# Polymarket

The `robomotion polymarket` CLI connects to Polymarket for prediction market data and analytics. It retrieves market listings, event details, current pricing/probabilities, orderbook depth, positions, trades, and spread analytics.

## When to use
- Browse prediction markets and get current pricing/probabilities
- View orderbook depth and market spread analytics
- Track positions and trade history
- Search for events and market outcomes

## Prerequisites
- `robomotion` CLI installed
- Package installed: `robomotion install polymarket`
- Polymarket API access configured via Robomotion vault

## IMPORTANT: Session Mode Required for Multi-Step Operations
Each CLI command runs as a **separate process** — connection IDs from `connect` do NOT persist across calls.
You MUST use `--session` on `connect` and pass `--session-id` to all subsequent commands.

## Workflow
1. Install (once): `robomotion install polymarket`
2. Connect with session:
   ```
   robomotion polymarket polymarket_connect --session --output json
   # → {"outClientId":"<client-id>","session_id":"<session-id>"}
   ```
3. Use the returned `client-id` and `session-id` in all subsequent commands:
   ```
   robomotion polymarket polymarket_get_markets --client-id "<client-id>" --session-id "<session-id>" --output json
   ```
4. Disconnect when done:
   ```
   robomotion polymarket polymarket_disconnect --client-id "<client-id>" --session-id "<session-id>" --output json
   ```

**Always** append `--output json` to get structured JSON results.
