# List citation observations

> List retained citation observation metadata within accessible projects.

`list_citation_observations`

List retained citation observation metadata within accessible projects. Expired bodies remain explicitly expired; no engine measurement starts.

<Note>Available in the deployed MCP and HTTP bundle. Confirm access and inputs with your connected catalog. Workspace scopes and enabled providers still apply.</Note>

| Access         | Behavior         |
| -------------- | ---------------- |
| `watches:read` | Reads saved data |

This read does not start a verification job.

## Example request

Connect through [MCP](/guides/connect-mcp), [CLI](/guides/connect-cli), or [HTTP](/guides/connect-http). Replace example identifiers with records from your workspace.

<CodeGroup>
  ```json MCP theme={null}
  {
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/call",
    "params": {
      "name": "list_citation_observations",
      "arguments": {
        "projectId": "project_example",
        "limit": 20
      }
    }
  }
  ```

  ```bash CLI theme={null}
  agentlinkops call list_citation_observations --args '{"projectId":"project_example","limit":20}'
  ```

  ```bash HTTP theme={null}
  curl "$AGENTLINKOPS_API_URL/v1/commands/list_citation_observations" \
    -H "Authorization: Bearer $AGENTLINKOPS_API_KEY" \
    -H 'Content-Type: application/json' \
    --data '{"projectId":"project_example","limit":20}'
  ```
</CodeGroup>

## Returned result

Illustrative data validated against the documented response schema. IDs and dates are examples, not a live account capture. MCP returns this data in `structuredContent` and in a text content block; generic HTTP and CLI return the JSON result directly.

## Input fields

Omit optional fields when you do not want to supply them. Null is accepted only where listed. Unknown input properties are rejected.

| Field       | Type    | Presence | Meaning and constraints                                                                                           |
| ----------- | ------- | -------- | ----------------------------------------------------------------------------------------------------------------- |
| `projectId` | string  | Optional | Identifier of the project returned by its create or list operation. minLength: 1; maxLength: 200                  |
| `epochId`   | string  | Optional | Identifier of the epoch returned by its create or list operation. minLength: 1; maxLength: 200                    |
| `cellId`    | string  | Optional | Identifier of the cell returned by its create or list operation. minLength: 1; maxLength: 4096                    |
| `cursor`    | string  | Optional | Opaque continuation returned by this same listing; omit for the first page. maxLength: 4096                       |
| `limit`     | integer | Optional | Maximum rows in this page or bounded report; subject to the schema maximum. minimum: 1; maximum: 100; default: 50 |

### Validation and omitted values

Lists scoped observation metadata with a query-bound cursor. Expired bodies remain labeled expired; listing starts no measurement.

### Defaults when omitted

| Field   | Default |
| ------- | ------- |
| `limit` | `50`    |

## Output fields

Fields inside optional or nullable parents apply only when that parent exists. [Common schema conventions](/reference/schemas) explain evidence states, empty lists and extensions.

* **`observations`** (array, required).
* **`cursor`** (string / null, required).

## Errors and retries

The command is annotated idempotent. Reuse an accepted idempotency key when the input provides one; changing the payload under a reused key can conflict.

See [error recovery](/reference/errors) for status, scope, cooldown, cursor and retry handling. Unknown observations are result data and do not establish loss.

## HTTP resource routes

This operation has no separate resource alias. Use its generic command route in a matching environment.
