One operation costs money
Storing, searching, reading, writing, exporting — free,
for ever, on your own machine and on ours. The verdict is the only thing
we charge for, because the verdict is the only thing here that nobody
else sells.
There are no tiers on this page. There used to be six —
Free, Solo $19, Pro $49, Team $149, Scale $499, Enterprise — and they
were withdrawn on 7 September 2026 when reads and writes became free.
A page that still sold them would be selling something we decided not
to sell.

The engine, self-hosted
- All 27 tools, Apache-2.0
- Reads and writes: checkpoint, search, recent, add, update, rewrite
- The P1–P6 gate, the duplicate gate, the audit journal
- Obsidian export and ingest, the project thread, the limits tracker
- The catalogue of 1507 public APIs, re-probed on a schedule
- Local grounding, with no call leaving the machine
0.0035 USDC per verdict
Hosted memory_ground
- The only paid operation, on the calibrated corpus and thresholds
- Charged per call, in USDC on Base through x402
- No subscription, no account minimum, no key needed to be quoted a price
- Reads and writes stay free — there is no per-operation charge
- The price is temporary and holds until we have measured what a
verdict actually costs to produce
A session under the full contract is three calls —
prepare, ground, add — of which one is billed. Everything on this page is
payable in USDC on Base; there is no card yet, and that is a gap we name
below rather than hide.
Why the verdict and nothing else
- Storage is not scarce
- The market settled this: keeping and retrieving memory is free
almost everywhere, and processing is what gets billed. Charging per
operation would have made a session eight to ten times the cost of the
nearest comparable service for something nobody considers a product.
- The verdict has no competitor
- Fifteen memory layers were surveyed. Not one returns a number that
says how much of an answer its own memory backs. That is the one thing
here worth a price.
- The price is provisional and labelled as such
- 0.0035 USDC was chosen before the cost of producing a verdict was
measured, because changing a price twice is worse than setting it once
from data. The measurement is blocked on a token budget, and when it
lands the price moves in public.
- Self-hosting is not a downgrade
- The local verdict uses the same code. What the hosted one adds is a
corpus and thresholds we keep calibrated — and a round trip, which is
the honest trade.
Priced, decided, not built yet
Two products have a price and an owner’s decision behind
them, and no code. They are listed because the price is real and the
absence is real; nothing on this page can be bought today except the
verdict.
| Product | Price | State |
| Delta analyser
Reads what changed in a repository since the last
run and reports it on a schedule. Daily by default; weekly costs the
same. |
$12 / monthor $0.50 a day |
not built |
| Product map
A one-off pass over a repository that returns what
it contains and how the parts stand to each other. |
$1 up to 200 files$3 up to 1000 |
not built |
Above 1000 files there is no tier: that case is quoted, not
priced. The daily option exists so the analyser can be tried without a
subscription, and it is aimed at agents paying per run — a card would lose
most of $0.50 to its own fee.
Three things we are considering, and have not done
Every one of these is a proposal with a reason and a risk,
waiting on a number the owner has not set. They are printed here in the
state they are actually in, because a promise with a broken counter behind
it reads as a lie — and that is exactly what the old page did with
“first 1,000 claimed / 1,000” pointing at a route that answered 404.
A free allowance on verdicts
not live
N verdicts a month at no charge, then the per-call
price. It puts the boundary exactly where the value has been felt and no
money has been taken yet.
Blocked on: N without a cost measurement is a guess, and
the measurement is the same one holding up the price itself.
A fixed price for early subscribers
not live
The first N paying users keep their price for as long
as they keep paying. It sells urgency honestly: nothing is taken away
from anyone who arrives later.
Blocked on: it is a commitment to hold a price, and the
price it would hold is not measured yet.
Referral
not live
A month of the analyser to both sides. The old footer
said “in preparation” for months with nothing behind it.
Blocked on: a counter and protection against a person
inviting themselves. Neither exists, so neither is claimed.
Paying by card
not live
Two payment paths — x402 for agents, a card for people
— was decided long ago and has not been built. Today a wallet on Base is
a hard requirement, which excludes everyone who simply wants memory.
Trade-off named: roughly $0.33 of fees on a $1
transaction eats the product map, so the card cannot simply be bolted
onto every price.
The numbers behind the pricing, including the bad ones
Measured 8 September 2026. Our own
test payments are counted separately rather than quietly subtracted.
| Revenue, lifetime |
$0.031 across both services, from
16 settled payments and
2 external buyers. That is the honest scale:
three cents. |
| Payers today |
0. The counter is published whatever it
says, and it says zero. |
| Paid routes already running |
18 on a sibling service, each with a free
preview. See the catalogue. |
| Cost of a verdict |
Not measured. The measurement needs cached-token
accounting from the model router, and the budget that would produce it
is spent. Until then, 0.0035 USDC is a placeholder that says so. |
| Withdrawn prices |
0.0035 USDC per memory operation and 0.005 USDC per query are both
cancelled, along with the six subscription tiers. If you find them
quoted anywhere, that page is out of date. |
Paid in USDC on the Base network through an x402 challenge:
the server quotes the exact amount, you pay from your wallet, and the
transfer is verified on chain before any service is rendered. No credits, no
token, no internal currency — an earlier version of this site advertised
one, and it is gone.
