Questions, answered.

Do I need to know how to code?

No. Paste one line into Claude or any MCP-capable agent and ask for what you want in plain English. If you do write code, the REST API, WebSocket and Kafka feeds are documented and ready.

Is the data real time?

Yes. Options flow, dark pool prints and Nasdaq equities data arrive in real time on every tier. Basic and Advanced include GEX / Gamma Exposure. Advanced adds WebSocket streaming of option trades and SPX Periscope, plus 1-minute SPX Market Maker Exposure. Starter and Basic do not include WebSockets.

Do I need a credit card to start the trial?

Yes. A valid card is required for an eligible 7-day free trial. Trials are for new API subscribers. You will not be billed during the trial. Monthly Starter renews at $99/month after the trial unless you cancel. Annual Starter has no free trial.

What happens after 7 days?

Your selected plan continues at the price and billing interval shown at checkout unless you cancel during the trial. Monthly Starter continues as API Options Starter at $99/month. If you cancel during the trial, you will not be charged. Annual Starter has no free trial.

How far back does the history go?

Starter includes one year of historical lookback on monthly and annual plans. Basic and Advanced include 2 years. The separate API Trial plan includes 3 months of history; a free trial of a monthly subscription uses that plan's lookback. For anything deeper, or for streaming at scale, talk to us about an enterprise plan.
