OKX Market
Overview
The OKX V5 REST API provides comprehensive cryptocurrency market data covering spot, perpetual swaps, delivery futures, options, and more. All market-data endpoints are public and can be called directly without authentication. The data comes from OKX, the world's second-largest cryptocurrency exchange.
Quick Start
- Install a Python runtime (Python 3.9+ recommended) and the required
requests dependency.
pip install requests pandas
- No account registration or token configuration is required. Market-data endpoints are fully open.
- Review the endpoint documentation below and locate the interface you need.
- Use Python code to retrieve data according to the documentation. Example for the spot ticker endpoint:
import requests
import pandas as pd
BASE_URL = "https://www.okx.com/api/v5"
# Get the latest BTC-USDT market quote
resp = requests.get(f"{BASE_URL}/market/ticker", params={"instId": "BTC-USDT"})
data = resp.json()["data"][0]
print(f"BTC last price: {data['last']} 24h change: {float(data['last'])/float(data['open24h'])*100-100:.2f}%")

Link convention: every link to references/ in this document is written relative to this document (for example references/...) — the form GitHub resolves when someone opens the file in a browser. The read_file tool resolves the same string against the skill that owns it, so the agent and a human reader reach one file. When adding new skill docs, always use the relative form, and keep reference paths unique across skills: a path two skills both carry is reported as ambiguous rather than guessed.
