# Add episode

POST https://api.getzep.com/api/v4/graphs/{graph_uuid}/episodes
Content-Type: application/json

Reference: https://docs-beta.getzep.com/sdk-reference/graph/episode/add

## Authentication

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

## Request

### Path parameters

- `graph_uuid` (string, required) — Graph UUID

### Body (application/json)

This endpoint expects a v4.AddEpisodeRequest.

- `data` (string, required) — The episode content to add to the graph.
- `created_at` (string, optional) — The episode's reference time, used for temporal reasoning rather than ingestion time.
- `document_id` (string, optional) — Groups this episode as a chunk of a document on the graph.
- `metadata` (map from string to any, optional) — Metadata to store on the episode. Max 10 keys. Values must be strings, numbers, booleans, or arrays of scalars.
- `source_description` (string, optional) — A description of the source of this episode.
- `strict_ontology` (boolean, optional) — When true, prevents extraction of generic entity nodes that do not match the configured ontology.
- `type` (enum, optional) — The data format of the episode: text, json, or message. Defaults to text.
  - Allowed values: `text`, `json`, `message`

## Response

### 202

Accepted

- `episode` (v4.Episode, optional) — The newly created episode, a full resource that is readable immediately. Its processed field is false until graph extraction finishes.
- `task` (v4.Task, optional) — The asynchronous task that tracks the episode's graph extraction and indexing.

## Errors

### 400 Bad Request Error

Bad Request

- `error` (v4.ErrorBody, optional)

### 401 Unauthorized Error

Unauthorized

- `error` (v4.ErrorBody, optional)

### 403 Forbidden Error

Forbidden

- `error` (v4.ErrorBody, optional)

### 404 Not Found Error

Not Found

- `error` (v4.ErrorBody, optional)

### 409 Conflict Error

Conflict

- `error` (v4.ErrorBody, optional)

## Types

### v4.Episode

- `content` (string, optional) — The raw content of the episode.
- `content_policy` (v4.EpisodeContentPolicy, optional) — The content policy state of the episode, present only on a graph with a bound content policy rule.
- `created_at` (string, optional) — The time the episode was created.
- `document_id` (string, optional) — The developer-assigned identifier of the document this episode belongs to, present only for episodes added to a document.
- `graph_uuid` (string, optional) — The unique identifier of the graph this episode belongs to.
- `metadata` (map from string to any, optional) — Custom metadata associated with the episode.
- `processed` (boolean, optional) — Whether the episode has finished graph extraction and indexing.
- `relevance` (double, optional) — A cross-encoder-derived relevance score, present only when the cross-encoder reranker scored this result; like score, it is omitted from plain list results.
- `role` (enum, optional) — The role of the episode's sender, present only when the episode was added as a message.
  - Allowed values: `system`, `assistant`, `user`, `function`, `tool`
- `role_name` (string, optional) — The free-form display name of the episode's sender, present only when the episode was added as a message.
- `score` (double, optional) — The ranking score returned with every search result; omitted when the episode appears in a plain list rather than a search result.
- `source` (enum, optional) — The format of the episode's content: text, json, or message.
  - Allowed values: `text`, `json`, `message`, `fact_triple`
- `source_description` (string, optional) — A free-form description of where the episode's content came from.
- `thread_uuid` (string, optional) — The thread this episode belongs to, present only for episodes added to a thread.
- `uuid` (string, optional) — The unique identifier of the episode.
- `valid_at` (string, optional) — The time the episode's content became true or was observed, used for temporal reasoning.

### 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.ErrorBody

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

### v4.EpisodeContentPolicy

- `category_keys` (list of string, optional) — The keys of the categories with a matched rule.
- `dropped_count` (integer, optional) — The number of derived candidates that were dropped.
- `retained_count` (integer, optional) — The number of derived candidates that were published to the graph.
- `revision` (integer, optional) — The project revision number of the policy the graph bound.
- `status` (enum, optional) — The evaluation status. pending means the evaluation has not finished, complete means every candidate was evaluated and the graph batch was written, and failed means ingestion retries were exhausted.
  - Allowed values: `pending`, `complete`, `failed`
- `violated` (boolean, optional) — Whether at least one derived candidate matched a rule. Once true, it stays true.

### v4.TaskProgress

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