Everything you need for price intelligence
Parallel Batch Crawling
Submit thousands of product URLs in one request. Spider fetches them concurrently and returns structured price data in seconds, not hours.
Structured JSON Extraction
Pull product names, prices, SKUs, availability, and images as clean JSON. Use CSS selectors or AI extraction to target the exact data fields you need.
Webhook Price Alerts
Get notified the moment a price drops, a product goes out of stock, or a competitor changes their listing. Real-time events pushed to your endpoint.
199+ Country Proxies
See region-specific pricing from any market. Access localized storefronts with residential proxies so you get the exact price your customers see.
99.9% Anti-Bot Bypass
E-commerce sites run aggressive bot detection. Spider rotates fingerprints, solves challenges, and renders JavaScript so you never miss a price update.
No Credit Multipliers
Same flat rate whether a site is easy or heavily protected. Unlike competitors who charge 5-75x more for bot-protected pages, Spider is always predictable.
Extract prices in a few lines
Use CSS selectors to pull exactly the fields you care about. Spider handles JavaScript rendering, proxy rotation, and anti-bot challenges behind the scenes.
