Get started

Start free, no card

DepthFeed is in early access. Grab a free Explorer key and start pulling real order-book depth today — upgrade to Quant or Desk when your strategy is ready for the full book.

How early access works

While we finish the self-serve dashboard, keys are issued by hand so we can keep an eye on capacity. It is quick: email hello@depthfeed.com with the venue you care about (Polymarket, Kalshi, or both) and we will send a free Explorer key the same day.

What you get on the free Explorer tier

31-day rolling history of historical order-book depth
Read-only REST API, 1 request per second
BTC markets (latest, capped) — the full bid/ask book, both sides

Ready for all assets, both venues, and whole-day Parquet bulk export? See pricing for the Quant ($29/mo) and Desk ($200/mo) plans, or read the docs first.
