PayClaw solves the bot detection problem for AI agents trying to shop online. It provides two tools: Badge declares your agent as an authorized actor using the Universal Commerce Protocol, letting it handshake with merchants like Shopify, Target, and Walmart without getting blocked. Spend issues single-use virtual Visa cards for checkout, human-approved via device flow, that self-destruct after use. The server works immediately with no API key for basic Badge functionality. Add credentials to unlock cryptographic verification and card issuance. Useful when your agent needs to browse or buy from UCP-compliant merchants without manual intervention or exposing your real payment details.
