# Connectivity Overview

Institutional clients depend on **high-quality, high-availability market data infrastructure** to support business-critical applications.

Barchart’s Openfeed platform delivers real-time data with **Level 1 and Level 2 market depth**, available through multiple connectivity options including public internet access, private cloud networking, and dedicated cross-connects.

With well-documented protocols and feed handlers, Openfeed minimizes development and operational overhead, allowing teams to spend less time managing infrastructure and more time building products, serving clients, and growing their business.

To support a wide range of technical environments and performance requirements, Barchart offers several connectivity models for accessing Openfeed services.

Clients can choose the architecture that best fits their infrastructure, latency targets, and security policies—from standard internet connections to private cloud networking or ultra-low-latency colocation links. The sections below outline these connectivity options and summarize their typical use cases, performance characteristics, and deployment considerations.

**Connectivity Options**

## 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/networking-options/connectivity-overview.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.
