Your Charles Schwab API Infrastructure
Any Language. Production-Ready.
The only Schwab API client that survives the 7-day refresh token expiry.
Quant.Infra.Net.Pro is a local trading software license for self-directed users. It helps you connect your own Schwab account and API credentials; we do not custody funds, open accounts, place trades for you, manage assets, or provide investment advice.
If Any of These Ring True, We've Got You Covered
You want to use Schwab data for your strategies. You don't want to become an API integration expert.
Your Strategy Should Be Running on the Market, Not Stuck on API Problems
Weeks of Engineering, Not Hours
Think it's just a simple API call? Schwab's auth involves multi-layered token mechanisms with complex expiry policies. Most developers spend weeks or months getting it stable — time you could have spent writing strategies, running backtests, and going live.
The 7-Day Curse That Chains You to Your Desk
Schwab's token expires every 7 days. Without automatic renewal, your pipeline stops dead weekly — no orders, no quotes, no signals. No vacations, no weekends off, always watching. Quant.Infra.Net.Pro is the solution that breaks this wall.
Deploy Once, Call from Any Language — We Handle the Rest
Deploy the Web API once. Call our endpoints from any language. Never think about token management again.
Your Language, Your Pace
- Python, Java, Go, Node.js, C# — write in your language of choice, an HTTP call is all it takes
- Accounts, quotes, orders, positions, current option chains, and equity/ETF price history — RESTful endpoints with Swagger docs
- Price history follows Schwab limits: equities and ETFs only. Options, futures, and historical option chains are not provided.
- No .NET SDK, no compilation, no integration library — just HTTP requests
Never Chained to the 7-Day Curse Again
- Tokens stay valid — take vacations, sleep soundly, your pipeline keeps running
- Zero manual intervention — deploy it and forget it, the system handles everything
- Instant recovery after restarts — server reboots and migrations? No problem
Production-Ready, Right Out of the Box
- Graceful error recovery — your pipeline keeps running through any disruption
- Built-in redacted logging and license telemetry for monitoring integration health without exposing sensitive Schwab data in normal logs
- Ready out of the box with production defaults
Always Improving. Every Release Documented.
The latest highlights from the product. Every version's full notes are on the version history page.
Read-only MCP server for AI clients
Let Claude Code, Cursor and other AI clients read your Schwab accounts, positions, orders, quotes and option chains. Off by default, protected by a bearer token, and no tool can place, change or cancel an order.
Trusted HTTPS, no more "Not secure"
A local certificate authority now signs the HTTPS certificate, and on Linux it is trusted in Chrome automatically. Also fixes the in-app update check and HTTP-to-HTTPS redirects behind nginx or Apache.
One-click in-app upgrade
Update from inside the app, with a trading safety gate (no upgrades during a rebalance, pending orders or market hours) and an automatic backup of your settings before every upgrade.
Program / data separation
Settings and strategy data now live in your user data folder, so upgrades can never wipe them. Includes a one-time automatic migration and export / import of all settings.
From Zero to Production in 3 Steps
Deploy, configure, and start building. No .NET/C# knowledge required on your side.
