APICostCalc is read by people at the moment they are choosing an API and budgeting for it — engineers costing an AI feature, founders sizing a stack, engineering leads justifying spend. That is a narrow, expensive-to-reach audience arriving with commercial intent, which is why we sell placement rather than run a display network.
| Metric | Detail |
|---|---|
| Primary audience | Backend and AI engineers, technical founders, engineering managers costing infrastructure |
| Most-read pages | LLM price comparison, per-provider pricing guides, AI app and RAG cost estimators |
| Traffic source | Organic search on high-intent queries — "claude api pricing", "rag cost calculator", "how to get an X api key" |
| Intent stage | Evaluation and budgeting, i.e. immediately before a build-or-buy decision |
| Coverage | 300+ calculators and provider guides; 380+ AI models tracked with price-change alerts |
A native "Sponsored by" card directly under the result on one calculator page: your logo, one sentence, one link. Clearly labelled. Best for a product that is genuinely the answer to the question that page asks — an observability tool under the observability cost calculator, a gateway under the gateway markup calculator.
Your brand in the tools strip that appears on every page, alongside the hosting and developer tools we already recommend. Best for products with broad relevance across the whole catalogue rather than one workload.
We write it, with real numbers, the same way we write everything else on the blog — no press-release copy, and we will publish a figure that is unflattering to the sponsor if that is what the arithmetic says. Labelled as sponsored, and the link stays up permanently rather than being pulled at the end of the month.
A co-branded calculator built around your pricing model, newsletter placement, data licensing from our price-change tracker, or a revenue-share arrangement. These are scoped individually.
That last one is the constraint that matters. This site's only asset is that the numbers are not for sale. A sponsorship buys placement and attention; it does not buy a better position in a comparison table, and we will say so publicly if asked.
