## `/beacon/attester_slashing`
Accepts an `attester_slashing` and verifies it. If it is valid, it is added to the operations pool for potential inclusion in a future block. Returns a 400 error if the `attester_slashing` is invalid.
### HTTP Specification

| --- |--- |
Path | `/beacon/attester_slashing`
Method | POST
JSON Encoding | Object
Query Parameters | None
Typical Responses | 200/400
### Parameters
Expects the following object in the POST request body:
```
{
attestation_1: {
attesting_indices: [u64],
data: {
slot: Slot,
index: u64,
beacon_block_root: Bytes32,
source: {
epoch: Epoch,
root: Bytes32

root: Bytes32
},
target: {
epoch: Epoch,

## `/beacon/block`
Request that the node return a beacon chain block that matches the provided
criteria (a block `root` or beacon chain `slot`). Only one of the parameters
should be provided as a criteria.
### HTTP Specification
| Property | Specification |
| --- |--- |
Path | `/beacon/block`
Method | GET
JSON Encoding | Object
Query Parameters | `slot`, `root`
Typical Responses | 200, 404
### Parameters
Accepts **only one** of the following parameters:
- `slot` (`Slot`): Query by slot number. Any block returned must be in the canonical chain (i.e.,
either the head or an ancestor of the head).
- `root` (`Bytes32`): Query by tree hash root. A returned block is not required to be in the
canonical chain.
### Returns
Returns an object containing a single [`SignedBeaconBlock`](https://github.com/ethereum/eth2.0-specs/blob/v0.10.0/specs/phase0/beacon-chain.md#signedbeaconblock) and the block root of the inner [`BeaconBlock`](https://github.com/ethereum/eth2.0-specs/blob/v0.10.0/specs/phase0/beacon-chain.md#beaconblock).
