TD Ameritrade

TD Ameritrade was a US retail brokerage that provided REST APIs for trading equities and options, accessing streaming market data, managing brokerage accounts, and retrieving historical and real-time market data. Following the Charles Schwab acquisition, the TD Ameritrade API was shut down on May 10, 2024. Schwab has ported much of the original functionality into the Schwab Trader API.

TD Ameritrade publishes 13 APIs on the APIs.io network, including Instruments API, Authentication API, Accounts and Trading API, and 10 more. Tagged areas include Brokerage, Trading, Finance, Equities, and Options.

The TD Ameritrade catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

TD Ameritrade’s developer surface includes authentication, developer portal, getting-started guide, documentation, and 11 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
