Once you’ve deployed an app and invoked it, you can check its status. Invocations often take less time to complete than when run locally, since we run your app alongside its browser.

The API is available, and the CLI command is coming soon.

kernel invocation info <invocation_id>

App Invocation:
Invocation ID: 026d6dad-7a9d-4622-9c5a-a02ec6825889
Status: RUNNING # One of [QUEUED, RUNNING, SUCCEEDED, FAILED]

You can also access the invocation’s info by making a GET request to Kernel’s API:

const response = await fetch(`https://api.onkernel.com/invocations/${invocation_id}`, {
    headers: {
        'Authorization': `Bearer ${process.env.KERNEL_API_KEY}`,
        'Content-Type': 'application/json'
    }
});
const {
    id,
    app_name,
    action_name,
    payload,
    output,
    started_at,
    finished_at,
    status,
    status_reason } = await response.json();

Or, get the invocation’s info using Kernel’s SDK:

import { Kernel } from '@onkernel/sdk';

const {
    id,
    app_name,
    action_name,
    payload,
    output,
    started_at,
    finished_at,
    status,
    status_reason
} = await Kernel.invocations.get(invocation_id);

An invocation ends once its code execution finishes.

Once the invocation’s status reaches a terminal state (SUCCEEDED or FAILED), the same kernel invocation info command can be used to retrieve the replay.
