Reference and Market Data

Reference and market data endpoints provide public, unauthenticated access to instrument metadata, real-time market data, and historical pricing information. These endpoints form the foundation for price discovery, order book analysis, and trading decision workflows.

Core Data Types

Instrument Reference Data

Use public/get-instruments to retrieve the full catalog of tradable instruments. Each instrument includes:

  • Contract specifications (tick size, quantity decimals, leverage limits)
  • Product classification (perpetual swap, future, option)
  • Trading status and expiry information
  • Underlying index reference

This endpoint should be called on application startup and periodically refreshed to detect new listings or contract expirations.

Real-Time Market Data

EndpointUse CaseUpdate Frequency
public/get-bookOrder book depth (bids/asks)Snapshot on request (up to 50 levels)
public/get-tickers24h summary (high, low, volume, open interest)Updated per trade
public/get-tradesRecent trade historyLast 150 trades (7-day max window)

For low-latency applications, use WebSocket subscriptions instead:

  • book.{instrument_name}.{depth} - Order book updates (10 or 50 levels)
  • ticker.{instrument_name} - Real-time ticker updates
  • trade.{instrument_name} - Trade feed

Settlement and Expiry

public/get-expired-settlement-price provides historical settlement prices for expired futures contracts. Use this for post-trade reconciliation and historical PnL calculations.

Rate Limits

Public endpoints share a global rate limit pool. For market data-intensive applications:

  • Use WebSocket subscriptions instead of polling REST endpoints
  • Cache public/get-instruments responses (updates infrequently)
  • Batch ticker requests by omitting instrument_name to get all tickers in one call

Typical Integration Flow

Step 1 — Bootstrap Reference Data

Call public/get-instruments to load the instrument catalog. Store contract specifications locally.

Step 2 — Subscribe to Market Data

For real-time pricing, establish WebSocket connections and subscribe to:

  • book.{instrument_name}.10 - top 10 order book levels
  • ticker.{instrument_name} - 24h summary stats
  • trade.{instrument_name} - trade feed

Step 3 — Polling Fallback

If WebSocket connections are unavailable, poll public/get-tickers and public/get-book at reasonable intervals (e.g., 1-5 seconds).
