CPA-only: the only honest pricing for agent ads

Display advertising's original sin was selling impressions — a unit of value defined as "the ad was technically on screen." The entire fraud industry that followed (bot farms, pixel stuffing, viewability arbitrage) exists because impressions are cheap to fake and expensive to verify.

Now put that model inside the agent economy, where the "user" is often a script in a loop. An agent can generate a million tool calls overnight. If anyone pays per impression in this world, they are funding a money printer for fraudsters.

So we simply don't sell that

Lulu Ads charges on conversions (and clicks that survive verification). The chain looks like this:

1. A slot is filled — recorded, but worth $0.
2. A click carries a signed token — still worth $0 until…
3. …the token is redeemed in a real browser session, and
4. the conversion is audited by the affiliate network that pays out.

A bot hammering our slot endpoint costs us bandwidth and earns everyone exactly nothing. Impression fraud attacks a price we don't charge. That's not a fraud filter — it's fraud irrelevance, designed into the pricing itself.

What publishers should take from this

If an agent-ads network offers you CPM revenue, ask who's counting the impressions and who profits when the count is wrong. The honest math is slower to compound but impossible to fake: unrendered = unpaid, and 70% of every real conversion goes to you.
