Verify LLM API
Check which model your AI agent is really using
What this is
Checks whether the AI model actually answering your API calls matches what the provider claims it is.
Our one-line summary — not the founder’s tagline.
- How it works
- samples one-token outputs and matches the distribution against known model fingerprints
- What's different
- covers 161 exact model IDs; unmatched cases return INCONCLUSIVE rather than a false positive
- Best for
- developers who need to verify which LLM is really running behind an endpoint

Dev. Launched 5d ago on Product Hunt, picking up 10 votes. Today, it's live, but nothing on the site has changed since we started watching.
Quiet for 5 days — no penalty yet, but quiet doesn't stay free.
We check this site every day, ourselves. A founder can post “still working on it” — a claim like that doesn't price. What we price is what we can verify from the outside: evidence, not announcements. The real question isn't “will this be huge?” — it's “will they still be moving in four weeks?”
The market viewHow this launch is priced and ranked in our league — the investor side of the page.
ranked by the reality anchor, not the market price
It launched on Product Hunt with 10 votes.
No matter how much money goes in. There is no pump here — you can't make yourself right by buying more. The line only moves on things that actually happened: an award, revenue that grew, a new platform, code that shipped — or silence.
A launch that goes quiet eases down a little at a time — never a cliff you could have run from the night before.
Daily tracking just started for this launch — the first point is on the board. A second reading lands with tomorrow's run, and the curve builds from there.
How the launch is moving on its own board, day by day — the crowd's attention.
A flat line is normal: votes stop within a day or two of launch, on every board. What's unusual — and what actually counts — is a launch that keeps pulling votes long after its day is over.
About
Verify LLM API checks whether the model behind your AI agent or API matches its claim. Tell a Codex agent to run verifyllmapi.com/run, or test an OpenAI- or Anthropic-compatible endpoint. It reuses the Agent’s login in fresh sessions, samples one-token outputs, and matches their distribution with public fingerprints using Jensen–Shannon distance. Credentials and raw samples stay local. The library covers 161 exact model IDs; unknown or weak matches return INCONCLUSIVE.

The board it did best on sets the price. Every other board only adds to it if the launch also placed high on that board too — because just showing up somewhere isn't an achievement. Listing on twelve directories is free; placing well on them isn't.
