Two Different Philosophies of Pricing
TollBit and ProRata are both AI content marketplaces. They differ fundamentally on the pricing philosophy. TollBit prices per-fetch with publisher-controlled rates: every URL fetch generates a fixed payment to the publisher, regardless of whether the resulting AI answer cited the source meaningfully. ProRata prices per-citation with answer-level attribution: payment is decomposed across the sources that contributed to the answer, proportional to each source's contribution.
The choice between them is not just operational. It is a choice about whether your content earns more under flat per-fetch pricing or under contribution-weighted attribution. For most publishers, the answer depends on content quality and substitutability.

What TollBit Does Well
TollBit's per-fetch model is operationally simple and publisher-friendly. The publisher sets a price, the AI bot pays it, the marketplace transfers the revenue. There is no ambiguity about how a citation contribution is calculated. Revenue tracks fetch volume linearly, which makes it predictable and easy to forecast.
For commoditised content (broadly-fetchable inventory like general news, B2B guides, encyclopedic content), per-fetch pricing produces more total revenue than ProRata's attribution model. The reason is that commoditised content has low per-citation contribution scores under attribution, which means ProRata pays less per citation than TollBit pays per fetch for the same content.
What ProRata Does Well
ProRata's attribution methodology rewards content that genuinely contributes to AI answers. Primary research, exclusive financial data, premium news, and specialty content typically score higher per-citation under ProRata's attribution than they earn per-fetch under TollBit. The high end of the ProRata distribution can pay 3-5x what comparable TollBit per-fetch pricing produces for the same inventory.
ProRata also operates Gist.ai as a consumer-facing AI search product that demonstrates the attribution methodology in production. This gives publishers participating in ProRata a tangible visibility benefit alongside the per-citation revenue, because Gist.ai cites sources prominently and at high frequency.
When to Choose TollBit
Choose TollBit when your content is high-volume and broadly fetchable, when revenue predictability matters more than peak per-citation rates, when you want a broad AI-buyer mix that includes major labs, and when the operational simplicity of per-fetch pricing aligns with your team's capacity. Most general-news and B2B-media publishers fit this profile.
When to Choose ProRata
Choose ProRata when your content is differentiated and high-contribution, when peak per-citation rates matter more than predictability, when the attribution-aligned AI-buyer mix matches your target audience, and when you want demonstration through Gist.ai. Most premium news, primary research, and specialty content publishers fit this profile.
When to Run Both
For publishers with mixed inventory (some commoditised, some differentiated), running both is often the right answer. Use TollBit for the high-volume commoditised inventory and ProRata for the differentiated inventory. The marketplace dashboards are independent, so the operational overhead is moderate.
How Presenc AI Helps Decide
Presenc AI computes Citation Value Score across content inventories and predicts which marketplace will produce higher revenue for which content tiers. Pages with high content-quality and authority signals typically perform better on ProRata; pages with high crawl-volume but moderate content-quality signals typically perform better on TollBit. The CVS-driven recommendation gives publishers a defensible answer to the marketplace-mix question rather than guessing.
