How do I make sure that my script waits enough for all the element to appear on the page?

AgentQL SDK provides the wait_for_page_ready_state() API to determine page readiness. This method waits for the page to be in a ready state and all the necessary network requests to be completed. However, there are some cases where the page might not be ready even after the method returns. This could be due to the dynamic nature of the page. In such cases, you can use the page.wait_for_timeout function to add a additional delay to your script. const { wrap } = require("agentql"); const { chromium } = require("playwright"); const QUERY = ` { related_videos[] { video_name video_rating } } `; async function main() { const browser = await chromium.launch({headless: false}); const page = await wrap(await browser.newPage()); await page.goto("https://www.youtube.com/watch?v=1ZvYrAaJOH4"); await page.waitForPageReadyState(); await page.waitForTimeout(5000); const response = await page.queryData(QUERY); console.log(`Related videos: \n${JSON.stringify(response, null, 2)}`); await browser.close(); } main();

While writing AgentQL Script, how do I ensure the web page is loaded entirely?

It's currently not possible to programmatically define when a page has finished loading—a script may bring new information on to the page, as in the case of infinite scrolling or lazy loading images. You can use Playwright API to scroll the page up and down to load the more content. const { wrap } = require("agentql"); const { chromium } = require("playwright"); const QUERY = ` { comments[] } `; async function main() { const browser = await chromium.launch({headless: false}); const page = await wrap(await browser.newPage()); await page.goto("https://www.youtube.com/watch?v=1ZvYrAaJOH4"); for (let i = 0; i < 3; i++) { await page.mouse.wheel(delta_x=0, delta_y=1000); await page.waitForPageReadyState(); } await page.mouse.wheel(delta_x=0, delta_y=-3000); const response = await page.queryData(QUERY); console.log(`Video comments: \n${JSON.stringify(response, null, 2)}`); await browser.close(); } main();

How do I specify the format of data returned by AgentQL?

Since the release of 0.4.7 version, AgentQL supports providing context to query in the following way: { products[] { price(Format the output as a numerical value only, no dollar sign) name(Format the output with the following prefix: amazon_) } } As you can see, by providing formatting instructions as a context into the query, you could instruct AgentQL to return the expected data format.
