Fee schedules are scraped automatically every day. Changes are tracked and visible on the Fee Changes page. For the most current rates, always verify directly with the exchange.

All fee data is sourced from publicly available exchange fee schedules and SEC regulatory filings (SR- filings). We do not use proprietary or licensed data feeds.

We make every effort to parse and present fee schedules accurately, but exchange documents can be complex and change frequently. This tool is for informational purposes — always confirm rates directly with the exchange before making business decisions.

Fee Lab is an AI-assisted query interface that lets you ask questions about exchange fee data in plain English. It is available to all registered users at no charge.

Yes. Registered users can generate an API key from the Fee Lab section to query our data programmatically or connect via an MCP-compatible client such as Claude Desktop.

Please email us with the exchange name, fee type, and what you believe is incorrect. We investigate and correct data errors promptly.
