The Indicators API is a high-performance, stateless calculation engine. It allows you to transform raw OHLCV market data into actionable technical analysis signals.

Unlike the Candles API, the Indicators API does not satisfy the request by fetching data from our database. Instead, it follows a "Pipe-and-Filter" architecture:

1. You Provide Data: You send a JSON body containing an array of candle data (from our Candles API, or any other source).
2. We Calculate: Our engine validates the data and applies the requested mathematical formula (e.g., RSI, MACD).
3. We Return Results: You receive the calculated values for every candle provided.

Method: POST (All endpoints)

Headers:

• Content-Type: application/json
• X-TickCatcher-Key: YOUR_KEY
• X-RapidAPI-Key: YOUR_KEY (Optional, if using RapidAPI)

Body Schema:

{
  "data": [
    // Array of Candle Objects (Ordered by Time ASC)
    { "ts": 1600000000, "open": 100, "high": 105, "low": 95, "close": 102, "volume": 500 },
    { "ts": 1600003600, "open": 102, "high": 104, "low": 101, "close": 103, "volume": 450 }
    // ...
  ],
  "params": {
    // Specific parameters for the indicator
    "period": 14,
    "source": "close"
  }
}

We strictly categorize indicators by computational complexity.

Here is a complete end-to-end example using TypeScript:

import { IndicatorsApi, CandlesApi } from "tickcatcher";
 
// 1. Get Candles
const candles = await new CandlesApi(config).basicCandles({ symbol: "BTCUSDT", timeframe: "1h", limit: 100 });
 
// 2. Calculate RSI
const values = await new IndicatorsApi(config).rsi({ 
    rsiRequest: {
        data: candles, 
        params: { period: 14 }
    }
});
 
console.log(`Current RSI: ${values[values.length - 1]}`);
