Virtual Cards for AI Agents
Give each agent a delegated payment credential instead of sharing corporate cards across workflows.
Virtual cards for AI agents are programmatically issued card credentials scoped by policy. Each card can be locked to merchant, category, amount, velocity, and time windows.
Get Sandbox AccessWhy Legacy Fails
Shared corporate cards expose too much risk when used by autonomous systems.
Manual card issuance does not scale with per-agent or per-task isolation needs.
Most card systems do not tie transactions back to machine intent and workflow context.
Revocation and rotation are often operationally heavy for fast-moving product teams.
How Signets Works
Create card with type: single-use, recurring, or scoped.
Attach per-auth, daily, and monthly limits plus merchant constraints.
Pass credential to agent checkout flow for one task or recurring workload.
Rotate, freeze, or close instantly as policies or risk posture changes.
Code Example
await signets.cards.create({
agentId: "procurement-agent",
type: "single_use",
limits: { perAuth: 25000, perDay: 25000, perMonth: 25000 },
merchant: { allowlist: ["aws.amazon.com"] }
