US stocks market data

Every Twelve Data subscription plan includes access to real-time US stock market data by default. This data covers the entire universe of listed US equities, including all companies listed on the NYSE, Nasdaq, and every other US exchange.

Pricing data is sourced from venues that do not require additional licensing. These venues collectively represent approximately 5% of total US trading volume, providing a reliable, compliant, and cost-efficient solution for real-time analytics and application development.

You can explore all available US symbols via the Markets page or directly through the Twelve Data API.

The term US trading volume refers to the aggregate share of executed trades across all registered US stock exchanges and alternative trading systems. This includes trading activity from major venues such as NYSE, Nasdaq, Cboe, IEX, and others. The default Twelve Data feed captures roughly 5% of this total market activity, sourced from compliant, low-latency venues that allow redistribution without additional licensing. This coverage ensures accurate pricing and realistic liquidity representation suitable for most analytical, charting, and application use cases.

If you require broader coverage or higher-volume data — for example, consolidated feeds from all major US exchanges — please contact our team to arrange licensed access to full-market data.

All Twelve Data paid plans include access to real-time US stock market data suitable for both personal and commercial use. No additional exchange fees are required to access the default feed. However, some conditions apply depending on your intended use:

If your use case involves external redistribution — such as brokerage, reselling, or providing access to clients — Twelve Data offers Redistribution Rights Add-Ons. These grant permission to redistribute data externally in compliance with Twelve Data policies. Redistribution can apply to both real-time and delayed feeds, across display and non-display scenarios. Our compliance team will assist you in establishing a fully compliant configuration aligned with your business needs.

Twelve Data offers White Label solutions for businesses that wish to deliver market data under their own brand while maintaining regulatory compliance. With this add-on, you can:

White Label solutions are ideal for data vendors, brokers, and enterprise resellers leveraging Twelve Data’s infrastructure as their data backbone.

It does not require additional licensing and covers 100% of total US trading volume, aggregated from every stock exchange, offering a comprehensive daily view of all listed US equities.

OTC (over-the-counter) securities are not included by default in any Twelve Data plan. These instruments trade outside of traditional exchanges and require separate licensing.

If you wish to access OTC Markets data, please contact us to discuss options and pricing.
