Instance Method Details

#get_question(url, opts = {}) ⇒ String

Get an answer to a question about a given web page Returns the answer in plain text. Proxies and Chromium JavaScript rendering are used for page retrieval and processing, then the answer is extracted using an LLM model.

Parameters:

  • url (String)

    URL of the target page.

  • opts (Hash) (defaults to: {})

    the optional parameters

Options Hash (opts):

  • :question (String)

    Question or instructions to ask the LLM model about the target page.

  • :context_limit (Integer)

    Maximum number of tokens to use as context for the LLM model (4000 by default). (default to 4000)

  • :response_tokens (Integer)

    Maximum number of tokens to return in the LLM model response. The total context size (context_limit) includes the question, the target page content and the response, so this parameter reserves tokens for the response (see also on_context_limit). (default to 100)

  • :on_context_limit (String)

    What to do if the context_limit parameter is exceeded (truncate by default). The context is exceeded when the target page content is too long. (default to ‘error’)

  • :headers (Hash<String, String>)

    HTTP headers to pass to the target page. Can be specified either via a nested query parameter (…&amp;headers&#x3D;value1&amp;headers&#x3D;&#x3D;value2) or as a JSON encoded object (…&amp;headers&#x3D;&quot;value1&quot;, &quot;Another&quot;: &quot;value2&quot;).

  • :timeout (Integer)

    Maximum web page retrieval time in ms. Increase it in case of timeout errors (10000 by default, maximum is 30000). (default to 10000)

  • :js (Boolean)

    Execute on-page JavaScript using a headless browser (true by default). (default to true)

  • :js_timeout (Integer)

    Maximum JavaScript rendering time in ms. Increase it in case if you see a loading indicator instead of data on the target page. (default to 2000)

  • :proxy (String)

    Type of proxy, use residential proxies if your site restricts traffic from datacenters (datacenter by default). Note that residential proxy requests are more expensive than datacenter, see the pricing page for details. (default to ‘datacenter’)

  • :country (String)

    Country of the proxy to use (US by default). Only available on Startup and Custom plans. (default to ‘us’)

  • :device (String)

    Type of device emulation. (default to ‘desktop’)

  • :error_on_404 (Boolean)

    Return error on 404 HTTP status on the target page (false by default). (default to false)

  • :error_on_redirect (Boolean)

    Return error on redirect on the target page (false by default). (default to false)

  • :js_script (String)

    Custom JavaScript code to execute on the target page.

Returns:

  • (String)
