Ad Spend & Growth Ops Agents
Let agents run growth experiments and manage ad accounts with strict budgets, approval gates for scale-ups, and clean attribution.
The Problem
Ad platforms happily charge whatever budget you set. If an agent makes a bad call—or is manipulated—it can burn cash quickly. Shared cards also make it hard to attribute spend by channel or campaign.
The Solution
Use per-channel dedicated cards with hard caps, require approval to raise budgets, and reconcile every charge to an intent and campaign metadata.
Key Features
Per-channel cards
One card for Google, one for Meta, one for tools. Attribution becomes automatic.
Hard budget caps
Set daily/weekly caps enforced at the card boundary—not just in the ad UI.
Approval gates for scale-ups
Let agents iterate under $X, but require a human to raise budgets or add new merchants.
Campaign-linked evidence
Attach campaign IDs and intent metadata so finance can trace every charge.
How It Works
Agent proposes experiment
Agent drafts a campaign plan and requests a small test budget.
Test budget approved
Policy auto-approves within a small threshold; otherwise it escalates.
Spend isolated by channel
Agent pays using a dedicated channel card with a strict cap.
Reconcile and report
Charges are tied to campaign metadata and summarized for finance and growth.
Code Example
// Create a dedicated card for Meta ads
const metaCard = await signets.cards.create({
agent_id: "growth-agent",
spending_limit: 10000, // $100.00 weekly test budget
merchant_lock: "facebook.com",
recurring: true,
metadata: { channel: "meta" },
});
// Escalate before raising budgets
const intent = await signets.intents.create({
purpose: "Increase Meta spend for winning campaign",
expectedAmount: 50000,
expectedMerchant: "facebook.com",
});Ready to get started?
