Ingest server-side
Connect WebSocket from your backend with symbol and premium filters so browser clients never hold the master key.

Options Flow API for Fintech Apps
Ship customer-facing options flow widgets and internal alert inboxes without operating OPRA infrastructure — filter on the server, enrich on the print, fan out from your backend.
Who this is for: fintech product teams layering options flow into dashboards (not black-box retail signal apps). You own UX and entitlements; OptionData supplies the licensed tape (~10M trades/day) and ~50ms US HTTP surfaces for companion APIs.
Productize the tape safely
Keep OPRA credentials and full prints on the server; expose only the UX your customers are entitled to see.
Shape the UX payload
Map 30+ fields into customer-safe DTOs — hide raw vendor fields, rate-limit, and apply per-plan symbol caps.
Add chain context cards
On click-through, POST option-chain REST for IV, OI, and Greeks around the alert strike.
Power-user SQL exports
Optional historical SQL for pro tiers without standing up your own multi-billion-row options warehouse.
Fintech constraints this page targets
- No end-user OPRA agreements when you qualify under OptionData terms
- Server-side filters reduce egress and client complexity
- Same key as chain/SQL simplifies entitlement checks
- Pro list $599/mo (first-year promo $299 with coupon) for all three APIs
- 14-day free trial to prototype widgets before launch
- Pair with the general fintech API guide for pricing narrative
Example: backend fan-out pattern
// Backend service: fan-in filtered flow to customer dashboards
const ws = new WebSocket(
`wss://ws.optiondata.io?token=${process.env.OPTIONDATA_KEY}&symbols=${watchlist.join(',')}&min_premium=25000`
);
ws.onmessage = (e) => {
const trade = JSON.parse(e.data);
pubsub.publish(`flow:${trade.symbol}`, sanitizeForClient(trade));

Options flow for fintech FAQ
Can I expose OptionData WebSocket URLs directly to browsers?
Prefer a backend fan-out so API keys and full OPRA-grade prints stay server-side. Expose only sanitized events your product policy allows.
How is this different from the general fintech page?
This page layers the options-flow use case onto fintech product constraints (keys, fan-out, UX payloads). The fintech hub covers all three APIs at the platform level.
Do customers get historical SQL too?
Your subscription includes historical SQL and chains under the same key. You decide which surfaces each customer tier can call through your app.
What latency should product teams expect?
Live trades stream over WebSocket during market hours; companion HTTP APIs typically respond around ~50ms in the US depending on network path.
