title: Run a Task
subtitle: Execute a single browser automation with natural language
slug: running-automations/run-a-task
---

A **Task** is the simplest way to automate a browser action. 

You describe what you want in natural language, and Skyvern's AI navigates the web to complete it.

---

## Call `run_task`

A task has one required parameter and one commonly used optional parameter:

- **`prompt`** (required) — Natural language instructions describing what the AI should do
- **`url`** (optional) — The starting page for the automation

For additional parameters like engines, proxies, and extraction schemas, see [Task Parameters](/running-automations/task-parameters).

When you call `run_task`, Skyvern spins up a cloud browser, navigates to the URL, and executes your prompt. A typical task takes 30–90 seconds depending on complexity.

<CodeGroup>
```python Python
import os
import asyncio
from skyvern import Skyvern

async def main():
    client = Skyvern(api_key=os.getenv("SKYVERN_API_KEY"))

    result = await client.run_task(
        prompt="Get the title of the top post",
        url="https://news.ycombinator.com",
    )

    print(f"Run ID: {result.run_id}")
    print(f"Status: {result.status}")

asyncio.run(main())
```

```typescript TypeScript
import { SkyvernClient } from "@skyvern/client";

async function main() {
  const client = new SkyvernClient({
    apiKey: process.env.SKYVERN_API_KEY,
  });

  const result = await client.runTask({
    body: {
      prompt: "Get the title of the top post",
      url: "https://news.ycombinator.com",
    },
  });

  console.log(`Run ID: ${result.run_id}`);
  console.log(`Status: ${result.status}`);
}

main();
```

```bash cURL
curl -X POST "https://api.skyvern.com/v1/run/tasks" \
  -H "x-api-key: $SKYVERN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "Get the title of the top post",
    "url": "https://news.ycombinator.com"
  }'
```
</CodeGroup>

**Example response:**

```json
{
  "run_id": "tsk_v2_486305187432193504",
  "status": "queued",
  "output": null,
  "downloaded_files": null,
  "recording_url": null,
  "screenshot_urls": null,
  "failure_reason": null,
  "created_at": "2026-01-20T11:52:29.276851",
  "modified_at": "2026-01-20T11:52:29.484284",
  "app_url": "https://app.skyvern.com/runs/wr_486305187432193510",
  "run_type": "task_v2"
}
```

The response includes a `run_id`. Use this ID to check status, fetch results, and retrieve artifacts.

<Warning>
`run_task` returns immediately—the task is queued, not finished. Always poll or use webhooks to get results.
</Warning>

---

## Get results

The `run_task` call queues the task and returns immediately. 

Use the `run_id` to fetch results once the task reaches a terminal state.

| Status | Description |
|--------|-------------|
| `created` | Task initialized, not yet queued |
| `queued` | Waiting for an available browser |
| `running` | AI is navigating and executing |
| `completed` | Task finished successfully—check `output` for results |
| `failed` | Task encountered an error—check `failure_reason` and retry or adjust your prompt |
| `terminated` | Task was manually stopped |
| `timed_out` | Task exceeded time limit—increase `max_steps` or simplify the task |
| `canceled` | Task was canceled before starting |

You have three options for retrieving results:

### Option 1: Polling

Poll `get_run` until status is terminal (`completed`, `failed`, `terminated`, `timed_out`, or `canceled`).

<CodeGroup>
```python Python
run_id = result.run_id

while True:
    run = await client.get_run(run_id)

    if run.status in ["completed", "failed", "terminated", "timed_out", "canceled"]:
        break

    await asyncio.sleep(5)

print(f"Output: {run.output}")
```

```typescript TypeScript
const runId = result.run_id;

while (true) {
  const run = await client.getRun(runId);

  if (["completed", "failed", "terminated", "timed_out", "canceled"].includes(run.status)) {
    console.log(`Output: ${JSON.stringify(run.output)}`);
    break;
  }

  await new Promise((resolve) => setTimeout(resolve, 5000));
}
```

```bash cURL
#!/bin/bash
RUN_ID="YOUR_RUN_ID"

while true; do
  RESPONSE=$(curl -s -X GET "https://api.skyvern.com/v1/runs/$RUN_ID" \
    -H "x-api-key: $SKYVERN_API_KEY")

  STATUS=$(echo "$RESPONSE" | jq -r '.status')
  echo "Status: $STATUS"

  if [[ "$STATUS" == "completed" || "$STATUS" == "failed" || "$STATUS" == "terminated" || "$STATUS" == "timed_out" || "$STATUS" == "canceled" ]]; then
    echo "$RESPONSE" | jq '.output'
    break
  fi

  sleep 5
done
```
</CodeGroup>

<Warning>
Your polling loop must check **all** terminal states: `completed`, `failed`, `terminated`, `timed_out`, `canceled`. Missing one causes infinite loops.
</Warning>

### Option 2: Webhooks

Pass a `webhook_url` when creating the task. Skyvern sends a POST request to your URL when the task completes.

<CodeGroup>
```python Python
result = await client.run_task(
    prompt="Get the title of the top post",
    url="https://news.ycombinator.com",
    webhook_url="https://your-server.com/webhook",
)
```

```typescript TypeScript
const result = await client.runTask({
  body: {
    prompt: "Get the title of the top post",
    url: "https://news.ycombinator.com",
    webhook_url: "https://your-server.com/webhook",
  },
});
```

```bash cURL
curl -X POST "https://api.skyvern.com/v1/run/tasks" \
  -H "x-api-key: $SKYVERN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "Get the title of the top post",
    "url": "https://news.ycombinator.com",
    "webhook_url": "https://your-server.com/webhook"
  }'
```
</CodeGroup>

Skyvern sends a POST request with the full run data when the task completes or fails.

### Option 3: Wait for completion (Python only)

Block until the task finishes instead of polling manually.

```python Python
result = await client.run_task(
    prompt="Get the title of the top post",
    url="https://news.ycombinator.com",
    wait_for_completion=True,
)
print(result.output)
```

## Understand the response

The response from polling (`get_run`) and webhooks have slightly different structures. Both contain the core task data, but webhooks include additional metadata.

## Get artifacts

The run response contains high-level data like `output`, `recording_url`, and `screenshot_urls`. 

Every run also generates Artifacts, such as screenshots, reasoning logs, downloaded files, for observability. To get them, use `get_run_artifacts`.

<CodeGroup>
```python Python
artifacts = await client.get_run_artifacts(run_id)

for artifact in artifacts:
    print(f"{artifact.artifact_type}: {artifact.signed_url}")
```

```typescript TypeScript
const artifacts = await client.getRunArtifacts(runId);

for (const artifact of artifacts) {
  console.log(`${artifact.artifact_type}: ${artifact.signed_url}`);
}
```

```bash cURL
curl -X GET "https://api.skyvern.com/v1/runs/RUN_ID/artifacts" \
  -H "x-api-key: $SKYVERN_API_KEY"
```
</CodeGroup>

This returns a list of artifacts.
