The TOS Indicators API

One programmatic entry point to the signal engines behind the indicator suite. For members and teams who want the same signals their charts show, in code.

What the API returns

  • Cross product signals. Query the engines behind the suite from one place instead of one integration per product.
  • Signal state. What is active right now on a symbol, with direction and timing.
  • History. Past signals and how they resolved, for research and backtesting.
  • Symbol coverage. What each engine supports, so a job knows what it can ask for.
  • Webhooks. A push when a signal fires, with no polling.

Questions

What is the TOS Indicators API?

It is the developer interface to TOS Indicators. A REST API and webhooks that expose the engine output as structured data, so you can research and trade programmatically.

Does it work with Claude and OpenAI?

Yes. Responses carry structured fields and a plain language summary, so agents can consume them directly. An MCP server is planned for early access.

Do I get the logic behind the signals?

No. The API returns the output of the engine, not the rules that produce it, so you can build on the signals without the method being exposed.

How is it priced?

It is a paid product with tiers for individual traders and for teams building on the data. Join the list for pricing and early access details.
