Paybox

Paybox lets a person connect their wallets, cards, and secrets once, then authorize an AI agent to pay, sign, and authenticate on their behalf — within limits they set, behind a passkey for anything sensitive.

Agents never receive raw credentials. They get scoped outputs:

• Cards → a one-time virtual card
• Wallets → a signed transaction (the private key never leaves MoonX MPC)
• Secrets → a short-lived token

You stay in control: above-threshold operations pause for a passkey approval, every operation is an audit event, and any agent client can be revoked at any time.

Where to go next

• Getting started — vault a credential and issue your first agent client.
• Credentials & agents — the core model: credentials, clients, grants, approval modes.
• Request lifecycle — the submit → approve → poll pattern every operation follows.
• MCP connector — plug Paybox into Grok, Claude.ai, or any MCP-speaking agent with one URL.
• MCP tools — the tools an agent calls: pay, sign, reveal secrets, swap, pay x402 services, fund a wallet.
• OAuth 2.1 — how third-party apps connect via OAuth + PKCE.
• API & endpoints · SDK & CLI — the public surface, and the typed Node SDK + paybox CLI over it.
