The short answer
For real-time options data in 2026, Tradier is the cheapest path (real-time chains with Greeks and IV free to account holders), Alpaca Algo Trader Plus ($99/mo) bundles options for Alpaca traders, Polygon.io sells a dedicated options tier, Databento serves tick-level OPRA usage-based, and Cboe LiveVol ($380/mo) is the institutional option.
For real-time options data in 2026, the pick splits by how serious your options strategy is. Tradier is the cheapest real-time entry: a Tradier Brokerage account holder gets real-time options chains with Greeks and IV through the API at no separate data fee. Alpaca Algo Trader Plus ($99/mo) bundles real-time options into a broker-data plan if you also trade on Alpaca. Polygon.io sells a dedicated options data tier separate from its stocks plan. Databento OPRA is the choice for tick-level options at scale, billed by data volume. Cboe LiveVol is the institutional-grade analytics platform at $380/mo. Model the broker-bundled options route in the Broker API Comparator and the standalone-feed route in the Data-Vendor TCO Calculator.
What "real-time options data" actually requires
Options data is harder than equities data on three counts, and a vendor that nails equities can still be wrong for options:
- OPRA volume. The Options Price Reporting Authority feed carries every quote across every US options exchange, and the message rate dwarfs the equity tape. A vendor either pays for the full OPRA feed or serves a delayed or sampled subset.
- Greeks and implied volatility. Raw quotes are not enough for most strategies; you need the chain decorated with Greeks and IV. Some vendors compute these (often via ORATS or an in-house model), some do not.
- Chain-shaped polling. Options strategies poll whole chains, not single symbols, so the rate limit that matters is whether you can pull a full expiration ladder inside your loop without throttling.
This roundup ranks the vendors on published pricing and documented capability only. No latency benchmark is asserted; "real-time" reflects each vendor's own documentation as cited.
The headline table
All figures are vendor list prices and documented capabilities, verified 2026-05-25 on the pages in Sources.
| Vendor | Real-time options entry | Monthly | Greeks / IV | Tick-level | Notes |
|---|---|---|---|---|---|
| Tradier | Account-holder API | $0 to account holders | yes (via ORATS) | no | Real-time chains; options-first broker |
| Alpaca | Algo Trader Plus | $99 | yes (chains) | yes (tick history) | Bundled with SIP equities feed |
| Polygon.io | Options data tier | separate paid tier | yes (Greeks + IV) | yes | Sold apart from the stocks plan |
| Databento | OPRA, usage-based | from $0 pay-as-you-go | depends on schema | yes (full OPRA) | Billed per GB; $199/mo Standard plan |
| Cboe LiveVol | LiveVol Pro / APIs | $380 | yes (full analytics) | yes (OPRA) | Institutional-grade analytics platform |
Verify each on the vendor page before committing; options data terms change more often than equities terms.
Who wins for which profile
Profile: retail options trader who wants real-time chains for the lowest cost
Tradier. A Tradier Brokerage account holder gets real-time options chains decorated with Greeks and IV through the API with no separate market-data fee, plus WebSocket streaming. This is the cheapest real-time-options path for someone already trading the account. The trade-off is the trading rate cap of 60 requests/minute; for chain-heavy polling, mind that limit. See Tradier vs Tastytrade API for the options-broker head-to-head.
Profile: equities-primary agent that occasionally needs options
Alpaca Algo Trader Plus ($99/mo). If you already run on Alpaca, the $99 plan that buys the full SIP equity tape also includes real-time options chains, so you avoid a second vendor. Alpaca's options surface is newer and trails Tradier on complex multi-leg depth, but for occasional options on top of an equities strategy it is the path of least resistance. Compare in Alpaca vs Tradier API 2026.
Profile: dedicated options data without a broker tie
Polygon.io (now Massive) options data tier. Polygon sells options data as a product distinct from its stocks plan, with Greeks and IV on the higher tier. Use it when you want a pure data vendor not coupled to where you execute. See Polygon.io Options Data Pricing 2026 for the tier breakdown.
Profile: tick-level OPRA at scale
Databento OPRA. Databento serves the full OPRA feed under usage-based pricing (pay per GB, billed on uncompressed binary size), with a $199/mo Standard subscription and $125 in free credits for new signups for historical pulls. This is the realistic route to tick-level options at retail scale, but OPRA volume makes the metered bill move fast; model it before you commit. See Databento vs Polygon.io 2026.
Profile: institutional-grade options analytics
Cboe LiveVol at $380/mo for LiveVol Pro, which bundles the analytics platform, OPRA-sourced data, and Excel RTD functions. This is the step into institutional tooling; for a solo operator it is usually more than the job needs.
Gotchas
- "Real-time" can mean account-holder-only. Tradier's real-time data is tied to holding a brokerage account; the sandbox serves 15-minute-delayed data. Build against production, not sandbox, when you need live chains.
- Greeks source matters. Tradier's Greeks and IV come via ORATS; if your strategy is sensitive to the IV model, confirm the methodology rather than assuming a vendor's numbers match your own.
- OPRA pass-through fees. Exchange data fees can sit on top of a vendor's API fee for professional use. The Data-Vendor TCO for EU Retail covers how OPRA pass-through and record-keeping enter the true bill.
- Chain polling vs rate limits. A 60/min trading cap (Tradier) is fine for execution but tight if you also poll full chains on the same token; separate your data and trading paths.
Size your route with the tools
Two different decisions, two tools. If options data should ride along with your broker, the Broker API Comparator ranks the brokers on whether they fit an options-required, free-tier-required profile; the verified output block below is computed live from that engine. If you want a standalone data feed, the Data-Vendor TCO Calculator prices the vendors for a live-plus-options scenario.

Frequently asked questions
- What is the best real-time options data API for retail in 2026?
- Tradier is the cheapest real-time entry: a Brokerage account holder gets real-time chains with Greeks and IV (via ORATS) through the API at no separate data fee, plus WebSocket streaming (verified 2026-05-25). Alpaca Algo Trader Plus at $99/mo bundles real-time options for Alpaca traders, and Polygon.io sells a dedicated options data tier.
- Which API gives tick-level options data at scale?
- Databento, serving the full OPRA feed under usage-based pricing (per GB on uncompressed binary size), with a $199/mo Standard plan and $125 in free credits for new signups (verified 2026-05-25). OPRA's message volume makes the metered bill move fast, so model your pull volume before committing.
- Is real-time options data free anywhere?
- Effectively only through Tradier, and only as an account-holder benefit rather than a public free tier. Even there the sandbox serves 15-minute-delayed data, so build against production for live chains. Otherwise real-time options access needs a brokerage account, a paid plan, or usage-based billing.
