Why
Your bot is only as good as the context on the trade.
Anyone can see the print. The edge is knowing who placed it and whether it's worth reacting to.

Noise

What you get

Every trade comes with context.

Compact responses, rich metadata. Built for bots that rank, filter, and act on the data — not dashboards.

Dense signal, not another event firehose.

Signal

0–1 signal score

Every whale trade comes with a score that weighs trader grade, size, timing, and market context. Sort by it, filter by it, alert on it.

  • grade-aware
  • size-aware
  • timing-aware
  • market context
Quality

Trader grades

S–F from win rate, volume, edge consistency, and 40+ quant metrics. Recomputed daily.

  • S–F scale
  • 40+ metrics
  • edge consistency
  • daily refresh
Strategy

Strategy detection

ML tags each trader as arbitrageur, momentum, market maker, or directional — with a confidence score.

  • ML classification
  • confidence
  • arb / momentum
  • market maker
Risk

Insider radar

Coordinated wallets, pre-resolution accumulation, and suspicious timing patterns. Not available anywhere else.

  • wallet clusters
  • timing flags
  • pre-resolution
  • pattern alerts
Delivery

Safe cursor pagination

Composite timestamp + ID cursor so polling clients never skip rows during high activity.

  • timestamp + ID
  • no skipped rows
  • batch-safe
  • agent polling
Control

Pay for depth only when you want it

Responses stay lean. Add `expand[]=strategy` (and friends) when you need heavier context, skip it when you don't.

  • expand[]=strategy
  • depth on demand
  • low-latency default
  • optional
Roadmap
