Twelve Data is built to handle billions of requests daily. This raises a key question: Do we support unlimited API requests or WebSocket subscriptions?

Under the Custom plan, we can offer API and WebSocket limits exceeding those of the Enterprise 10946 plan. However, please note that "unlimited" limits are not available; instead, the limits can be set to exceptionally large values as needed. Custom plans come with personalized pricing—feel free to reach out for more details.
