# validators - Cosmos

Example code for the validators JSON-RPC method. Complete guide on how to use validators JSON-RPC in GetBlock Web3 documentation.

Returns the validator set at a specific height. The set is paginated — use `page` and `per_page` to traverse beyond the first results.

## Parameters

| Parameter | Type    | Required | Description                                 |
| --------- | ------- | -------- | ------------------------------------------- |
| height    | integer | No       | Block height (defaults to latest)           |
| page      | integer | No       | Page number (default: 1)                    |
| per\_page | integer | No       | Validators per page (default: 30, max: 100) |
