Pricing
How each of the two lines is priced, the figures, how you pay, and how Japanese consumption tax actually works on a service bought from abroad.
Two lines
| What you buy | Who it is for | |
|---|---|---|
| Monitoring | The answer — it runs every morning and the result arrives | Commerce, marketing and buying teams who do not write API calls |
| API | The connection — POST /v1/extract and the Browser API | Developers, data teams, agencies |
Both sit on one platform and share one key, one bill and one audit trail.
What the monitoring line is priced on
| Axis | Why this axis |
|---|---|
| Products monitored | It matches the unit the business thinks in. "500 products" survives an approval memo; "1,000 URLs" does not |
| Number of sources | Not charged. Charging for sources makes customers cut sources, which thins the comparison and bends the answer |
| Frequency | Daily, twice daily, four times daily — within what each source permits |
| History retained | The record of what disappeared. It is worth more the longer it runs |
Setting up a new source is a one-off charge, not a monthly one, because it is a one-off piece of work.
What the API line is priced on
Successful requests. That is all.
- Failures are not charged. 5xx, timeouts, and anything not fetched because
robots.txtdisallowed it cost nothing - There are no multipliers. JavaScript rendering and browser sessions are the same one request
- The LLM tier is charged only where it produced the value. Requests that never reached it carry no model cost
Why no multipliers
The larger vendors in this market bill in "credits", where one request can cost between 1 and 125 of them. The unit price is not settled until the invoice arrives.
This is not hypothetical. A customer of one such vendor wrote publicly: *"I woke up yesterday to a bill 40x times more than what was expected"*, and *"They advertise a feature to set a spending limit, but there is no option."*
A product that refuses to publish a figure it cannot defend cannot settle its own prices after the fact.
Why not per request
A listing page yields fifty items at once, and the cheap tiers involve no language model. Six times the data does not cost six times as much — it costs less than twice as much.
Charging per request prices the part that is nearly free, and gives you a reason to check less often. Checking less often is the opposite of what this is for.
Japanese consumption tax, accurately
Buying a service from abroad does not automatically cost a Japanese buyer an extra 10%. Which rule applies depends on the vendor.
| Mechanism | What it actually costs | |
|---|---|---|
| Business-facing services (terms make it clear it is sold to businesses) | Reverse charge — the buyer accounts for it | Where the buyer's taxable-sales ratio is 95% or above, reverse charge currently does not apply at all |
| Consumer-facing services (anyone can sign up) | The foreign vendor accounts for it | Deductible if the vendor is a registered qualified-invoice issuer. Not, if it is not |
So check the vendor's registration number rather than assuming. Japan's tax agency publishes a lookup.
Kansoku is operated by FID Ltd., a Japanese company, and issues qualified invoices. Our registration number is T4011101061208 — look it up at Japan's tax agency. There is no category to determine either.
How you pay
| Card | Processed by Stripe. Card details do not pass through our servers and we do not store them |
| Bank transfer against an invoice | Available on the higher plans. Over 60% of Japanese B2B payments are made by transfer or direct debit |
| Quotation | Issued on request, in a form that can be attached to an internal approval |
| Currency | Japanese customers are billed in yen, so no 3–4% foreign-transaction fee applies |
Annual totals are shown next to monthly ones. Japanese delegation-of-authority rules aggregate payments with the same purpose into a single item, so monthly pricing does not lower the approval threshold — there is nothing to gain by hiding it.
Prices
Beta pricing. It may change. All figures are exclusive of tax. Japanese customers are billed with 10% consumption tax added. Customers who join during the beta keep the price they joined on. Any increase is announced 30 days ahead.

Five products, free, no card. Sign up and start watching immediately; the first real morning message arrives the next day, and history is kept for 14 days. Nobody should have to file a purchase request for something they have not seen working.
Sources are not charged for. Watch a product on three sites or thirty for the same price — charging for sources makes customers cut them, which thins the population being compared and bends the answer.
The practical guide is around ten sources per product. Well beyond that, talk to us. We will not cut you off. We tell you first and decide together.
API
| Free | 1,000 requests a month, every month, no card. Two concurrent, ten a minute |
| Metered | ¥62 per 1,000 requests (ex tax), successful ones only |
| Spend cap | Set in currency, and it stops when reached |
No multipliers. JavaScript rendering and browser sessions are the same one request. The LLM tier adds only for the extractions that tier actually completed.
Which one
You want to know who is selling it and for how much → monitoring. No code.
You want it inside your own system → the API.
Approaching the monitoring ceiling → the API is cheaper for you, and we will say so. There is no reason to keep selling a monitoring plan to somebody who only needs volume.
Why these figures
The monitoring line is not selling fetches. It is selling matching, normalisation to a tax-exclusive figure, the record of where each number came from, the difference between a failure and an empty market, and the fact that it arrives every morning.
We do not publish comparisons on this page. Comparing honestly means lining up the tax treatment, the exchange-rate date, the billing period and what is actually included — products, sources, frequency, history. Numbers lined up carelessly come out in our favour, and a product that does not retract figures cannot retract a comparison either.
If you are evaluating someone else, we will build that comparison with the conditions matched. It will be faster than doing it twice.
