The payment stack for AI agents, assistants, and workflows.

Policy engine matching

Signets helps teams add payments to AI workflows without taking on card handling, money-movement operations, and reconciliation infrastructure themselves.

Let your agents pay and get paid. Securely.

Give your agents the ability to check out, pay vendors, collect funds, or trigger billing flows without stitching together the payment stack on your own.

From request to settlement.

Policy-aware orchestration

An AI agent, assistant, or workflow submits a payment request. Signets evaluates purpose, amount, merchant, and approval rules before money moves.

Rail selection by use case

Use cards for checkout, virtual accounts for collections, bank rails for invoices, and stablecoins for internet-native payments without separate systems for each one.

Real-time authorization

Merchant restrictions, budgets, approval workflows, and transaction checks are enforced in the payment path, not just in prompts.

Reconciliation built in

Every transaction is recorded with the workflow, intent, and outcome that caused it, so finance and ops can work from the same source of truth.

PLATFORM

One integration.
Every payment flow.

Step 01

Set the rules

Decide what your agents can spend on, where, how much, and how often. Before they touch a dollar.

Step 02

Issue the primitives

Cards, wallets, and accounts created on the fly. Each agent gets exactly the payment instrument it needs.

Step 03

Agents transact autonomously

Agents pay vendors, receive payments, and complete purchases. Within policy, with full ledger tracking.

Use Cases

Built for how agents actually move money.

Why Teams Start With Signets.

Less payments complexity

Add payments to AI products without building your own card, controls, and reconciliation stack from scratch.

Controls in the transaction path

Spending rules, merchant locks, and approval workflows live in the payment layer, not only in agent logic.

Reconciliation from day one

Payment events arrive with the context product, finance, and ops teams need to review what happened.
