# PayBox

PayBox is a non-custodial wallet for AI agents. Users connect wallets, cards, and secrets, then grant agents scoped access to pay, sign, swap, and authenticate.

## Connection

Connect an MCP client to https://api.paybox.sh/mcp. The client uses OAuth 2.1 with PKCE. A user can also issue a personal API key in the PayBox app and send it as a Bearer token.

PayBox returns scoped outputs such as payment tokens, signatures, transaction hashes, and short-lived secret tokens. It does not return raw wallet keys, card numbers, or passwords.
