Platform · Integrations & APIs

APIs and integrations for event-contract platforms.

Three integration surfaces sit alongside each other. FIX for institutional connectivity, REST for back-office and operator integrations, WebSocket for low-latency client streams.

Surfaces

One platform, three integration surfaces.

Member firms typically connect via FIX. Back-office and operator integrations use REST. End-client and partner-built experiences use WebSocket for live data and low-latency interaction. All three surfaces operate against the same trading core and the same audit trail.

FIX 4.4 / 5.0 SP2
Institutional connectivity for order entry, market data, drop copy.
REST API
Back office, operator, and partner integrations with versioned endpoints.
WebSocket streams
Low-latency client streams for market data and order events.
Webhook delivery
Server-to-server event delivery with retry and signing.

Authentication

Institutional and partner authentication.

Authentication uses scoped API keys with HMAC request signing for server-to-server flows and short-lived bearer tokens for user-facing surfaces. Per-key rate limits, IP allow-lists, and scope-based authorisation are enforced uniformly across surfaces.

API keys & HMAC signing
Scoped keys with request signing for server-to-server integrations.
Short-lived bearer tokens
Issued from operator-controlled identity provider for user surfaces.
IP allow-lists & rate limits
Per-key constraints enforced at the gateway with operator visibility.
Scope-based authorisation
Granular scopes per endpoint and per data class.

Reference architectures

Drop-in integration patterns for common operator shapes.

Reference integration architectures cover the operator profiles we work with most often, exchange member-firm onboarding, brokerage front-end integration, operator white-label, and enterprise internal-market hosting. Each comes with reference diagrams, sample code, and recommended operational practice.

Exchange member-firm onboarding
FIX certification path, market data subscription, drop copy hook-up.
Brokerage integration
Reference for unified trading experience across asset classes.
White-label deployment
Operator-branded surfaces with managed AI ops as a service.
Internal market hosting
Enterprise reference for hosted internal forecasting markets.
