## Props

| Prop | Type | Required | Description |
|---|---|---|---|
| `accounts` | `string[]` | Yes | The connected accounts to publish to. List Accounts action can be used to discover account IDs. Options are loaded from the connected account. |
| `text` | `string` | No | The post body. Optional when the post is media-only on platforms that allow it. |
| `media` | `string[]` | No | Media attachments. Each item is a JSON object with kind (image or video) and exactly one of url or mediaId, plus an optional altText. Example: {"kind":"image","url":"https://cdn.example.com/launch.jpg","altText":"Launch banner"} |
| `firstComment` | `string` | No | Posted as the first comment under the published post, where the platform supports it. |
| `publishNow` | `boolean` | No | Publish immediately. Turn off to schedule for a future time. |
| `scheduledAt` | `string` | No | When to publish the post (ISO 8601). Required when Publish Now is off. |
| `profileId` | `string` | No | UUID of a letmepost profile. Example: 550e8400-e29b-41d4-a716-446655440000. Discover valid values from the profileId field on posts returned by List Posts or Get Post. |
| `idempotencyKey` | `string` | No | Reusing the same key never publishes twice, which makes retries safe. |
