# Platform Features

Openfeed consolidates global exchange data through a single integration. It delivers low-latency market data in its native exchange format.

This reduces exchange-connection complexity. It also lowers development and maintenance costs.

### Core components

Openfeed includes three core components:

1. [**Openfeed Protocol**](/architecture/core-protocols.md) — protobuf-based message definitions for efficient, cross-platform market data delivery.
2. [**Streaming API**](/openfeed-api/streaming.md) — continuous real-time and delayed updates for large symbol universes. SDKs support [Java](/repos-sdks/java-sdk.md), [.NET](/repos-sdks/.net-sdk.md), [Python](/repos-sdks/python-sdk.md), and [Go](/repos-sdks/go-golang-sdk.md).
3. [**Snapshot REST API**](/openfeed-api/snapshot-rest.md) — query-response access to JSON market data for targeted requests.

### Market data coverage

Openfeed connects your applications to exchanges worldwide. Choose Level 1 data or Level 2 market depth based on your entitlement and application requirements.

Review [available exchanges](/getting-started/available-exchanges.md) and supported [subscription types](/getting-started/subscription-types.md) before you integrate.

### Flexible delivery

Connect over the internet or use dedicated connectivity options. These options support low-latency data delivery for business-critical applications.

See the [connectivity overview](/networking-options/connectivity-overview.md), [dedicated connections](/networking-options/dedicated-connections.md), and [AWS PrivateLink](/networking-options/aws-privatelink.md).

### Build and maintain less

Use documented feed handlers and SDKs to shorten initial development. The same resources reduce ongoing integration work as your product evolves.

Start with the [Quickstart](/getting-started/quickstart.md) and apply the [Best Practices](/getting-started/best-practices.md) guidance to optimize performance and stability.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/platform-features.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.
