# Connectors, clients & APIs

Choose the right Pinot client, BI integration, query engine, processing connector, or API surface for your use case.

Apache Pinot connects to applications, BI tools, federated query engines, and stream or batch processing systems in different ways. This section is organized by user intent so you can start from what you are trying to build instead of from a legacy product bucket.

## Choose an integration path

{% content-ref url="/pages/0uQSI6w5VLSmfi1Grdgk" %}
[Client libraries](/build-with-pinot/connectors-clients-apis/client-libraries.md)
{% endcontent-ref %}

{% content-ref url="/pages/9rFyJrUzbK57lagaWrqP" %}
[BI tools](/build-with-pinot/connectors-clients-apis/bi-tools.md)
{% endcontent-ref %}

{% content-ref url="/pages/iPmyAts2Z1J2i7TGKHe5" %}
[Query engines](/build-with-pinot/connectors-clients-apis/query-engines.md)
{% endcontent-ref %}

{% content-ref url="/pages/2pWaIWuNrG25QKln5dMG" %}
[Processing connectors](/build-with-pinot/connectors-clients-apis/processing-connectors.md)
{% endcontent-ref %}

{% content-ref url="/pages/92TbIkv6v45Cq5wjR2E5" %}
[REST / gRPC APIs](/build-with-pinot/connectors-clients-apis/rest-grpc-apis.md)
{% endcontent-ref %}

## Build guidance vs API reference

This section explains when to use the REST or gRPC APIs and how they fit into application workflows. Detailed endpoint reference belongs in [Reference > API reference](/reference/api-reference.md).

## What this page covered

This page grouped Pinot integrations by the job you need done: application clients, BI tooling, federated query engines, processing connectors, and direct API access.

## Next step

Open the page that matches your integration path, such as [Client libraries](/build-with-pinot/connectors-clients-apis/client-libraries.md) or [REST / gRPC APIs](/build-with-pinot/connectors-clients-apis/rest-grpc-apis.md).

# 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.pinot.apache.org/build-with-pinot/connectors-clients-apis.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.
