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.
Unique context: 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 — so product teams are not stitching unlicensed scrapes.
Why licensing shows up in product reviews
Procurement, compliance, and redistribution rules matter as much as WebSocket latency for commercial apps.
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 “OPRA-licensed feed” means for builders
- 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).
const ws = new WebSocket('wss://ws.optiondata.io?token=YOUR_API_KEY');Product pages that depend on licensed data
OPRA context sits under every flow and fintech page.
OPRA options data FAQ
What does OPRA stand for?
Options Price Reporting Authority — the industry framework for consolidated U.S. options last sale and quote reporting.
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.
Does licensing remove the need for my own compliance review?
No. You should still review OptionData plan terms and any redistribution/display obligations for your product and jurisdictions.
