# List agent knowledge snapshots

GET https://api.v2.rasen.ai/v1/agents/{agent_id}/knowledge/snapshots

Immutable selections, newest first. No source content or storage location. ID-list filters use repeated query names. Raw supplied ID count across fields is at most 100. Cursor binds normalized filters; filtered lists are not exact batch retrieval.

Reference: https://docs.v2.rasen.ai/api-reference/agents/knowledge-snapshots/list

## Authentication

- `Authorization` header (bearer token, required) — Create and manage workspace-owned keys through the existing app session routes, outside this public API. Creator and manager identities are audit actors only. Key validity follows workspace policy, expiry and explicit revocation, independently of creator membership. Do not include a workspace-selection header.

## Request

### Path parameters

- `agent_id` (string, required) — Resource identity within the authenticated workspace.

### Query parameters

- `limit` (integer, optional, default: 50) — Page size; 50 by default, at most 200.
- `cursor` (string, optional) — Opaque cursor bound to the workspace, every filter, grouping and limit. Send them unchanged with it. Expires after 24 hours.
- `snapshot_id` (list of string, optional) — Repeat the query name for multiple IDs. OR within this field; AND across fields. Maximum 100 raw ID entries total across all ID filters. Blank values are invalid. Unknown/inaccessible IDs produce no rows, not an existence disclosure. An empty array is invalid and refused: SDKs refuse it before sending, and the server refuses an empty or blank value. Omission means no filter.

## Response

### 200

List agent knowledge snapshots.

- `items` (list of KnowledgeSnapshot, required)
- `next_cursor` (string, required, nullable) — Opaque continuation cursor. Null means the last page.

## Errors

### 400 Bad Request Error

Invalid input or cursor. Correct the request.

- `error` (ErrorResponseError, required) — Only code and message are required. Rasen sends details, request_id and retry on every error, but clients must parse an error that lacks them, so a typed error is never lost to a parsing failure.

### 401 Unauthorized Error

Invalid, expired or revoked API key. Creator departure or membership changes do not invalidate a workspace key.

- `error` (ErrorResponseError, required) — Only code and message are required. Rasen sends details, request_id and retry on every error, but clients must parse an error that lacks them, so a typed error is never lost to a parsing failure.

### 403 Forbidden Error

Operation not allowed by current credential or workspace access.

- `error` (ErrorResponseError, required) — Only code and message are required. Rasen sends details, request_id and retry on every error, but clients must parse an error that lacks them, so a typed error is never lost to a parsing failure.

### 404 Not Found Error

Resource absent or not visible in this workspace.

- `error` (ErrorResponseError, required) — Only code and message are required. Rasen sends details, request_id and retry on every error, but clients must parse an error that lacks them, so a typed error is never lost to a parsing failure.

### 429 Too Many Requests Error

Rate limited. Respect Retry-After and retry the same intent where permitted.

- `error` (ErrorResponseError, required) — Only code and message are required. Rasen sends details, request_id and retry on every error, but clients must parse an error that lacks them, so a typed error is never lost to a parsing failure.

### 500 Internal Server Error

Internal error. The effect may have happened. Retry the same request with the same Idempotency-Key; read the resource before creating a new intent. For an operation that takes an Idempotency-Key, a client retry with the same key is safe: the server replays the stored outcome if the first attempt took effect; if the first attempt had no effect, the retry performs the operation once. Never retry with a new key.

- `error` (ErrorResponseError, required) — Only code and message are required. Rasen sends details, request_id and retry on every error, but clients must parse an error that lacks them, so a typed error is never lost to a parsing failure.

### 503 Service Unavailable Error

Service unavailable. Respect Retry-After where present. For an operation that takes an Idempotency-Key, a client retry with the same key is safe: the server replays the stored outcome if the first attempt took effect; if the first attempt had no effect, the retry performs the operation once. Never retry with a new key.

- `error` (ErrorResponseError, required) — Only code and message are required. Rasen sends details, request_id and retry on every error, but clients must parse an error that lacks them, so a typed error is never lost to a parsing failure.

## Types

### KnowledgeSnapshot

Immutable snapshot of exact source revisions. Does not expose embedding models, index storage URIs or document content.

- `id` (string, required) — Opaque snapshot identifier. Do not parse its contents.
- `agent_id` (string, required) — Opaque agent identifier. Do not parse its contents.
- `source_ids` (list of string, required)
- `created_at` (datetime, required)
- `source_revisions` (list of KnowledgeSnapshotSourceRevisionsItems, required)

### ErrorResponseError

Only code and message are required. Rasen sends details, request_id and retry on every error, but clients must parse an error that lacks them, so a typed error is never lost to a parsing failure.

- `code` (string, required) — Stable code. Branch on code (and details.reason for conflict), never on message. Each code has one HTTP status; see components.x-error-catalog.
- `message` (string, required) — Safe description; no provider payload or submitted secrets.
- `details` (map from string to any, optional) — Safe code-specific details. The public fields for each code are listed in components.x-error-catalog. Details never contain a request fingerprint, a hash of a request, secret material or another tenant's data. forbidden may include required_capabilities (a list).
- `request_id` (string, optional) — Same value as the X-Request-Id header. Quote it to support.
- `retry` (string, optional) — Retry class of this code: no (fix the request or state first), yes (retry the same request and the same Idempotency-Key), retry_after (wait for Retry-After, then retry the same request). Open response vocabulary. Preserve unknown values; never assume they mean success.

### KnowledgeSnapshotSourceRevisionsItems

- `source_id` (string, required)
- `revision` (string, required)
