Scoped virtual cards
Each subscription gets its own card with an authoritative spending policy. A vendor overcharging gets declined at authorization time — your real card is never in play.

Every dollar sits behind a scoped virtual card. Every spend raise and account change waits for your approval.
Billzo does the browser work, the payments, and the account management — driven from the MCP client you already use. No new chat app. No credentials pasted into a prompt — scoped cards, vaulted secrets, and a control panel for the moments that need a human.
Two flows, one set of rails
Point Billzo at a self-serve vendor and it runs the whole flow — pausing only when a real human decision is needed.
Billzo provisions an email alias, navigates the signup flow, generates and vaults strong credentials, and completes email and phone verification. It issues a scoped virtual card and enters billing — returning a tidy subscription record. Your inbox and your real card number never touch the vendor.
Already paying for something? Billzo takes over the account on the same rails: connect once, swap in a scoped card, and transfer the root of trust — new MFA, rotated password, platform email — in a careful, lockout-averse order. Nothing happens until you consent to exactly what it will do.
The trust model
Handing an agent your billing is an authority problem, not a chat problem. Limits and approvals are enforced in code, not written in a policy PDF.
Each subscription gets its own card with an authoritative spending policy. A vendor overcharging gets declined at authorization time — your real card is never in play.
Destructive steps — spend raises, migrations, policy changes — halt until you approve the exact details, echoed back verbatim. Decisions are idempotent, attributed, and audited, with a confirmation sent to you.
Passwords and TOTP seeds live in a per-tenant encrypted vault (AES-256-GCM, wrapped keys). They flow transiently to the browser session and are never written to logs, checkpoints, or your chat transcript.
Persisted checkpoints use typed schemas that cannot represent card numbers, passwords, or one-time codes — secrets are excluded by construction, and every log line passes through a redacting logger.
Connect
Everything runs through the Model Context Protocol. Point your MCP-capable client — Claude Code, Cursor, Claude Desktop, or your own — at the Billzo endpoint and authenticate once through AuthKit. From there your agent can initiate signups and migrations, review approvals, and manage subscriptions — all scoped to your organization.
