What's new in October 2026
October was about trust, and about the parts of Twelve Data you use before you call the API: an independent SOC 2 Type 2 attestation, a redesigned pricing page, and documentation that opens faster and is easier to hand to an agent.
See what is included in each plan.
SOC 2 Type 2
On 1 October 2026 we received a SOC 2 Type 2 attestation. An independent auditor has examined how we protect customer data over a period of time.
A new pricing page
Pricing and business pricing have been redesigned. Plans are easier to compare, add-ons are laid out more clearly, and switching between monthly and annual billing now keeps the price on checkout in line with the switch.
Documentation
The API documentation is now split across pages, so it opens faster and you can go straight to the section you need from twelvedata.com/docs. You can also copy a page for an LLM, or open it in ChatGPT and other tools.
The docs now state clearly that looking up an instrument by ISIN or CUSIP is available on all plans. Returning those values in responses still requires the relevant data add-on.
AI agents
Authentication for agents is documented at auth.md. The hosted MCP server signs in through our own authorisation server. Connecting via ChatGPT no longer shows the wrong requesting party on the consent screen. The public MCP server on GitHub, and its listing on the MCP Registry, now use the name Twelve Data and an up-to-date description.
