FYN Finance Agent Skill

The official AI agent skill for FYN — personal finance with bank syncing, receipt AI, and spending intelligence.

What is this?

This is a ClawHub skill package that lets any AI agent (OpenClaw, Clank, or any agent with HTTP tools) access your personal financial data through FYN.

Your agent can:

  • Query bank transactions and spending patterns
  • Check account balances and net worth
  • Monitor budgets and subscriptions
  • Get daily briefings, alerts, and financial health scores
  • Ask natural language questions about your finances
  • Search receipts with AI (Pro)
  • Check affordability of purchases (Pro)

Install

clawhub install fyn-finance

Or manually: copy SKILL.md into your agent's skill directory.

Quick Start

  1. Sign up at fyn.fyi (free)
  2. Connect your bank accounts via Plaid
  3. Generate an API key at Settings > Agent Access
  4. Set FYN_API_KEY in your agent's environment
export FYN_API_KEY=fyn_ak_your_key_here
  1. Ask your agent about your finances:

"How much did I spend on groceries this month?" "What's my net worth?" "Am I over budget on anything?"
