`x_batch` · Write on X (creates a job)

One X write operation (post_set_like, user_set_follow, dm_send, post_reply…) over up to 1 000 items. Give items [{account, args}] or a selector {account_ids, group_ids} plus args_list (every account × every args). Each item is queued like a direct call (same limits, run hours, do-not-contact). Optional spacing_seconds {min,max} between items of the same account. dry_run=true returns what would be queued and why any item is refused. Follow with x_batch_get; the batch.completed event fires when every item has ended.

## Input {#input}

| Field | Type | Required | Description |
|---|---|---|---|
| `operation` | string (0–64 chars) | Yes | Operation id of an X write that takes an account (see tools_search). |
| `items` | array of object (0–1000 items) | No |  |
| `selector` | object | No | Which accounts: the union of account_ids and the members of group_ids. Empty = no account (never all). |
| `args_list` | array of object (0–1000 items) | No | With selector: each args object runs on every selected account. |
| `spacing_seconds` | object | No | Extra wait between two items of the same account (default none: the account's own queue order and human pacing only). |
| `dry_run` | boolean | No |  |

## Result {#output}

Creates a job for the X account's VPS. REST waits up to `wait` seconds (default 15, max 20): when done it returns 200 with the result, otherwise 202 with `Location: /api/public/v1/jobs/{job_id}`. The final status is succeeded, failed, cancelled or unknown.

> [!IMPORTANT]
> Needs an idempotency key (`Idempotency-Key`, 8–128 characters). Retrying with the same key never repeats the action.

> [!WARNING]
> A job that ends `unknown` may already have happened on X: never resend it with a new idempotency key.
