Fintool — Financial Trading Skill

What it does

Fintool exposes a suite of CLI binaries for market intelligence (quotes, news, SEC filings), exchange-specific trading (Hyperliquid, Binance, Coinbase, OKX), prediction market access (Polymarket), and historical backtesting with forward PnL. It returns structured JSON and includes workflows for quoting, trading, depositing/withdrawing, portfolio checks, and backtests.

When to use it

Use when the user asks for price quotes, news, trading actions (buy/sell/perp), deposits/withdrawals, portfolio overviews, or historical backtests. Also useful for automating trades where JSON-mode CLIs are acceptable and credentials are managed securely.

What's included

• Scripts: multiple binaries and scripts present under repo scripts/ (has_scripts=true)
• References: none declared (has_references=false)
• Instructions: detailed setup checks, JSON command reference for each binary, error handling conventions, workflows for spot/perp trading, portfolio management, deposits, withdrawals, prediction markets, and backtesting.

Compatible agents

Best for automation-capable agents that can run local CLIs or shell commands and parse JSON outputs (agents with shell/exec capabilities, Code-capable LLMs).
