Extension Metadata

About this extension
Veyrun is a buyer agent for x402-enabled sites. It detects payment-required responses, lets you confirm once, completes the payment, unlocks access, and stores receipts locally. No accounts. No checkout forms.

What Veyrun is
Some sites no longer show a checkout. They respond with Payment Required. Veyrun is how you answer. It detects x402 (HTTP 402) payment requests, prepares the transaction, and lets you approve in one step. It then retries the request and unlocks access automatically. This is not a faster checkout. This is checkout removed.

What Veyrun does
Veyrun detects x402 payment-required responses, shows the requested amount, recipient, and purpose, uses an in-extension agent wallet to complete payment, retries the request to unlock access, and stores receipts locally with optional JSON export.

Built for
Paywalled articles and premium content, micropaid APIs and endpoints, agent-ready commerce experiments, and developers or power users exploring x402 flows.

Wallet and receipts
Each installation has its own agent wallet. Balance and network are visible in the extension. Receipts are stored locally on your device and can be exported as JSON. No account creation is required.

Standards
Veyrun is built for emerging agentic commerce standards, including x402 and agent-to-agent payment flows.

Privacy
Wallet data and receipts are stored locally. No analytics trackers. No data is sold or shared. No remote account required.

Veyrun is experimental and intended for early adopters exploring agentic commerce and x402-enabled sites.
