# Dev Update #13

Hey :wave:
For the last two weeks, I have been ironing out the [`attestation_rewards`](https://github.com/sigp/lighthouse/pull/3822) API. Also, I have been testing the endpoint manually, and the data is the same comparing it to beaconcha.in.

In *this* update, I want to cover the 4 cases the `attestation_rewards` falls into:
- [validator voted correctly](#Validator-voted-correctly-),
- [validator didn't vote correctly](#Validator-didn’t-vote-correctly-),
- [validator gets penalized](#Validator-gets-penalized-), and
- [validator is not eligible](#Validator-is-not-eligible-).

The following data is from *epoch x*. beaconcha.in uses a different approach, so we need to compare the API data with *epoch x+2* from beaconcha.in.

## Validator voted correctly :heavy_check_mark:
Query:

$ curl --data "[1234, 5678]" -H "Content-Type: application/json" "http://localhost:5052/eth/v1/beacon/rewards/attestations/179090" | jq

Output:

{
  "execution_optimistic": false,
  "data": {
    "ideal_rewards": [], // ommitted
    "total_rewards": [
      {
        "validator_index": "1234",
        "head": "3225",
        "target": 6451,
        "source": 3468
      },
      {
        "validator_index": "5678",
        "head": "3225",
        "target": 6451,
        "source": 3468
      }
    ]
  }
}

## Next steps

I am happy that I finally got the API working. However, I still need to dig deeper into the data to ensure it works as intended.
