FAQ

The APIs, answered.

What does the Intraday Data API give me that the Data API does not?

Granularity. The Data API gives you one clean snapshot per trading day, back to 2007. The Intraday Data API gives you the same families of data (strikes with greeks and smoothed values, implied monies, SMV summaries) sampled every minute of the session, back to August 2020. It is the difference between knowing where volatility closed and watching it move through an earnings print or a CPI release.

How far back does the one-minute history go?

August 2020 for over 5,000 symbols, which is more than 250,000 minutes of market. Option-level OPRA information goes back to January 2022 for 1,270 tickers.

What format do responses come back in?

A minified CSV file, not JSON. One minute of a full options chain is a lot of rows, and CSV keeps the payload small enough to pull at scale and hand straight to a parser or a dataframe.

What is the difference between strikes, monies, and summaries?

Strikes is every contract on the chain for that minute, with greeks and ORATS smoothed values. Implied monies is the fitted surface for each expiration: seed volatilities at 21 call deltas, at-the-money term structure with and without the earnings effect, and weighted market width. SMV summaries is the interpolated view: constant-maturity implied volatilities from 10 to 365 days at four deltas, forward and flat forward volatility, borrow rate, and contango.

How do I get the live intraday endpoints?

Sign the live data agreements, available right after signup. The delayed and historical intraday endpoints work immediately and run 15 minutes behind the market.

What does it cost?

The Live Intraday API is $599 per month and includes 1,000,000 requests plus every data endpoint ORATS publishes. Each plan includes everything in the plans below it, so that covers the delayed and live end-of-day endpoints too. The All-In API at $899 per month adds all four Tools APIs on the same token.

Should I use this API or the bulk one-minute files?

Use the API when you want specific minutes, contracts, or expirations on demand, and when you want live data. Use the one-minute historical file set when you want to hold the whole archive locally for research: that is roughly 50TB delivered over AWS S3, or on physical drives if a download that size is impractical.

Do you cover options on futures?

No. ORATS covers options on US equities, indexes, and ETFs. We do not cover futures options such as ES, GC, or CL.

What are the Tools APIs?

Four REST APIs that run the same engines as the ORATS dashboard's Option Scanner, Options Backtester, Intraday Backtester, and Time and Sales. The data APIs give you options data to compute against. The Tools APIs give you the computed answer: ranked trade candidates, stored backtest results, minute-level backtest reports, and trade prints with greeks on them.

Is there an API for the ORATS backtester and option scanner?

Yes to both, and they are live today as add-ons to any data API plan. The Backtest Finder API searches the 300M+ precomputed backtests behind the Options Backtester and returns full results for any row. The Option Scanner API runs the same scans the dashboard scanner runs. The Intraday Backtester API submits custom 1-minute backtest jobs, and the Time & Sales API serves tick-level trade prints.

How do I authenticate?

With the ORATS token you already have. It covers every data API and Tools API on your subscription. Where it goes differs: the Option Scanner API reads an Authorization header holding the raw token with no Bearer prefix, and the Backtest Finder, Intraday Backtester, and Time & Sales APIs read a token query parameter. Each API's docs say which.

How far back does the Time & Sales API go?

Option prints start September 9, 2022. You query by trade date and narrow from there by contract, time of day, and minimum print size. The live endpoints serve the current session's prints as they occur, and every option print, live or historical, carries delta, gamma, implied volatility, and the underlying stock price from the ORATS one-minute greeks snapshot.

What do the Tools APIs cost?

Each one is a flat monthly add-on to any ORATS data API subscription: $99 for the Option Scanner API, $99 for the Backtest Finder API, $299 for the Intraday Backtester API, and $299 for the Time & Sales API. Take as many as you want on the one subscription, or get all four with the $899 per month All-In API plan.

Do I need a Trading Tools subscription?

No. The Tools APIs attach to a data API plan and bill separately from the $99 per month Trading Tools dashboard subscription. That dashboard subscription is what you want if you would rather click these tools than call them.

Can my AI agent use these?

Yes. It is all plain HTTPS and JSON, so anything that can run curl can call the data APIs and the Tools APIs. The ORATS CLI wraps every data API and Tools API endpoint for Claude Code and Codex if you would rather not write the HTTP calls yourself.
