Why a CLI?

GUIs are great for browsing. CLIs are better for systematic trading. The SimpleFunctions CLI gives you:

Speed: Type a command, get results instantly. No clicking through menus.
Scriptability: Chain commands, pipe output, build workflows
Agent integration: The CLI is the primary interface for the agent system
Keyboard-only: Never leave your terminal

Core Commands

sf scan — Scan markets with filters (category, probability range, venue)
sf edges — Find edge opportunities based on active theses
sf depth — View live orderbook for a specific market
sf market — Get detailed info on a single market
sf thesis create — Start building a new thesis
sf thesis evaluate — Trigger evaluation with new signals
sf strategies — View and manage trading strategies
sf heartbeat status — Check the monitoring engine
sf what-if — Run scenario analysis

Interactive Mode

The CLI supports an interactive chat mode where you converse with the agent:

sf chat

This opens an interactive session where you can discuss theses, ask questions about markets, and instruct the agent to take actions — all in natural language.

Example

# Scan for high-edge economic markets
sf scan --category economics --min-edge 5

# View orderbook depth
sf depth KXRECSSNBER-26

sf thesis create "Oil prices will exceed $120 by mid-2026"

# Check your portfolio
sf portfolio

# Run a what-if scenario
sf what-if --node n1.1 --prob 0.80

# Start the heartbeat monitor
sf heartbeat start --interval 30m

Related Terms

Edge

Edge is the difference between the market price of a prediction market contract and your estimated true probability. Positive edge means you believe the contract is mispriced in your favor.

Thesis

A thesis is a structured investment argument that combines a directional view, a causal model of why the view is correct, and specific market positions that express the view. In SimpleFunctions, a thesis is the core unit of analysis.

MCP Server

An MCP (Model Context Protocol) server exposes SimpleFunctions' prediction market data and analysis tools as structured endpoints that AI agents (like Claude, GPT, or custom agents) can call directly.

API Key

An API key is a secret token that authenticates your requests to SimpleFunctions and to prediction market venues (Kalshi, Polymarket). Each key has permissions and rate limits.
