For developers

Free REST API for Turkish fund data

For AI assistants

Connect Claude or ChatGPT to Turkish fund data

Fonoloji runs a Model Context Protocol (MCP) server. Add it as a connector and ask in your own words: compare funds, look up holdings, read KAP disclosures or check live prices. The assistant picks the right tool itself.

Set up MCP

The setup guide is in Turkish. The MCP quota is separate from the API quota.

Connector URL
https://fonoloji.com/mcp
  • Works with Claude, ChatGPT, Cursor, VS Code and any other MCP client.
  • Included in free membership: 300 tool calls and 75 different funds or stocks per day.
  • Portfolio access is off by default; you choose what to share when you connect.

Data comes from TEFAS (prices, fund size, investors, asset allocation) and KAP (portfolio reports, disclosures, fees). Fonoloji is not an investment firm and nothing on this site is investment advice. The full site is in Turkish.
