What is Tranc?

Tranc is a B2B SaaS API that delivers trading indicators as LLM-optimized JSON to day-trading agents. It is designed to be the fastest, most cache-efficient source of machine-readable market signals.

​
Why Tranc?

Standard financial data APIs return raw OHLCV data and leave your agent to implement indicator math, interpret values, and format the output. Tranc does all of that for you:
  • Pre-computed indicators — RSI, MACD, Bollinger Bands, and 16 more, freshly computed from live exchange feeds.
  • LLM-native responses — every response includes signal (a short classification) and hint_for_llm (a one-sentence interpretation you can inject directly into your prompt).
  • Staleness guards — stale: true tells your agent not to trade on outdated data. No guessing.
  • Sub-50ms cached latency — your agent doesn’t wait for indicator math; results are cached in Redis and served at cache speed.

​
How it works

Your LLM agent
  → GET /v1/indicator/rsi?symbol=BTC-USD&tf=5m
  ← { "value": 68.3, "signal": "overbought_approaching", "hint_for_llm": "RSI climbing toward overbought. Consider caution on long entries.", "stale": false }
