Be in the answer, measured.
Between 9 May and 7 August 2026, VerticalAPI's comparison pages were cited 8,758 times in AI answers — 5,526 of them in the last four weeks alone. The questions behind those citations are buying questions: best inference provider for reliable function calling, Anthropic vs Cohere comparison, best LLM serving providers for coding assistant throughput.
The people asking never see a list of search results. They see one answer, and a handful of sources under it. Being one of those sources is the whole game — and it is measurable per page, which is why this offer can be priced honestly instead of sold on adjectives.

Every public provider we can reach
- Measured on the same harness as everyone else
- Price, context window and capabilities from your own docs
- Present in the comparison pages and the benchmark
- No payment, no account, no request needed
This is not a teaser for the paid tier. The corpus is only cited because it is complete and neutral; a directory that measured only its customers would stop being worth quoting, and then there would be nothing left to sell.
We run your endpoint, and publish what comes out
- Time to first token, measured — not quoted from your page
- Throughput under concurrency
- Cost per million tokens, input and output
- Function-calling reliability across a fixed prompt set
- A permanent page inside the corpus, re-run every quarter
- A quarterly report of how often that page was cited
Nothing is charged until we have reached your endpoint and agreed what gets measured.
The line we do not cross
€249 buys the run and the page. It does not buy the number, the ranking, or a kind word. If your endpoint is slower than a competitor's, the page will say so, and it will stay up saying so. If that is a problem, the honest answer is not to buy this.
The reason is not principle for its own sake. The corpus earns citations because it reads like a measurement, not a brochure. The day it reads like a brochure the citations stop, and the thing you paid for stops existing.
What this is not
It is not traffic. Over the same period these pages sent almost no human visitors — an AI answers the question and the reader rarely clicks through. If you are buying clicks, buy ads; they are better at it and they are honest about the unit.
What you are buying is presence in the answer itself, at the moment a developer or a CTO asks which provider to use. That is a different unit, it is newer, and this page reports it with its real name and its real source rather than dressing it up as visits.
How a run works
- You send an OpenAI-compatible base URL, the model ids, and a way to get a test key.
- We agree the scope in writing before anything is charged.
- The run goes through the same harness as every other provider in the corpus.
- You see the numbers before publication — to correct a factual error, not to change a result.
- The page goes live, and is re-run each quarter for as long as the endpoint exists.
