How MarketPulse handles sites that block automated requests

Some sites — Amazon is the most common example — actively block plain, unauthenticated requests. When that happens to a tracked competitor link, MarketPulse doesn’t just fail and give up: it automatically retries the check through a real, stealth-configured browser session instead, so tracking keeps working on listings that would otherwise silently stop updating.

What “stealth-configured” actually means

The fallback runs a real browser engine configured to look and behave like an ordinary visitor — realistic headers, browser fingerprint characteristics, and request timing — rather than the easily-detected signature of a bare HTTP client. This is browser-level fingerprint handling built directly into MarketPulse’s own tracking engine, not a third-party anti-detect service.

A rotating residential proxy for the hardest cases

For sites that block even a well-configured browser session, MarketPulse can additionally route the request through a proxy service, so the request doesn’t come from a pattern of IPs a site has already learned to block.

Set expectations honestly

No anti-bot handling is bulletproof, and a small number of sites remain genuinely difficult to track reliably no matter the approach — MarketPulse would rather tell you a specific link is having trouble than silently show stale data. If a link’s checks start failing consistently, you’ll see that reflected in its status rather than a price that quietly stops updating without explanation.
