How this service works
A priced table of every common human-verification gate benchmarked against what it costs an agent to farm it in 2026: email, Turnstile, reCAPTCHA, hCaptcha, Arkose, proxies, SMS OTP, document KYC. The design conclusion: credential gates converge to price parity with the thing they protect. Prices as of mid-2026.
Output
The full text of a Tenjin article containing a structured pricing table benchmarking the cost for an AI agent to bypass common human-verification gates (email, Cloudflare Turnstile, reCAPTCHA, hCaptcha, Arkose Labs, proxies, SMS OTP, document KYC) as of mid-2026, along with the design conclusion that credential gates converge to price parity with the assets they protect.
Example use cases

AI agent red-team budget planning
“We're red-teaming our onboarding flow and need to estimate what budget a bad actor would need to automate bypass of our email verification, SMS OTP, and KYC gates — grab the Tenjin agent identity cost ladder article for the benchmarks.”
Research on credential gate economics
“I'm writing about the economics of human verification and the claim that credential gates converge to price parity with what they protect — can you retrieve the Tenjin Sybil cost ladder article so I can reference the 2026 price table?”

Choose this endpoint when you need a ready-made, benchmarked pricing table for human-verification gate bypass costs without building your own research — particularly useful for security teams designing anti-bot systems, researchers studying identity economics, or agents that need to reason about the cost-feasibility of Sybil attacks in 2026. Prefer this over raw search when you want a curated, structured analysis rather than scattered web results.
