Worst data company
Worst data company - keep away. Lacks basic data as VIX and refuses refunds. Worst customer service.

Hi,
Thank you for taking the time to share your feedback—we're genuinely sorry to hear about your disappointment with your experience.
To provide some context for other readers: Our data coverage, including the fact that certain index symbols like VIX are not supported, is clearly and publicly documented on our Markets page and throughout our API documentation. These limitations are listed before any signup or purchase to help users make informed decisions. We also offer a free Basic plan specifically so people can test coverage and features upfront without commitment.
Regarding refunds, our policy states that all subscriptions are final and non-refundable once processed—this is transparently available on our pricing and refunds pages prior to payment.
We take all feedback seriously and are constantly working to improve our service and documentation. If there's anything specific we can clarify or assist with (technical questions, data usage, etc.), please feel free to reach out directly via support@twelvedata.com—we're here to help.
We appreciate your input and wish you the best moving forward.
Kind regards,
The Twelve Data Team

Great but can be better
it‘s really good，but it‘s not cheap if want to use the full websocket. Hope in the future, the user can pay for the single access like wti future for who only want to get, or can choose to subscribe certain things rather than buy a range of data.

Thank you for the feedback! We're glad you're enjoying the service overall.
We hear you on the pricing for full WebSocket access — a pay-as-you-go option or subscriptions for specific symbols/markets is on our roadmap, and we hope to roll it out soon.
Thanks again for the suggestion — it helps us improve! If you need any help in the meantime, just let us know. 🚀

Disappointing customer service
First, everything looked amazing. The documentation is nice and everything went smoothly in the beginning.
Then, I needed a data addon, confirmed with support that this is available and upgraded to a premium plan. Afterwards, I spend 3 weeks (!!) chatting with support because the data was not available.

Hi Karim,
Thank you for taking the time to share your experience — we’re truly sorry to hear that it fell short of expectations.
We appreciate your initial positive feedback, and we’re equally disappointed that the situation with the data add-on caused confusion and frustration. The feature in question was brand-new at the time, and unfortunately, internal communication gaps led to inaccurate guidance about its availability and cost. That was our mistake.
Your feedback has helped us identify and improve the onboarding process for new features and ensure clearer communication moving forward. We understand the importance of your time and trust, and we regret that this was not reflected in your support experience.
If you’re open to it, we’d love the opportunity to make things right. Please feel free to reach out directly to us at support@twelvedata.com referencing this review.
Kind regards,
The Twelve Data Team
Great API and wonderful team.
I use the api in the plan Grow. So I can ask 50 funds a minute. That is a fair price.
Until there was no downside.
The dashboard is a hit. I love it.
The support team responds very quickly, is knowledgeable, and very friendly.
