ChatGPT Agent, Perplexity Buy, and Copilot Shopping are purchasing on behalf of real people — right now, at your Shopify store. Your fraud tools can't tell them from bots. Vouch can.
Vouch intercepts every agent session before checkout renders — verifying identity, authorization, and intent before your payment processor ever sees the request.

FAQ
Common questions.
No. Vouch installs from the Shopify App Store in two clicks — no API keys, no code changes, no engineering team required. If you can install any Shopify app, you can install Vouch.
Sessions with a score between 40 and 69 land in REVIEW rather than BLOCK — they proceed with logging. You control the thresholds in your dashboard. A cryptographic failure is the only hard block, and those are unambiguously malicious sessions.
No. Vouch sits upstream of your payment processor — it verifies the agent session before Stripe ever sees the request. Your existing fraud tools still run on the transaction. Vouch stops the false decline from happening in the first place, before the payment layer.
OpenAI (ChatGPT Agent), Meta, Anthropic, Google, Microsoft (Copilot Shopping), and Perplexity (Instant Buy) — six operators covering 99% of all commercial AI agent traffic. Unknown operators are blocked by default until registered.
Median 25 milliseconds. 99th percentile under 80 milliseconds. The checkout page load time is not meaningfully affected. Verification completes before the payment form renders.
Any transaction that receives a PASS verdict from Vouch on the Scale plan is covered by Vouch's chargeback indemnification. If a verified agent session results in a dispute, Vouch covers the chargeback cost. This is our commitment that the scoring model works.
