## Run A Task
- [Quickstart](/getting-started/quickstart) to run a task.
- [Run Task API](/api-reference/api-reference/agent/run-task)
Every feature in this page is enabled through API & SDK. Some features are enabled through [Skyvern's Discover page](https://app.skyvern.com/discover) as well.
### [Engine](/api-reference/api-reference/agent/run-task#request.body.engine)
Parameter: `engine`
This parameter defines the engine that powers the agent task.
- `skyvern-2.0`: this is the default engine. It's the latest Skyvern agent that performs really well with complex and multi-step tasks. It scores **state of the art** 85.85% on the [WebVoyager benchmark](https://blog.skyvern.com/skyvern-2-0-state-of-the-art-web-navigation-with-85-8-on-webvoyager-eval/).
- `skyvern-1.0`: performs really well for tasks with a simple goal, like filling a form, or searching for information on Google.
- `openai-cua`: uses OpenAI's CUA model.
- `anthropic-cua`: uses Anthropic's Claude Sonnet 3.7 model with the computer use tool.
### [Data Extraction Schema](/api-reference/api-reference/agent/run-task#request.body.data_extraction_schema)
Parameter: `data_extraction_schema`
The schema for data to be extracted from the webpage. If you're looking for consistent data schema being returned by the agent, it's highly recommended to use https://json-schema.org/.
### [Send Webhook](/api-reference/api-reference/agent/run-task#request.body.webhook_url)
Parameter: `webhook_url`
You can set the `webhook_url` to receive the update when the task is done. Check [Webhooks FAQ](/running-tasks/webhooks-faq) for more details.
### [Max Steps](/api-reference/api-reference/agent/run-task#request.body.max_steps)
Parameter: `max_steps`
Maximum number of steps the task can take. Task will fail if it exceeds this number. Caution: you are charged per step, so set this number to a reasonable value. Contact sales@skyvern.com for custom pricing.
### [Error Code Mapping](/api-reference/api-reference/agent/run-task#request.body.error_code_mapping)
Parameter: `error_code_mapping`
Custom mapping of error codes to error messages if Skyvern encounters an error.
For example:
```json
[
{"login_failed": "The login credentials are incorrect or the account is locked"},
{"maintenance_mode": "The website is down for maintenance"},
]
```
With this mapping, if Skyvern encounters a login failure, the task output will show `{"error": "login_failed"}`, which makes it easy to codify error handling.
### [Proxy Location](/api-reference/api-reference/agent/run-task#request.body.proxy_location)
Parameter: `proxy_location`
Some websites block requests from certain countries. You can set a proxy location to route the browser traffic through.
### 2FA Support (TOTP)
- [totp_identifier](/api-reference/api-reference/agent/run-task#request.body.totp_identifier): Skyvern can receive the TOTP code and use this identifier to identify the code for authentication.
- [totp_url](/api-reference/api-reference/agent/run-task#request.body.totp_url): Skyvern makes a request to this URL to fetch the TOTP code when needed.
More details can be found in the [TOTP section](/credentials/totp).
### [Run Task In A Persistent Browser Session](/api-reference/api-reference/agent/run-task#request.body.browser_session_id)
Parameter: `browser_session_id`
You can set a browser session for a task. Having a browser session persist the real-time state of the browser, so that the next run can continue from where the previous run left off.
See the [Browser Sessions](/browser-sessions/introduction) section to see how to create a browser session.
