# Supersede a memory

POST https://api.dev.band.ai/api/v1/agent/memories/{id}/supersede

Marks a memory as superseded (soft delete). Use when information is outdated or incorrect.
The memory remains for audit trail but won't appear in normal queries.

Only the source agent can supersede.

## Authentication

- `X-API-Key` header (required) — Enter your API key for programmatic access

## Request

### Path parameters

- `id` (string, required) — Memory ID

## Response

### 200

Superseded Memory

- `data` (AgentMemory, optional) — A memory entry stored by an agent

## Errors

### 401 Unauthorized Error

Unauthorized

- `error` (ErrorError, required)

### 403 Forbidden Error

Forbidden

- `error` (ErrorError, required)

### 404 Not Found Error

Not Found

- `error` (ErrorError, required)

## Types

### AgentMemory

A memory entry stored by an agent

- `content` (string, required) — The memory content
- `id` (string, required) — Memory ID
- `inserted_at` (string, required) — When the memory was created
- `scope` (enum, required) — Visibility scope of the memory
  - Allowed values: `agent`, `subject`, `organization`
- `segment` (enum, required) — Logical segment of the memory
  - Allowed values: `user`, `agent`, `tool`, `guideline`
- `system` (enum, required) — Memory system tier
  - Allowed values: `sensory`, `working`, `long_term`
- `type` (enum, required) — Memory type within the system
  - Allowed values: `iconic`, `echoic`, `haptic`, `episodic`, `semantic`, `procedural`
- `metadata` (AgentMemoryMetadata, optional, nullable) — Additional metadata
- `organization_id` (string, optional, nullable) — Organization this memory is shared within. Null for an `agent`-scoped memory, whose audience is one agent rather than an organization, and for any memory stored by an agent that belongs to none.
- `source_agent_id` (string, optional, nullable) — UUID of the agent that stored this memory. Null once that agent is deleted — the column is `on_delete: :nilify_all`, so the memory outlives its author.
- `status` (enum, optional) — Memory lifecycle status
  - Allowed values: `active`, `superseded`, `archived`
- `subject_id` (string, optional, nullable) — UUID of the subject this memory is about (user or agent)
- `thought` (string, optional, nullable) — Agent's reasoning for storing this memory

### ErrorError

- `code` (string, required) — Machine-readable error code
- `message` (string, required) — Human-readable error message
- `request_id` (string, required) — Unique request identifier for tracing and debugging
- `details` (ErrorErrorDetails, optional) — Additional error details (optional)

### AgentMemoryMetadata

Additional metadata

### ErrorErrorDetails

Additional error details (optional)
