What is Assymetrix?

The developer portal is an available product with Free, Developer and Pro tiers. Its broad archive description does not override endpoint-specific history windows: general history, snapshots and historical books have separate entitlements. Confirm the intended candle interval and book window before choosing a plan.

The main platform preview presents a terminal, alerts and copying behind a waitlist. That presentation is distinct from the API and does not establish current copy-trading access. Likewise, advertised WebSocket delivery should be checked against the actual subscription.

Who it is for

Developers replacing multiple venue adapters.
Researchers needing history and trades.

Our take on Assymetrix

Canonical schemas, freshness and published tiers give developers a clear starting point. Endpoint coverage and streaming access still need task-specific testing.
