# List Browserbase agent run messages

> Read chronological assistant and tool messages from a run.

`browserbase.listAgentRunMessages` reads chronological assistant and tool messages from a run. Inputs accept literal values or compatible signals. An optional second argument `{ account }` selects a named Browserbase binding.

## Example

```ts theme={null}
import { automation, onInvocation } from "automate.ax"
import { browserbase } from "automate.ax/browserbase"

export default automation("List Browserbase agent run messages", () => {
  onInvocation()
  browserbase.listAgentRunMessages({ runId: "run-id", limit: 100 })
})
```

## Inputs

| Input   | Type      | Required | Default          | Description                                 |
| ------- | --------- | -------- | ---------------- | ------------------------------------------- |
| `runId` | `string`  | Yes      | —                | Browserbase run ID.                         |
| `since` | `string`  | No       | Beginning        | Cursor from `nextSince`.                    |
| `limit` | `number`  | No       | Provider default | 1 through 100.                              |
| `all`   | `boolean` | No       | `false`          | Ask Browserbase for all available messages. |

## Output

Returns AI SDK-compatible messages and nullable `nextSince`.

Pass `nextSince` as `since` for incremental polling.
