Three enterprise plans, the Lemma API for developers (auth included), and Trust402 for agents (Pay / Sell).
Civic / Critical / Compliance — public, critical, and financial systems. Monthly + setup.
See the 3 plans →The ZK proof issuance API — per-class, usage-based (auth suite included).
See the rates →Pay / Sell + Institutional ID. Four self-serve plans.
See the 4 plans →Pricing is set by scale (sites, facilities, organization size) and what you want to do (your use cases).
Configured for custom development, on-premises, and business continuity.
Talk to us →Configured for custom development, regulatory compliance, and audit trails.
Talk to us →A monthly platform fee (tiered by scale, annual contract) plus an initial setup fee that builds the proofs for what you want to do. Civic uses standard templates; Critical / Compliance are custom-quoted for bespoke development and regulatory work.
The setup breakdown (proof-template design, API integration, front-line screens, integrated development) is walked through at Discovery / quote time.

Scope: Option Packs add on from Tier 2 on Critical or Compliance. Civic is out of scope (public-utility pricing preserved); Tier 1 is out of scope on every plan (lightweight tier). Pack combinations get designed against business requirements in the Discovery session.
Enterprise (Civic / Critical / Compliance): configuration designed against business requirements, a PoC, then production. The Lemma API and Trust402 are self-serve from the Sandbox — a separate path.
Issue proofs of provenance, authentication, authority, inference, and attributes from the raw API. Verification is always free — you pay only to issue.
No monthly fee. Each proof settles per issuance via x402. Verification is always free.
Reference pricing — final rates are set at the API's public launch.
| Proof class | Rate (USD) | Detail (proof) |
|---|---|---|
| Provenance Prove origin without handing over the original. | 0.005 | → |
| Authentication Prove identity without sending a key. | 0.01–0.05 | → |
| Authority Delegate authority without handing over a key. | 0.05 | → |
| Inference Prove inference without disclosing the model. | 0.07 | → |
| Attribute Prove you meet a requirement without revealing the attribute. | 0.20 | → |
Production billing is coming soon — start free on the testnet Sandbox. Rates, concepts, and issuance steps are consolidated on each proof page.
Pay (agent payments) and Sell (list your work). One issuance allowance covers both.
Pay and Sell share one issuance allowance — every plan covers both. Verification is always free; 0% commission on sales.
Enterprise pricing varies with tier, site count, SLA, and the complexity of the proof logic. Numbers without context mislead, so we design against your actual use case. (The Lemma API and Trust402 rates are published on this page.)
Citizen-facing services and utilities → Civic. AI embedded in operational systems with business-continuity demands → Critical. Attribute verification, audit trails, regulated workflows → Compliance. Issuing proofs from the raw API → Lemma API. Agent payments and listings over x402 → Trust402. We sort it out together in a Discovery session.
Trust402 and the Lemma API both have a testnet Sandbox (Explorer). Enterprise evaluation runs via a scoped PoC.
Enterprise plans are annual contracts: monthly base + verification volume + optional custom-schema registration, plus Option Packs when relevant. Discovery returns a Tier + Pack proposal from Lemma.
Option Packs aren't sold standalone — they can be added on Critical / Compliance Tier 2 and above. We intake your business requirements in Discovery and propose a Tier + Pack configuration. Civic and Tier 1 on every plan are out of scope.
Yes. Lemma integrates via API and doesn't replace the systems you use. When you need front-line screens, we quote them individually as integrated development.
Yes. Every enterprise tier is designed to move up as the deployment grows.
Issuance rates are fixed per proof class (provenance 0.005 / authentication 0.01–0.05 / authority 0.05 / inference 0.07 / attribute 0.20 USD). Verification is always free. Production billing is coming soon; until then you can try it free on the testnet Sandbox. Flat-rate quota / grade plans are coming soon too.
The four Trust402 plans (Explorer / Builder / Pro / Institutional ID) are listed on this page. Production billing is coming soon; you can try it free on the Explorer Sandbox.
Pay is the AI agent's payment; Sell is listing what it produces. Both draw on a single issuance allowance — no need to split plans. Verification is always free and the sales commission is 0% (you keep 100%).
Each proof issuance settles per-use in USDC over x402 (metered, no minimum). Verification is free and Lemma never touches your revenue (0% commission). To try it first, the Explorer tier is unlimited and free on testnet.
We return a configuration matched to your industry and scale within one business day of the Discovery Call.
