Your agent runs 24/7.
Now so does your control over it.

Set limits once. Attestify checks every payment request before your agent spends a dollar — enforced server-side, before any API call, before any money moves.

Why a shared card is the wrong tool

Card rails were built for humans. Agents are a different shape of spending.
