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}%")

Parameter Format Reference

• Instrument format (instId):
  • Spot: BTC-USDT, ETH-USDT

• Timestamp: millisecond Unix timestamp (for example 1773763200000)
• Response format: JSON. code=0 indicates success, and data is returned in the data field

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.
