 ## Helpers
 
-## Protocols
+### `get_blobs_and_kzg_commitments`
 
-### `ExecutionEngine`
+The interface to retrieve blobs and corresponding kzg commitments.
 
-#### `get_payload`
+Note: This API is *unstable*. `get_blobs_and_kzg_commitments` and `get_payload` may be unified.
+Implementers may also retrieve blobs individually per transaction.
 
-`get_payload` returns the upgraded EIP-4844 `ExecutionPayload` type.
+```python
+def get_blobs_and_kzg_commitments(payload_id: PayloadId) -> Tuple[Sequence[BLSFieldElement], Sequence[KZGCommitment]]:
+    ...
+```
