The Playground is more than just a documentation viewer—it’s a fully interactive development environment directly in your browser. It allows you to simulate complex workflows and inspect real data before you even install an SDK.

Select any endpoint from the sidebar, fill in the parameters (symbol, timeframe, etc.), and click Execute.

• No API Key Needed (Mock Mode): By default, the playground mocks responses so you can see the data structure immediately.
• Real Data: Toggle "Mock Data" OFF and enter your key (TickCatcher Direct or RapidAPI) to fetch live market data.

This is the playground's superpower. You can pipeline the output of one request (e.g., fetching Candles) directly into another (e.g., calculating RSI).

How it works:

1. Run a Candles request (e.g., Get 1hr BTC candles).
2. The response is saved to the playground's "Context".
3. Switch to an Indicator tab (e.g., RSI).
4. Instead of uploading a JSON file, simply select "Use Context Data".
5. Execute to see the RSI values calculated from your previous candle fetch.

Raw JSON is hard to read. The playground includes a specialized Table View and Chart Preview.

• Candles: Viewed as an interactive candlestick chart.
• Indicators: Viewed as line charts overlaid on price data (where applicable).

Once you are happy with your request, click the "Code" tab. The playground generates production-ready snippets for:

• TypeScript
• Python
• Go
• C#
• Java
• Swift
• Rust
• Curl

Copy and paste directly into your project.

Let's simulate a standard workflow: "Is Bitcoin overbought?"

1. Fetch Candles:

   • Go to Candles > Basic.
   • Set Symbol: BTCUSDT, Timeframe: 1h.
   • Click Execute.
   • Result: You see the last 200 hours of Bitcoin price action.

2. Calculate RSI:

   • Go to Indicators > Basic > RSI.
   • The "Candle Data" field should auto-fill with "from Context".
   • Set Period: 14.
   • Click Execute.
   • Result: You see an array of RSI values.

3. Inspect:

   • Look at the last value in the response.
   • Is it above 70? Overbought.
   • Is it below 30? Oversold.

• Mock Mode is great for checking schemas.
• Live Mode requires a valid API Key (TickCatcher Direct or RapidAPI).
• Use the History tab to revisit previous requests and compare results.
