E-Commerce Intelligence

Your competitor dropped their price 20 minutes ago

You found out from a customer. Spider monitors competitor pricing across thousands of product pages and alerts you in real time so you react before your customers notice.

Why price tracking bills are unpredictable

Other providers

  • Credit multipliers: 5-75x for bot-protected e-commerce sites
  • Monthly bill swings from $800 to $4,200 based on site difficulty
  • Credits expire monthly regardless of usage
  • Managing your own proxy infrastructure is a full-time job

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.
