OKX Tickers — Free Cryptocurrency Market Data from OKX Exchange (No Key)

TL;DR

OKX provides a public REST API endpoint for market tickers covering spot, margin, futures, perpetual swaps, and options trading. The tickers endpoint returns 24-hour trading statistics including open/high/low/last prices, volume, and price change percentages for every listed instrument. No API key is needed for public market data, making it one of the most accessible exchange APIs for crypto price monitoring.

Frequently Asked Questions

What instrument types are available?: The API supports SPOT (spot trading), SWAP (perpetual swaps), FUTURES (delivery futures), and OPTION (options). Each has its own ticker data structure.
What fields are in each ticker?: Each ticker includes: instId, last, lastSz, askPx, bidPx, open24h, high24h, low24h, vol24h, change24h, and ts (timestamp).
Do I need an API key?: No. The public ticker endpoints are freely accessible without any authentication. Only private endpoints (trading, account info) require keys.
How often is the data updated?: Ticker data is updated in real-time as trades happen on the OKX exchange. The 24-hour rolling stats update with each new trade.
Can I query a single instrument?: Yes. Use the /api/v5/market/ticker (singular) endpoint with an instId parameter like ?instId=BTC-USDT to get data for a single pair.
Is there a rate limit?: OKX imposes rate limits on public endpoints, but they are generous for basic market data polling. Check OKX API documentation for current limits.
