Baron Munchausen 0.5.0

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 There used to be six — Free, Solo $19, Pro $49, Team $149, Scale $499, Enterprise — and they were withdrawn on 7 September 2026 when reads and writes became free.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.

Free

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.

ProductPriceState
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.
