Questions

What counts as a wall?

A resting limit order that is large for that coin's own book and turnover. The detection rules are not published; every event carries its side, size band, distance to the spread and age, so you can apply your own filter on top.

Do I get the raw order book?

No. The API serves events and their measured properties, not order book levels or the trade tape.

How fresh is the data on each plan?

BASIC: 15-minute delay; PRO: 60-second delay; ULTRA: 15-second delay; MEGA: real time.

How far back can I query?

BASIC: last hour only; PRO: 1 day of history; ULTRA: 7 days of history; MEGA: 30 days of history. History is a rolling window counted from now; one request covers at most 24 hours.

Can I resell or republish the data?

No. The licence covers use inside your own application, bot, dashboard or research. Redistributing the data as a feed, an API or a dataset, or re-hosting it as an MCP server, is not allowed. Informational purposes only. Not financial advice.

What is the ref field in every row?

A short code unique to your subscription and the row. It is stable, so you can use it to deduplicate rows you have already stored.
