+
+summary: Create a Data Deletion Job
+
+description: |
+  To permanently delete signals data, send a POST request to
+  `/v1/signals/deletions`.
+
+  Two deletion types are supported:
+
+  - `agent` — deletes sessions, dialogues, and signal reports for one agent.
+    Requires `agent_id`. The agent's data is hidden immediately and signals
+    collection is disabled for the agent, even if the job later fails. Wait
+    until the job is complete before enabling signals for the agent again.
+  - `inference` — deletes sessions, dialogues, and signal reports for the
+    team's Serverless Inference requests made before the deletion. Signals
+    continues to analyze new requests.
+
+  Deletion is permanent and cannot be undone. The job runs asynchronously;
+  poll the get endpoint to check status. To retry a failed job, send the same
+  request again. Export files created earlier are not deleted and remain
+  available until they expire.
+
+  The endpoint is idempotent: if a queued or running job already exists for
+  the same target, it is returned with `200 OK`. A new job returns
+  `202 Accepted`. Each team can have a limited number of active jobs;
+  requests beyond that limit return `429 Too Many Requests`.
