Build a Web Scraper with Vibe Coding
Web scrapers are tedious to build traditionally — Puppeteer configs, headless browsers, proxy rotation, anti-bot detection. With vibe coding + YepAPI, you skip all of that. Describe what data you want to extract, your AI tool writes the code, and YepAPI's Web Scraping API handles the browser rendering, JavaScript execution, and proxy infrastructure.
APIs you need for a web scraper
How to vibe code a web scraper
Define what to scrape
Be specific: "Extract product names, prices, and availability from Amazon search results for a given keyword." The more precise your data requirements, the better the scraper.
Build the scraper
Prompt: "Build a scraper that takes a URL, calls YepAPI's Web Scraping API to get the page content, and extracts product data into a structured JSON array." Drop llms.txt so the AI knows the exact API parameters.
Add scheduling
"Run this scraper every hour using a cron job. Store results in a database and send an alert when prices change." Your AI tool can set up scheduled jobs with node-cron or similar libraries.
Build the UI
"Create a dashboard that shows scraped data in a table with filters, charts for price trends, and a button to trigger manual scrapes." Pair the scraper with a frontend for a complete monitoring tool.
What to build with Web Scraper + YepAPI
“Build a price monitoring tool that scrapes 20 product URLs daily, stores prices in a database, and shows price history charts with email alerts for drops.”
“Create a content aggregator that scrapes tech news sites, extracts article titles and summaries using AI, and displays them in a clean feed.”
“Build a lead generation scraper that extracts business contact info from directory websites and exports to CSV.”

Frequently asked questions
Generally yes for publicly available data, but always check the website's robots.txt and terms of service. Don't scrape personal data, copyrighted content, or behind-login content without permission. YepAPI's API handles rate limiting and respectful crawling.
YepAPI handles browser rendering, JavaScript execution, proxy rotation, CAPTCHA solving, and anti-bot detection. With Puppeteer, you manage all of that yourself. The API approach is faster to build, cheaper to run, and more reliable at scale.
YepAPI's stealth scraping mode handles most anti-bot measures automatically. For particularly aggressive sites, use the JavaScript rendering option and rotate through different browser profiles. The API abstracts away the complexity.
