# Introduction to Data Proxy

A Data proxy is a simple middleware component that acts as a pipeline or connector between a data provider and the SEDA network by holding an API key that has access to the data provider’s services. Additionally, Data Proxies verify conditions to inbound HTTP requests, checking that the requester is part of the SEDA network and that the provider’s fees have been paid. Additionally, they allow providers to add an SECP private key to the proxy, which would be used to sign the data before it’s forwarded back to the requester, adding additional security and verifiability.

In the end, the proxy nodes allow data providers to expose their entire suite of APIs through a single, one-time deployment and earn value based on onchain demand with minimal technical overhead or maintenance.

## 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://docs.seda.xyz/home/for-data-providers/operating-a-data-proxy/introduction-to-data-proxy.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.
