✓ This is the authoritative definition for this NSID.

## Description

Paginated forward read of an op log scoped to an explicit block set. Pull-based alternative to opening a `page.corvus.subscribeOps` WebSocket at `cursor: 0` — same op shape, same cursor semantics, just delivered as a query page instead of a live tail. Each entry is a `page.corvus.subscribeOps#op` so live and historical paths feed the same applier.

Like `subscribeOps`, this query does NOT walk graph relations. Callers fetch ops for the blocks they care about and follow refs explicitly with subsequent calls.

## Definitions

### `page.corvus.getOps`

**Type**: `query`

Read ops for the requested `blockIds` in forward cursor order, strictly after `cursor`.

#### Parameters

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `limit` | `integer` | No | Maximum number of ops to return in this page. |
| `cursor` | `integer` | No | Server-assigned cursor (exclusive) to resume from. Omitted = start from cursor 0 (every op the server has for the requested blocks). Same semantic as `page.corvus.subscribeOps#main.cursor`. |
| `blockIds` | `array` | Yes | The explicit set of block ids to read ops for. No transitive walk — only ops whose `blockId` is in this set are returned. |
| `includeDids` | `array` | No | The dids of the users to include. |

#### Output

**Encoding**: `application/json`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `ops` | `array` | Yes | Ops for the requested blocks with cursor strictly greater than the input `cursor`, in ascending cursor order. Up to `limit` entries. Shape is identical to a live `page.corvus.subscribeOps#op` frame. |
| `cursor` | `integer` | No | Cursor of the last op in `ops`. Pass this as `cursor` on the next call to continue paginating. Omitted when `ops` is empty (caller is caught up to the server's high-water for these blocks). |

#### Errors

- **InvalidCursor**: The supplied cursor is malformed or beyond the server's current high-water.
