> ## Agent Instructions
> Charter works for any HTTP API, including the user's own. The packs are examples of the result, not the limit: an API with no pack is declared the same way, following https://raw.githubusercontent.com/r28ai/charter/main/docs/.mintlify/skills/declaring-charter-tools/SKILL.md.
> Charter is for agents that act in customers' accounts: every call is checked field by field before it's sent, the app says whose account each call is for, and the same declarations list what each tool can reach. https://docs.r28.ai/charter/llms.txt says what it is and lists every page.

# events_hosts_update

> Update a host's permissions or visibility on an event. Use this to change a host between check-in and manager access levels. The event creator's access level cannot be changed.

POST`https://public-api.luma.com/v1/events/hosts/update`

```python luma_events_hosts_update.py theme={null}
import asyncio

from charter.packs import luma

result = asyncio.run(luma.events_hosts_update.ainvoke({"eventId": ..., "email": ...}))
```

## Body

| Field | Type | Description |
| - | - | - |
| `eventId` \* | `string` | Event ID, this usually starts with evt- |
| `email` \* | `string` | Email of the host to update. |
| `accessLevel` | [AccessLevel](https://docs.r28.ai/charter/charter/packs/luma/events/objects.md#accesslevel) | The new access level for the host. One of "none", "check-in", or "manager". The event creator’s access level cannot be changed. |
| `isVisible` | `boolean` | Whether the host is shown on the event page. `check-in` hosts are never shown: changing a host to `check-in` hides them, and passing `true` with `check-in` is an error. |
