Charles Schwab Data Parser & API

Charles Schwab is the largest US retail brokerage and RIA custodian by client assets, and StockAPIS extracts its market data — real-time quotes, OHLC candles, full option chains, mutual fund NAVs and account positions — through a single REST API. Schwab offers an official Trader API (inherited from the TD Ameritrade / thinkorswim platform after the 2020 acquisition), and StockAPIS normalizes it to the same schema you use for every other broker, so you query Schwab, Interactive Brokers and E*TRADE the same way without maintaining separate OAuth integrations.

Platform Overview

Market Position

• The largest US retail broker and RIA custodian by client assets (~$9T+ across millions of accounts)
• Absorbed TD Ameritrade and its thinkorswim trading platform, consolidating two of the biggest US brokerages
• Coverage spans US equities, ETFs, options, an extensive mutual fund marketplace, fixed income and futures
• Official OAuth-based Trader API for quotes, history, option chains and account data — wrapped by StockAPIS’s unified normalization

Data Coverage

StockAPIS exposes the full Charles Schwab data surface:

• Quotes — real-time and delayed last price, bid/ask, net change, volume and day range for stocks, ETFs and options
• Price history — OHLC candles across intervals (1m → monthly) for charting, backtesting and technical analysis
• Option chains — full chains with strikes, expirations, greeks, implied volatility, open interest and bid/ask
• Mutual funds — fund NAVs, performance history, expense ratios and Schwab marketplace metadata
• Accounts & positions — holdings, positions, balances and transaction history (OAuth-scoped)
• Instruments — symbol search, fundamentals and instrument metadata

Quick Start

import stockapis
 
client = stockapis.Client(api_key="your-api-key")
 
# Real-time quote for a US equity via Charles Schwab
aapl = client.charles_schwab.get_quote(symbol="AAPL")
print(f"AAPL: ${aapl['lastPrice']}  ·  {aapl['netChangePercent']}% today")

const { StockAPIS } = require("stockapis");
const client = new StockAPIS({ apiKey: "your-api-key" });
 
// Full option chain for a symbol
const chain = await client.charlesSchwab.getOptionChain({
  symbol: "AAPL",
  contractType: "CALL",
  expiration: "2024-06-21",
});
console.log(chain.calls[0]);

Frequently Asked Questions

Does Charles Schwab have an official API? Yes — Schwab provides an official OAuth-based Trader API (the successor to the TD Ameritrade / thinkorswim API) for quotes, price history, option chains and account data. StockAPIS wraps it in a unified schema so Schwab data matches every other source you pull.

What data can I get from Charles Schwab through StockAPIS? Real-time and delayed quotes, OHLC price history, full option chains with greeks, mutual fund NAVs and performance, plus OAuth-scoped account positions, balances and transactions across US equities, ETFs, options and futures.

Can I access my Schwab account positions through StockAPIS? Yes — account, position and balance endpoints are available once you complete the Schwab OAuth flow; StockAPIS normalizes the response so it lines up with positions from other brokers you connect.
