Every market.
One pipeline.

Artery API is a unified infrastructure layer that aggregates Polymarket, Kalshi, Hyperliquid (Perp / HIP-3 / HIP-4) and the HyperEVM DEX into a single API surface — REST + WebSocket, native shapes preserved.

Native passthrough
Each provider returns its own raw shape inside { native, meta }. No information loss.
Unified streaming
One WebSocket multiplexes Polymarket, Kalshi, and Hyperliquid feeds — no per-venue plumbing.
Non-custodial
Artery never holds withdrawal-capable keys. Agent-trading + KMS envelope encryption.
Note

Artery ships native passthrough today: each provider returns its own raw shape. A unified normalized layer with explicit divergence annotations is on the roadmap.

Why Artery?

One API, four platforms

Skip 6 months of platform-specific integration work.

Non-custodial

Artery never holds your withdrawal-capable keys.

HIP-4 from day one

First aggregator to support Hyperliquid's binary outcome markets.

Native + normalized

Build on raw shapes today; opt-in to unified semantics when they ship.
