What it does
Tradier provides brokerage accounts, partner-platform connections and APIs for developers. Users can choose an interface separately from the brokerage behind it. Personal API tools, distributed partner applications and adviser integrations have distinct access routes.
For a personal tool, open a brokerage account and use its API Settings page to obtain the sandbox token. Sandbox quotes are delayed 15 minutes. The live environment uses a different token and base address. Public applications require Partner status and OAuth authorization; a personal token gives full account access and should remain private.
Brokerage plan comparison
| Plan | Monthly fee | Stocks | Equity and ETF options |
|---|---|---|---|
| Lite | US$0 | US$0.35 per trade | US$0.35 per contract |
| Pro | US$10 | US$0 | US$0 |
| Pro Plus | US$35 | US$0 | US$0 |
All include web, mobile and API access. Paid plans add desktop access; index options, futures, regulatory and account charges have separate schedules. A new-customer two-month paid-plan promotion requires a US$500 deposit within 30 days, then renews at the normal plan price.
Check the permitted-country list before applying. It includes Slovenia, while India residents cannot use margin or options. The API covers US equities, ETFs and options with Level 1 data; it does not provide Level 2 depth or historical expired-option data. Preview an order and inspect its returned status separately from the HTTP response.
