DETECTION & ANTI-BOT
Yes, here's exactly what sites look for, and how this web scraper API gets past it.
Yes. Sites look for patterns that don't match normal human browsing, consistent request timing, missing or inconsistent HTTP headers, no JavaScript execution, repeated requests from the same IP, and browser fingerprinting that flags headless-browser signatures.
Human browsing is irregular, pauses to read, click around, come back later. A script hitting the same site every 2 seconds around the clock is an obvious signal, and rate-based detection is one of the simplest, most widely deployed defenses.
Every browser sends a set of headers (user agent, accept-language, and more) in a consistent, recognizable pattern. Scripts that send minimal or inconsistent headers, or that don't execute JavaScript at all, stand out immediately to any site checking for it.
Datacenter IP ranges are widely known and pre-flagged by most anti-bot systems, since legitimate consumer traffic rarely originates from cloud hosting providers. Residential IPs, which route through real ISP connections, don't carry that same red flag.
Beyond basic checks, dedicated systems, Cloudflare, DataDome, Akamai Bot Manager, Imperva Incapsula, PerimeterX, and Kasada, combine multiple signals (timing, fingerprinting, JavaScript challenges, behavioral analysis) into a single detection layer. These are the systems this API bypasses automatically on every plan, at no extra per-request cost.
