# InsightSentry

We provide unified access to data from **150+ global exchanges and venues** across multiple asset classes:

* Foreign Exchange (FX)
* Bond
* Cryptocurrencies
* Economic Data
* Options
* Screeners

---

## Data Access Methods

* **REST API** – Flexible access with multiple timeframes.
* **WebSocket API** – Real-time streaming data (tick, second, minute, hour, day, week, month).
* **Long Polling (via REST API)** – Real-time updates without WebSocket, enabled by passing `long_poll=true`.

---

## Historical and Real-Time Data

* **Historical coverage:** Over **20 years** of data for many asset classes, up to **minute-level granularity**.
* **Real-time granularity:** Tick-level (microsecond precision), second-level, and custom intervals.
* **Flexible timeframes:** Request any interval using:

  * `bar_type` = tick, second, minute, hour, day, week, month
  * `bar_interval=<number>`
    Developers don’t need to handle manual timeframe conversions.
* **Real-time WebSocket updates:** Data is pushed on every price or volume change, not only at interval boundaries.
