The scanner ranks every route by net spread through the order book, after both legs’ fees, with alerts to Telegram and a trade journal. The first week is free.

Open the scanner

Below are the venues the scanner watches for API3, each against the average of them all, and the perpetual’s premium over spot where one exchange quotes both. The best buy and the best sell are picked among venues in one quote currency.

A gap at the touch is not what you get: the book under it, the fees of both legs and the time to move funds eat into it. The pairings the scanner ranks are measured through the book at a given size and after fees — that is the net spread, and that is what to compare.

The first pairings are shown here as they stand right now; the whole list with filters, alerts and the journal is in the scanner.

FAQ

Why is API3 priced differently on each exchange?

Every exchange is its own market with its own buyers and sellers; prices converge through arbitrage, not by decree, so a gap is always there and never exactly zero.

Is the best spread shown here what I would get?

No — it is the gap at the touch before fees. The scanner measures each pairing through the order book at your size and after both legs’ fees.

How fresh are these numbers?

The page is rendered from the scanner’s own data and refreshed in the browser every couple of seconds, the same freshness the scanner has.

How to read this

The net spread: what you actually get at your size

The spread at the best prices, less the walk through the book, less both venues' fees — worked through on numbers.

Spread impact: how much your size eats of the spread

The share of the spread your deposit eats, the filter on it, and the max safe size.
