What Is OPRA Options Data? Licensed U.S. Options Feeds
OPRA (Options Price Reporting Authority) governs consolidated last sale and quote reporting for U.S. exchange-listed options. Professional apps typically need properly licensed OPRA-derived data.
OptionData provides an OPRA-licensed U.S. equity options feed for real-time trades (~10M+/day), with historical SQL and option chains under the same commercial plan. Teams do not need to scrape unlicensed sources.
Why licensing comes up in reviews
For commercial apps, procurement and redistribution rules matter as much as latency.
Match use case to rights
Internal research, customer displays, and redistribution can imply different contractual needs. review your plan terms.
Integrate a vendor API
OptionData delivers trades over WebSocket plus chains/SQL so engineering does not operate exchange connectivity directly.
Operational signals
Pair licensing with reliability metrics teams already track. e.g. 99.9% uptime (30-day) signals and US ~50ms HTTP responses.
What an OPRA-licensed feed means here
- Data originates from the U.S. listed options market data system
- Vendor agreements define display, non-display, and redistribution
- OptionData: real-time trades + historical SQL + chains commercially
- Not a substitute for reading your specific subscription terms
- Fintech apps should keep keys server-side when embedding
- See fintech and flow guides for product patterns
Example: connect to OptionData’s licensed stream
// OptionData exposes OPRA-licensed U.S. equity options trades
// over WebSocket during market hours (plan terms apply).

Is OptionData OPRA licensed?
Yes. OptionData provides an OPRA-licensed U.S. equity options feed under its commercial plans for real-time and related product surfaces.
Can I scrape free delayed pages instead?
Scraping is brittle, often against site terms, and usually unsuitable for professional or redistributed products. Licensed APIs are the durable path.
