A pricing page is not one number. It is a set of small decisions about what to show, in what order, on which surface, and each of those decisions changes what a given figure actually promises you. The three examples below are already in our tool profiles, each with the document it came from and the day we opened it, so this post is a demonstration of the method rather than a new claim about any of the three vendors.
Does the price change when you flip a toggle?
Yes, on plenty of subscription pages, and the two figures often sit on the same card with no visible label saying which billing period produced which one. A screenshot taken with the wrong toggle selected reads as a fact, and it is one, just not the one you meant to capture.
Synthesia's Starter card displays a lower figure when the annual toggle is selected. The number on our profile, $29/mo, is the monthly one, and the profile says so in its body text rather than in a note beside the ledger row. If you find a different figure for the same plan somewhere else, on a slide deck or in a chat thread, the two are not necessarily in conflict. They may simply be two states of the same toggle.
Try this on a page we have not written about. Open the pricing card for a tool you have not looked at before. If it carries an annual or monthly toggle, read the price in both positions before you write either one down, and note which position you are quoting.
Is the number you found for the product you're about to open?
Not always. A company can publish a precise, dated rate on one surface of its product while the surface a new customer would open prices something else, or has stopped existing altogether. Matching a figure to the right document does not mean matching it to the right product.
OpenAI publishes a per-second API rate for Sora, $0.10 per second (720p, sora-2), on its developer pricing page. There is no consumer price to set beside it: OpenAI discontinued the Sora apps on April 26, 2026, and has published that the API follows on September 24, 2026. An API rate was never what trying the consumer product cost, and treating the two as one number would put a developer's price in front of a reader who is not writing code.
Before you carry a number away from a tab, check what that tab is actually for: an API reference, a partner sheet, an enterprise deck, or the signup flow you would use yourself. Two pages on one domain can price two different products, and only one of them is the one you are about to open.
What happens to the row when there is nothing to publish?
Two different things, and they are not the same finding. A vendor can leave a field off the page entirely, which tells you only that we could not find it there. Or a vendor can print a specific word in that field, stating there is nothing to offer, which is the vendor answering the question rather than skipping it.
Google's Gemini API pricing page prints Not available in the Veo free tier row. That is not a gap in what we could find. It is Google stating the answer. A printed absence is more useful to plan around than a row that is simply not there, because it removes the guessing: on that surface there is no unpaid evaluation to look for, so the first dollar you spend is the cost of finding out whether the tool suits you. We did not check Google's consumer products for a separate way in.
Look for a field on a pricing page that could plausibly sit empty: a free tier, a trial length, a rate limit. Check whether the row states an absence in words, or whether it is simply missing from the page. Only the first of those is the vendor telling you something. The second just means keep looking.
None of the three checks above requires reading between the lines. Each is a sentence the vendor already wrote, sitting on a page anyone can open. That is why every figure on this site carries the document it came from and the day a human opened it: not because we distrust a number, but because a number without its source is a claim you cannot go check yourself. Our methodology sets out how that record is kept.
