# Market Replay API

Welcome to Barchart's **Market Replay Technical Documentation.**

Market Replay's API provides access to a comprehensive historical market data archive. This platform delivers point-in-time quote, trade, OHLC, and market statistics data across global asset classes.

Built directly from Barchart's real-time market data infrastructure, Market Replay allows developers, quantitative researchers, risk managers, compliance teams, and data engineers to retrieve historical market conditions exactly as they existed at a specific moment in time.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developer.barchart.com/market-replay-docs/apis.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
