# /eth/v1/validator/register\_validator

Prepares the beacon node for engaging with external builders. The information must be sent by the beacon node to the builder network. It is expected that the validator client will send this information periodically to ensure the beacon node has correct and timely registration information to provide to builders. The validator client should not sign blinded beacon blocks that do not adhere to their latest fee recipient and gas limit preferences.

Note that only registrations for active or pending validators must be sent to the builder network. Registrations for unknown or exited validators must be filtered out and not sent to the builder network.

## 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.blockpi.io/build/api-reference/ethereum/ethereum-beacon-api/eth-v1-validator-register_validator.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.
