DROP-IN COMPATIBLE WITH LEADING AGENT FRAMEWORKS
Witness the exact difference between an unassisted bot request and StealthMark's clean token pipeline.
Autonomous agents require uninhibited data extraction across protected targets to make production-grade decisions.
| Metric | Standard | StealthMark |
|---|---|---|
| Success | 42.1% (Blocked) | 99.8% (Clean) |
| Tokens | 12,400 raw | 1,850 clean |
StealthMark is not a regex wrapper. It is dedicated headless cloud infrastructure built specifically to fool modern ML-based bot detectors.
Requests route through verified residential ISP subnets spanning 195+ countries. Datacenter IP ranges that trigger immediate Cloudflare 403 flags are never used for heavy targets.
We emulate the exact TLS handshake, cipher suites, HTTP/2 frames, and header ordering of authentic macOS Safari and Windows Chrome desktop browsers to pass passive network profiling.
Ephemeral isolated Chromium containers execute dynamic SPAs, wait for hydrated DOM elements, and simulate natural human cursor trajectories to pass Turnstile canvas checks.
Custom Mozilla Readability parser isolates core editorial blocks, keeping Markdown tables and images while destroying tracking pixels and navbars, saving up to 85% LLM tokens.
Embed StealthMark directly inside your agent system prompt, local MCP config, or Python automation workflow. No complex SDK installations required.
