Clean NBBO bid/ask snapshots for any US option contract, at the interval you choose, by SQL API.
600 requests a minute on your own key and up to 20,000 rows a query — Pro's limits. You create the account on the next screen, then checkout. Sold under our Terms. Already subscribed? Your plan, your price and your access are unchanged — this one is for new customers.
This runs on the no-key endpoint, right now, against the 2026-10-30 session — so you can see the shape of the answer before you pay for the depth. The contract is the most-quoted SPY call in the nearest monthly expiry on that session, picked from the tape rather than typed into this page. Without a key the same call reads the last 5 days of the tape; on this plan it reads all of it.
Loading a live quote…
Start by listing the contracts quoted in that session — no strike to guess at:
curl "https://ai.strasmore.com/v1/demo/options/contracts?underlying=SPY&date=2026-10-30&expiry_from=2026-11-20&expiry_to=2026-11-20&type=C"
A quote counts when it is both sides quoted (bid_size > 0 and ask_size > 0), neither price negative, and ask_price >= bid_price. Columns: contract, bucket_end, bid, ask, bid_size, ask_size, mid, quote_time. Full endpoint reference.
| Limit | No key | Options Quote History |
|---|---|---|
| cache_options_quotes | last 5 days | the whole tape |
| History on everything else | 1 year | full history |
| Rows per query | 500 | 20,000 |
| Requests a minute | per IP, shared | 600 on your key |
Every figure here is read from the same entitlement config the server applies to your queries, not written into this page.
Everything else in the catalogue is included, with no year window: the full table and column catalogue is public, so you can look before you subscribe. Want the trade tapes and the greeks too? Pro is $249/month.

How far back does the options quote tape go? To 2022, and this plan reads all of it — there is no rolling window on it and no year count.
Is this Pro? No, and that is the point. Pro ($249/month) adds the tick trade tapes and the computed greeks. This is the options quote half, on its own, at $79/month.
Does the price go up later? Not on its own. You are billed $79/month for as long as the subscription runs.
Can I cancel? Yes, in the billing portal, any time.
Figures on this page describe what the plan reads. Nothing here is investment advice.
