- **`@emitkit/js` 3** (`npm install @emitkit/js@next`). Typed requests and
  responses; `ask()` sends a question and waits for the answer from someone's
  phone; `events.get`, `events.list`, `events.cancel`, `channels.list`,
  `identities.delete` and `me`; `verifyCallback()` for
  [callbacks](/concepts/questions#callbacks); one `EmitKitError` with the
  API's `code`; safe retries with an automatic idempotency key. No
  dependencies. See the [SDK docs](/sdk).
- **The CLI** (preview, from its [GitHub release](https://github.com/emitkithq/sdks/releases); `npx @emitkit/cli@next` once it's on npm). `emitkit send`, `ask` (waits, with
  exit codes for scripts), `events`, `tail`, `channels`, `identify`, with
  `--json` for agents. See [CLI](/cli).
