+# `linea_getTransactionExclusionStatusV1`
+
+Queries a temporary database maintained by the transaction exclusion API service to check if a 
+transaction was rejected for exceeding data line limits that would prevent the prover from 
+by the sequencer, edge nodes, or RPC nodes.
+
+:::
+
+You can only check for transaction rejection within seven days of the transaction attempt. Querying
+transactions older than this will return a `null` response.
+
+:::
+
+If the transaction was rejected, the API call will be successful and provide the reason. 
+
+If the transaction is rejected, the API call will succeed and provide the reason; otherwise, it
+will return `null`.
+
+## Parameters
+
+`txHash`: [Required] The hash of the subject transaction.
+
+## Returns
+
+- `txHash`: The hash of the subject transaction. 
+- `from`: The public address of the account that sent the transaction. 
+- `nonce`: Number of transaction made by the sender, in hexadecimal format. 
+- `txRejectionStage`: A string detailing the point at which the transaction was rejected. One of:
+    - `SEQUENCER`: Rejected by the sequencer.
+    - `RPC`: Rejected by an RPC node (e.g. `https://rpc.linea.build`).
+    - `P2P`: Rejected by a P2P-connected node (e.g. an edge node). 
+- `reasonMessage`: Explains why the transaction was rejected. 
+- `blockNumber`: The block that the transaction was rejected from, in hexadecimal format. Only 
+returned for transactions rejected by the sequencer. 
+- `timestamp`: Time of rejection, in ISO 8601 format.

+        ```json
+        {
+            "jsonrpc": "2.0",

+                "txRejectionStage": "SEQUENCER",
+                "reasonMessage": "Transaction line count for module ADD=402 is above the limit 70",
+                "blockNumber": "0x3039",
+                "timestamp": "2024-08-22T09:18:51Z"

+        }
+        ```
+    </TabItem>
+</Tabs>
+
+:::note
+
+This example is purely representative; the database retains transaction data for only seven days, so
+you'll be unable to reproduce this response with the above example.
+
+:::
+
+If a transaction was not rejected for exceeding line limits, it will not be found in the database, 
+and a `null` result is returned. For example:
+
+```json
+{
+    "jsonrpc": "2.0",
+    "id": 1,
+    "result": null
+}
+```
+
+A similar `null` result is also returned if the transaction is older than seven days.
