Subscription figures are provider list prices recorded in treg.to’s own catalog grid; per-call prices are what treg.to charges today, with $0.000 added.
set up treg — https://treg.to/llms.txt
Using treg, get the top 200 keywords stripe.com ranks for in Google in the United States, with position and monthly volume. Show me the price first, then group them by position band.
A domain ranks differently in each country's index. Say which one, or you get the provider's default.
Row count is the cost dial on most of these rows. A limit you chose beats a default you did not.
Both arrive in the same row. Asking for them separately is two calls for one answer.
treg.to returns the cost before the call, so the agent can say what it will spend.
treg.to holds the provider keys. Neither you nor the agent sees them.
The provider's own rate, $0.000 markup, from a prepaid balance.
Charged per call. $1.00 free per new team, no card to start.
Already pay Hunter? Register it and those calls are never metered.
Another provider is a different word in the prompt, not a new integration.
No SDK, no OAuth dance per vendor, no seats.
treg.to does not choose for you. It hands ChatGPT this comparison, with the price shown before any call, and ChatGPT picks. Or you tell it how: "cheapest", "most reliable", "the one that takes what I have", or a provider by name.
DataForSEO at $0.012
Serpstat at $0.0005
Those units are not interchangeable: one call can return many results, so compare on the unit you will actually be billed in.

From eight searches across Reddit and X in August 2026, of which only about 13 posts were both on topic and organic. Thirteen more were a single coordinated cluster promoting one vendor across three small subreddits, seeding the question in one and answering it in another, with non-breaking spaces left mid-sentence in the bodies. SEO is the most astroturfed category this loop has researched, so the surviving posts are quoted and the rest are only counted.
“Don't really want to drop $14K to have access to the ahrefs API, so I'm hoping there are other, high-quality options” r/bigseo, 1 point
What this page can do about it: Worth quoting and then correcting, because the correction is the useful part. That figure is an old enterprise tier and the research found it has since moved, so check the vendor's current page rather than a thread. Then apply the same suspicion here: every price in the comparison above carries the date it was read off the provider's own rate card or documentation, because a price without a date is the thing that misled this reader.
“Semrush starts at $120/month. Ahrefs is up there too. For a bootstrapped operation that's a real cost” r/DigitalMarketing, 82 points
What this page can do about it: The objection in the research was almost never the total, it was the variance: a flat monthly fee prices the quiet months wrong, and this work arrives in bursts. Every row here is per call from a prepaid balance with no minimum and no commitment. The honest trade is that you get an index and a raw response rather than a curated keyword universe with a difficulty score on top, and the difference is your own development time.
“Sometimes it works perfectly, other times it gives a completely different result to what we see if we visit Google in the browser” r/SEO, 7 points
What this page can do about it: No comparison table can tell you whose index is right, and this one will not pretend to. Nobody publishes a methodology, every accuracy claim is made by the vendor selling it, and the phrase keywords a domain ranks for means a different keyword universe at each provider before you compare a single position. The only honest offer is a procedure: run the same fifty keywords through two of these for a week, diff both against your own Search Console, and keep the one whose error is stable rather than the one whose number is highest. At these prices that experiment costs less than a coffee.
“I wanted to do some keyword research yesterday and was surprised by how expensive Ahrefs / Semrush were.” r/TechSEO, 36 points
What this page can do about it: This post ends in an open source interface over a raw data API, and it was the most common constructive answer in the research by some distance. That audience does not need a feature grid, it needs the call, the response shape and the real per call price, which is what the comparison above and the runnable call under it are for. The part nobody warns them about is the unit: two of these rows bill the request and two bill the row.
“Tried DataForSEO but couldn't get the traffic endpoint working properly - they provide estimated traffic value instead of traffic.” r/Agentic_SEO, 12 points
What this page can do about it: Fair criticism of a provider on this very page, and it generalises past that provider. Position is close to observable, since somebody looked at a result page. Volume and traffic are not: every vendor here derives them, none of them measures them, and the numbers differ because the models differ. Treat position as data and traffic as an opinion with a price on it, and the disagreements stop being surprising.
DataForSEO charges per request plus a fraction of a cent for each keyword returned. SE Ranking charges a flat hundred credits per request and nothing per record, so one page of a thousand rows costs a fraction of ten pages of a hundred. Serpstat charges a credit per keyword and bills its one credit minimum even when nothing comes back. Read the unit column before the price column.
Its pricing table gives a range per thousand rows across the research endpoints and does not say which tier this one sits in, so the catalog carries the upper bound instead of guessing low. Read that row as a ceiling and the others as rates. Its page size also defaults to five, so set it explicitly or the call returns almost nothing.
It bills in API units bought in packages up front, ten per line returned, so what a pull costs depends on the package you hold rather than on any public per call rate. A default request there returns ten thousand lines, which is a hundred thousand units, so send a display limit before you send anything else.
One row per keyword the domain appears for in the provider's index of Google: the keyword, the position it holds, the search volume behind it and usually a cost per click and a landing URL. It is a snapshot taken from an index that vendor already maintains, not a live search run for you, which is why it can return thousands of rows for the price of one request and why two vendors will hand you different lists for the same domain.
Not in the sense of a tracker you configure and leave running. These return the keywords a domain ranks for right now, from each vendor's index, in one call. Nothing here schedules itself, keeps a history for you or alerts you to a drop; if you want positions over time you run the call on your own schedule and store the results. treg.to has no scheduled rank tracker on the menu, and saying so is more useful than a near miss.
A cent or two per request on the rows that bill the request, and a fraction of a cent per keyword on the rows that bill the row, at the provider's own rate with $0.000 added by treg.to. The comparison above prints both, and which is cheaper depends entirely on how many keywords you ask for.
Because each one is answering from its own index, built by its own crawl on its own schedule, and the phrase keywords a domain ranks for is a keyword universe that differs before a single position is compared. No table settles this. Running two of them against your own Search Console for a week does.
Yes, and that is the point. Search Console is ground truth for sites you own and silent about everybody else, so a competitor's ranked keywords have no first party source at all. The target is just a domain on every row here, which is why this job exists as something you pay for.
