FAQ

Here are some of the most frequently asked questions to service and support representatives of the Tradier API. If you have a question and can't find your answer here, feel free to reach out to us using email at [email protected].

Can I access streaming in the paper trading environment?

Presently, we do not offer a delayed streaming endpoint for paper trading.

Can I distribute my application?

Unless you are a Tradier Partner, Tradier APIs are entitled for personal use only. If you would like to become a Tradier Partner, please contact us using our contact form.

Do you get data from [insert foreign exchange here]?

We presently support US-based equities and options data only. This includes US-based ETFs.

Do you offer Level 2 data?

We offer Level 1 data only.

Do you offer extended hours market trading?

Yes, you can send pre or post durations to trade during pre/post market sessions.

How much time is the delayed data delayed?

We delay our market data the industry standard 15-minutes for all sandbox data. In the production environment index data is also subject to the 15-minute delay.

I am getting an error from the API. Can you help?

Yes we can! However, most error messages from our API are descriptive enough to give you an idea of what's going on. If you want us to take a look, please send the error response and the API request URL to [email protected].

Tokens expire in 24 hours, but I need continuous access.

That is only the case for access tokens that our partner integrations use. If you are an individual user getting your API token from your settings page (https://web.tradier.com/user/api) your tokens never expire. For partners using OAuth this is the case but if you need continuous access without a user continually authorizing your application, we can enable refresh tokens for your application. There is an approval process, so please email [email protected].

What does it cost to use your API?

We don't charge Tradier Brokerage account holders for API access to their account.

What does this error mean: 'invalid api call as no apiproduct match found'?

Most likely, you're either attempting call and API endppoint that does not exist or a production API endpoint with a paper trading access token. In either case check the API call you're making for a valid URL and token.

Where can I find my OAuth key/secret?

If you're a Tradier Partner, you can find this information on your organization dashboard. If you're a Tradier Brokerage user, OAuth is not enabled for this type of API access as it is available for personal use only.

Where is paper trading?

All Tradier Brokerage account holders can create a paper trading account from the WebUI account drop down, or via the API by using the prefix sandbox.tradier.com/v1 with any endpoint.

Will you increase the rate-limits for my application?

Most likely not. The rate-limits have proven to be loose enough to promote innovation without being too restrictive.

Will your API work with [insert language here]?

If your language can make HTTP requests, it can connect to the Tradier API.
