What you get

Intelligence, not just data.

Signal scoring

Every whale trade gets a 0-1 significance score based on trader grade, size, timing, and market context.

Strategy detection

ML classifies each trader — arbitrageur, momentum, market maker, directional. With confidence scores.

Insider radar

Coordinated wallets, pre-resolution accumulation, suspicious timing. Unique to 0xinsider.

Cursor pagination

Composite timestamp + ID cursors. No skipped records on batch fills. Built for agents that poll.
