\u002Fgithub.com\u002Fpmxt-dev\u002Fpmxt\u002Ftree\u002Fmain\u002Fsdks\u002Fpython\u002Fexamples)\n\n## Sponsors\n\u003Cdiv align=\"center\">\n\u003Ctable>\n  \u003Ctr>\n    \u003Ctd align=\"center\" width=\"300\" valign=\"middle\">\n      \u003Ca href=\"https:\u002F\u002Fnearbase.dev\u002F?utm_source=pmxt&utm_medium=sponsorship\">\n        \u003Cimg src=\"https:\u002F\u002Fnearbase.dev\u002Fnearbase.svg\" alt=\"Nearbase\" height=\"40\"\u002F>\n      \u003C\u002Fa>\n    \u003C\u002Ftd>\n    \u003Ctd align=\"center\" width=\"300\" valign=\"middle\">\n      \u003Ca href=\"https:\u002F\u002Fondb.ai\u002F\">\n        \u003Cimg src=\"https:\u002F\u002Fondb.ai\u002Fimages\u002Flogo-full-white-text.svg\" alt=\"OnDB.ai\" height=\"40\" valign=\"middle\"\u002F>\n        \u003Cb>OnDB.ai\u003C\u002Fb>\n      \u003C\u002Fa>\n    \u003C\u002Ftd>\n  \u003C\u002Ftr>\n\u003C\u002Ftable>\n\u003C\u002Fdiv>\n\n[![Stargazers repo roster for @pmxt-dev\u002Fpmxt](https:\u002F\u002Freporoster.com\u002Fstars\u002Fpmxt-dev\u002Fpmxt)](https:\u002F\u002Fgithub.com\u002Fpmxt-dev\u002Fpmxt\u002Fstargazers)\n","pmxt是一个为预测市场设计的统一API，支持在多个交易所如Polymarket和Kalshi上进行交易。该项目采用TypeScript编写，提供了一致性的接口来访问不同平台的数据，简化了跨平台操作的复杂性，使得开发者能够轻松地获取市场数据、执行交易策略等。它特别适用于需要整合多家预测市场交易所信息的应用场景，例如算法交易、套利机会捕捉等领域。通过使用pmxt，用户可以更加高效地参与到预测市场的活动中去。",2,"2026-06-11 03:51:31","high_star"]
