Frequently Asked Questions

What builders need to know before monetizing with Zerocost.

You add the SDK, choose the placements you want, and Zerocost sells relevant ad demand and optional anonymized data products behind the scenes. You earn when ads run or approved data products sell.

Any startup, SaaS product, AI app, website, or developer tool can join. The best fit is a product with engaged users and a free or low-cost usage tier that needs a revenue layer.

Yes. You control placement format, position, theme, and app profile details used for contextual matching. Zerocost reviews creatives and avoids sensitive or misleading ad categories.

Data products require consent and are anonymized before sale. Buyers receive aggregated, privacy-safe interaction patterns, not personal user profiles or raw private information.

Your dashboard tracks earnings from ads and data products. Available balances can be withdrawn from the payouts area once revenue has settled.
