8. `public static String generateSign(String secretKey, String data) {`
10. `Mac mac = Mac.getInstance(ALGORITHM);`

11. `public BaiduSearchClient(String apiKey, String secretKey) {`
13. `this.secretKey = secretKey;`
16. `public String search(String query, int page, int size) throws Exception {`
17. `String timestamp = String.valueOf(System.currentTimeMillis());`
18. `String signData = apiKey + query + page + size + timestamp;`
19. `String sign = AuthUtil.generateSign(secretKey, signData);`
21. `String url = BASE_URL + "?q=" + URLEncoder.encode(query, "UTF-8")`
28. `try (CloseableHttpClient client = HttpClients.createDefault()) {`
29. `HttpGet request = new HttpGet(url);`
30. `return client.execute(request, httpResponse -> `
31. `EntityUtils.toString(httpResponse.getEntity()));`

HTTP 200

You just saw the output.

That was one page. A key runs the same call across every URL on baidu.com, with browser rendering, proxies, and concurrency. Sign up and a free balance lands on your account. No card required to test.

The same call, in code.

The keyless call above returns markdown. These examples add a key, so you get browser rendering, proxies, and concurrency on baidu.com.

baidu-scraper.ts

import { SpiderBrowser } from "spider-browser";

const spider = new SpiderBrowser({
  apiKey: process.env.SPIDER_API_KEY!,
});

await spider.connect();
const page = spider.page!;
await page.goto("https://www.baidu.com/s?wd=web+scraping");

// No selectors, no schema. Spider reads the page and names the fields.
const data = await page.scrape();

console.log(data);
await spider.close();

import { SpiderBrowser } from "spider-browser";

const spider = new SpiderBrowser({
  apiKey: process.env.SPIDER_API_KEY!,
  stealth: 2,
});

await spider.connect();
const page = spider.page!;
await page.goto("https://www.baidu.com/s?wd=web+scraping");
await page.content();

const data = await page.evaluate(`(() => {
  const results = [];
  document.querySelectorAll(".result.c-container").forEach((el, i) => {
    const title = el.querySelector("h3 a")?.textContent?.trim();
    const url = el.querySelector("h3 a")?.getAttribute("href");
    const snippet = el.querySelector("[class*='c-abstract'], h3 ~ div, h3 ~ span")?.textContent?.trim();
    if (title) results.push({ position: i + 1, title, url, snippet });
  });
  return JSON.stringify({ total: results.length, results: results.slice(0, 10) });
})()`);

console.log(JSON.parse(data));
await spider.close();

Spider names these from the page. The capture above came back as markdown; the same call with return_format: "json" returns them as keys.

What baidu.com costs to scrape.

The capture above cost $0.000462 to fetch. Pricing is $1 per GB of pre-transformation bandwidth plus $0.001 per CPU minute, so a page like this one lands at a fraction of a cent. Failed requests are billed at $0.
