# Threads

Learn how concurrent threads work with DataImpulse proxies. Understand thread limits, parallel connections, and how to optimize throughput for your use case.

Each plan has a limit of 2000 threads. A thread represents an active connection to a proxy. If the maximum number of simultaneous connections is reached, the service will return an error `407 THREADS_EXHAUSTED` .

If you need to increase this limit, please contact our Support team.

For security purposes, users need to complete KYC verification before their increasing request is approved.

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.dataimpulse.com/proxies/threads.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
