Mnemom has no plan tiers. Every feature (the gateway, integrity checks, alignment cards, reputation, the dashboard) is available to every account from the start. You pay for work as it happens, in μ.
For estimates at your own volume, use the pricing calculator.

​
The unit

1 μ = $0.01 USD. The peg is fixed and will not be re-denominated, so a μ balance reads directly as a dollar amount. Charges are recorded in thousandths of a μ and rounded up, so a small model call can cost a fraction of a μ.

​
Getting μ

1

Sign up free

No credit card required to create an account and explore the product.
2

Add a card, get 10,000 μ

Adding a payment method triggers a one-time introductory grant of 10,000 μ (worth $100 at the peg). It’s a grant, not a charge. Nothing is billed until you spend past it.
3

Buy more, or turn on auto top-up

Purchase any amount of μ in one click, or set a threshold and target so your balance tops itself up automatically when it runs low. There’s no minimum purchase.

​
What you pay for

The rule is simple: when the gateway calls a model to do work for you, that call is charged at 5× its measured model cost, which is an 80% margin. The cost is measured per call from the tokens it used, at the model provider’s list prices. A step that makes no model call costs nothing. Prices on this page match Mnemom rate card v2026-09-gateway.

Work that needs no model call

​
What is not charged

  • Your own model inference. When you send requests through the gateway with your own provider key (BYOK), the model call you asked for is passed through. Your provider bills you for it; Mnemom does not. You pay Mnemom only for the gateway’s own model calls in the first table above.
  • Work that needs no model call, as listed in the last table.
  • Everything else on this site (agent registration, alignment and protection cards, the dashboard, reputation lookups) has no per-call charge today.

​
A worked example

A governed turn’s integrity analysis uses 0.002(0.2μ)ofmodeltokens.At5×thatis1μ.Oneoftheturn′ssurfacesalsoescalatestotheSafeHouselevel2model,andthatcalluses0.002 (0.2 μ) of model tokens. At 5× that is 1 μ. One of the turn's surfaces also escalates to the Safe House level 2 model, and that call uses 0.0004 (0.04 μ) of model tokens. At 5× that is 0.2 μ. The turn costs 1.2 μ in total. If Safe House had cleared every surface at level 1, the screen would have cost nothing.

​
When your balance runs out

There is no overdraft and no credit line: your balance never goes below 0 μ. A charge your balance cannot cover is refused, and the gateway rejects requests with 402 Payment Required (see Errors) until you add μ. To avoid a gap, turn on auto top-up before you need it.

​
When μ expires

Each purchase or grant of μ is kept as a separate lot, and each lot has a 12-month expiry clock. The clock starts when you buy or receive the lot. Every charge except a settled reservation (below) restarts the clock on each lot it draws from. A lot that goes 12 months without such a charge expires, and its unspent μ is removed. The exception: a ResearchGrade run reserves μ when it starts and settles the reservation when it completes. Settling draws from your lots but does not restart their clocks. If ResearchGrade runs are all you spend μ on, a lot still expires 12 months after you bought it, or 12 months after the last other charge drawn from it. Grants (such as the introductory 10,000 μ) are spent before purchased μ, and purchased μ is spent oldest first, so in normal use your oldest lots are the ones being drawn down.

​
Checking your balance and usage

  • Dashboard: www.mnemom.ai/settings/billing shows your current μ balance, and /settings/billing/usage breaks down consumption over time.
  • API: GET /billing/mu returns your org’s current μ balance, GET /billing/mu/ledger returns every ledger entry (grants, holds, settlements, refunds, expirations) behind that balance, and GET /billing/mu/statement returns an itemized monthly statement for a given YYYY-MM period. See the Mu balance, Mu ledger, and Mu statement endpoint references.
  • Payment methods and receipts: GET /billing/payment-methods lists your saved payment instruments (tokenized, so full card numbers are never returned) and GET /billing/receipts lists your completed μ purchases. See the Payment methods and Receipts references.
  • CLI: mnemom usage --org <org_id> shows per-person token and request consumption for an org, filterable by --days, --person, --provider, and --model. See the CLI reference.

​
Enterprise

An annual μ commitment unlocks a volume discount off the list peg. Retail purchases always stay at list price, with no discount tiers: Enterprise also adds self-hosting (run the trust plane in your own infrastructure, same μ accounting and peg) and dedicated cells (an isolated deployment in the region you choose). Contact sales for a quote.

FAQ

μ is the unit you pay in. One μ is one US cent, and the peg is fixed.
The model calls the gateway makes for you (governed turns, Safe House level 2 escalations, context folds, and observer trace analysis), each at 5× its measured model cost, plus the fixed-price API products listed above. Work that needs no model call is free, and your own model inference sent with your own provider key is not charged.
Level 1 screening, which runs rules and makes no model call, is free. When a surface escalates to level 2, that model call is charged at 5× its measured cost.
Sign up for free with no card required. Add a payment method and you receive a one-time grant of 10,000 μ ($100 at the peg). Nothing is charged until you spend past it.
Your balance never goes below 0 μ. A charge it cannot cover is refused, and the gateway rejects requests with 402 Payment Required until you add μ. There is no overdraft. Buy more μ in one click at any time, or turn on auto top-up so your balance refills once it drops below a threshold you set.
Yes. Each lot of μ expires after 12 months without a charge drawn from it. The clock starts at purchase, and every charge except a settled ResearchGrade reservation restarts it. See “When μ expires” above.
No. Every feature is available to every account regardless of spend. Buying more μ buys more work done, not more product.
Your dashboard’s billing pages show your balance and usage; GET /billing/mu, GET /billing/mu/ledger, and GET /billing/mu/statement expose the same data by API, and mnemom usage shows per-person consumption from the CLI.
