Massive Exchange data feed

核心功能是通过REST、WebSocket、Flat Files三种方式，获取股票、期权、期货、加密货币等多品类的实时报价、历史OHLCV数据、交易记录等金融市场数据，支撑OpenClaw的交易决策、回测或机器学习数据集构建。输入需配置API密钥（S3密钥可选），输出为JSON或CSV格式。免费版提供15分钟延迟数据并有限流，实时数据需付费订阅。

Use this skill whenever OpenClaw needs stock quotes, options chains, futures prices, crypto prices, OHLCV bars, trades, or any other market data. Triggers on any request for price data, market data, historical bars, real-time streaming, or backtesting data across stocks, options, futures, indices, forex, and crypto.

Massive Data Feed Skill

Massive provides three access methods for market data:

Method	Best For
REST API	On-demand queries — quotes, OHLCV bars, historical records
WebSocket API	Real-time streaming — live trades, quotes, minute bars
Flat Files	Bulk historical downloads — backtesting, ML datasets

Setup

First-time only:

bash scripts/setup.sh

Required env vars:

MASSIVE_API_KEY=your_api_key_here
# Only needed for Flat Files:
MASSIVE_S3_ACCESS_KEY=your_s3_access_key
MASSIVE_S3_SECRET_KEY=your_s3_secret_key

Get your API key and S3 credentials at: https://massive.com/dashboard/keys

SDK Initialization (REST)

import os
from massive import Client  # massive-python-client

client = Client(api_key=os.environ["MASSIVE_API_KEY"])

Authentication (REST — Alternative: Raw HTTP)

Include your API key either as a query parameter or header:

import requests

API_KEY = os.environ["MASSIVE_API_KEY"]
BASE_URL = "https://api.massive.com/v1"

# Option A: query parameter
resp = requests.get(f"{BASE_URL}/stocks/trades", params={"apiKey": API_KEY, "ticker": "AAPL"})

# Option B: authorization header
resp = requests.get(f"{BASE_URL}/stocks/trades",
    headers={"Authorization": f"Bearer {API_KEY}"},
    params={"ticker": "AAPL"})

Reference Files — Read the relevant one before proceeding

Task	Read
Stock quotes, trades, OHLCV bars, fundamentals	`references/stocks.md`
Options chains, Greeks, trades, quotes	`references/options.md`
Futures prices and historical bars	`references/futures.md`
Crypto prices, trades, OHLCV	`references/crypto.md`
Real-time streaming via WebSocket	`references/websocket.md`
Bulk historical CSV downloads	`references/flat-files.md`

Response Format

All REST endpoints return JSON with a consistent structure:

{
  "status": "OK",
  "count": 10,
  "request_id": "abc123",
  "results": [ ... ]
}

Always check status == "OK" before using results.

Important Constraints

15-minute delayed data is available on free plans. Real-time requires a paid plan.
Rate limits apply on free plans (5 requests/minute REST). Paid plans have higher limits.
WebSocket: one concurrent connection per asset class by default. Contact support for more.
Flat Files data for each trading day is available by ~11:00 AM ET the following day.
Massive does not execute trades — pair this skill with the snaptrade-trading skill for execution.
