Overview

The node "Nerve Agent" provides an interface to interact with the Nerve Agent AI system, which supports multiple resources including Browser Automation. Specifically, for the Browser Automation resource and the Extract Content operation, the node automates web interactions such as navigating to a URL, performing a series of browser actions (clicking elements, typing text, extracting text, taking screenshots), and extracting content from web pages.

This is beneficial in scenarios where users want to programmatically scrape data, automate form submissions, or capture webpage screenshots without manual intervention. For example, it can be used to extract product details from e-commerce sites, automate login flows, or gather news headlines from various sources.

    • Incorrect CSS selectors: Verify selectors match elements on the page; otherwise, actions like click or extract will fail.
    • Missing or invalid API credentials: Confirm that the API key credential is properly configured.
    • Network restrictions or firewall blocking access to target websites or the Nerve Agent API.

  • Error messages:
