# Abandon Agent Trajectory

POST https://api.getzep.com/api/v4/agents/{agent_uuid}/trajectories/{trajectory_uuid}/abandon
Content-Type: application/json

Reference: https://docs-beta.getzep.com/sdk-reference/agent/trajectory/abandon

## Authentication

- `Authorization` header (required) (prefixed with ` Api-Key  `) — Type "Api-Key" followed by a space and the project API key.

## Request

### Path parameters

- `agent_uuid` (string, required) — Agent UUID
- `trajectory_uuid` (string, required) — Trajectory UUID

### Body (application/json)

This endpoint expects a v4.AbandonAgentTrajectoryRequest.

- `highest_accepted_sequence` (integer, required)
- `assertion_uuid` (string, optional)
- `expected_revision` (integer, optional)
- `missing_sequence_ranges` (list of v4.AgentTrajectorySequenceRange, optional)
- `reason` (string, optional)
- `verification` (enum, optional)
  - Allowed values: `none`, `agent`, `tool`, `customer`, `external`

## Response

### 202

Accepted

- `task` (v4.Task, optional)
- `trajectory` (v4.AgentTrajectory, optional)

## Errors

### 400 Bad Request Error

Bad Request

- `error` (v4.ErrorBody, optional)

### 409 Conflict Error

Conflict

- `error` (v4.ErrorBody, optional)

## Types

### v4.AgentTrajectorySequenceRange

- `first` (integer, required)
- `last` (integer, required)

### v4.Task

- `completed_at` (string, optional) — The time the task reached a terminal status; absent while it is still in progress.
- `created_at` (string, optional) — The time the task was created.
- `error` (v4.ErrorBody, optional) — The error that caused the task to fail; also present on a partial task when the worker can name a single cause.
- `progress` (v4.TaskProgress, optional) — The last processing stage a worker reported for this task. It is not cleared when the task finishes, so a completed task may still show its final stage.
- `result` (map from string to any, optional) — Operation-specific output populated once the task reaches succeeded or partial, such as identifiers the operation could not return synchronously.
- `started_at` (string, optional) — The time a worker began processing the task; absent until then.
- `status` (string, optional) — The task's current state: pending, processing, succeeded, partial, or failed.
- `type` (string, optional) — The kind of asynchronous operation the task represents.
- `updated_at` (string, optional) — The time the task was last updated.
- `uuid` (string, optional) — The unique identifier of the task, used to poll its status.

### v4.AgentTrajectory

- `abandoned_at` (string, optional) — The time the Trajectory was abandoned.
- `agent_uuid` (string, optional) — The owning Agent UUID.
- `attempt_family_uuid` (string, optional) — The stable retry-family identity shared with declared child attempts.
- `closed_at` (string, optional) — The time the Trajectory closed.
- `created_at` (string, optional) — The time the Trajectory was created.
- `internal` (v4.AgentTrajectoryInternal, optional) — Server-owned fields that are not part of the top-level capture contract.
- `learn_from` (boolean, optional) — Whether eligible evidence may participate in learning.
- `learn_from_reason` (string, optional) — Why the Trajectory is not eligible for learning.
- `metadata` (map from string to any, optional) — Developer metadata used for exact containment filters.
- `objective` (string, optional) — The task-instance objective captured for this attempt.
- `outcome` (enum, optional) — The caller-owned task outcome.
  - Allowed values: `succeeded`, `failed`, `partial`, `abandoned`, `unknown`
- `parent_trajectory_uuid` (string, optional) — The parent attempt when this Trajectory is a retry.
- `revision` (integer, optional) — The revision required by the next update or lifecycle command.
- `source` (v4.AgentTrajectorySource, optional) — The source record for an imported Trajectory.
- `status` (enum, optional) — The current lifecycle state.
  - Allowed values: `open`, `closing`, `closed`, `abandoned`, `deleted`
- `task_family` (string, optional) — The optional opaque task-family classification slug.
- `trajectory_id` (string, optional) — The optional customer-assigned identifier, unique within the Agent.
- `updated_at` (string, optional) — The time the Trajectory was last updated.
- `uuid` (string, optional) — The stable Trajectory UUID.
- `verification` (enum, optional) — The strength of the accepted outcome verification.
  - Allowed values: `none`, `agent`, `tool`, `customer`, `external`

### v4.ErrorBody

- `code` (string, optional)
- `details` (map from string to any, optional)
- `message` (string, optional)
- `param` (string, optional)
- `request_id` (string, optional)

### v4.TaskProgress

- `stage` (string, optional) — The most recent processing stage reported by the worker handling the task.

### v4.AgentTrajectoryInternal

- `assertion_uuid` (string, optional)
- `closing_sequence` (integer, optional)
- `current_summary_version` (integer, optional)
- `last_task_uuid` (string, optional)
- `next_sequence` (integer, optional)
- `processing_state` (enum, optional)
  - Allowed values: `idle`, `pending`, `processing`, `failed`

### v4.AgentTrajectorySource

- `connection_uuid` (string, optional)
- `import_uuid` (string, optional)
- `imported_at` (string, optional)
- `kind` (enum, optional)
  - Allowed values: `trace_import`
- `provider` (string, optional)
- `provider_project_id` (string, optional)
- `run_uuid` (string, optional)
- `scores` (map from string to any, optional)
