June 2026 updates
Product Update. AI Assistant Integration, Smarter Currency Conversion & a Faster Docs Experience
We've shipped a batch of improvements across the API, real-time data, and our website and apps. Here's what's new.
New: Twelve Data MCP Server brings market data straight into your AI assistant
You can now connect Claude, ChatGPT, and other MCP-compatible AI assistants directly to Twelve Data. Once connected, you can simply ask your assistant things like "What's the RSI for AAPL?" or "Show me TSLA's latest earnings" and it will pull live data from our API — no code required. There's a hosted option with one-click login (nothing to install) as well as a local option for running the server with your own API key. 📖 Read the MCP Server documentation
Currency & cross-asset conversion fixes
We fixed an issue where conversions between mismatched asset types — for example, a stock priced in a different currency than requested, like AAPL/TRY — could fail or return an error. The time_series/cross endpoint now correctly resolves these mixed-currency conversions.

More predictable API error responses
The API now returns standard HTTP status codes (e.g. 404 for a bad request) for error responses across the board, instead of always returning 200 with the error described in the body. This makes it easier to handle errors programmatically with standard HTTP tooling. (Requests made through RapidAPI are unaffected, to preserve compatibility.)
