What you’ll need
You don't need to be a developer to set up this integration. Follow this simple guide to get started:
- A Relevance AI account
- A Twelve Data API key with access to the endpoints you plan to use
- Authorization (you'll connect securely using API keys—no sensitive info stored manually)
Security & Reliability
The integration uses secure OAuth authentication, ensuring only authorized workflows access your Twelve Data market information. Relevance AI handles API operations (like GET, POST, PUT, DELETE) in the background—so you don't have to worry about rate limits, data formatting, or authentication tokens.
Built-in validation and type conversion ensure your market data workflows run smoothly, even when handling different financial data formats.
No training on your data
Your data remains private and is never utilized for model training purposes.
Security first
We never store anything we don’t need to. The inputs or outputs of your tools are never stored.
