Keep a tamper-evident record of every decision — allow or deny — so you can prove after the fact exactly what each agent did and under whose authority.
An ordinary log can be edited. Liceat records every authorization decision as a leaf in an append-only Merkle transparency log, signed by the issuer key. Anyone can verify that a record is present and that the log has only ever grown — the same guarantee that secures the web's certificates, computed instantly and without a blockchain.
Export a self-verifying compliance bundle for an auditor: they recompute the Merkle root and re-run the hash chain to confirm the record is complete and unaltered — with zero trust in you.
Liceat is permission infrastructure for AI agents. You issue a warrant — a scoped, spend-capped, revocable token — that grants an agent narrow authority; the agent presents it at the point of action; Liceat enforces it (scope, spend, rate, holder-binding, revocation) and records every decision in a tamper-evident log. It is open source with a zero-dependency SDK for TypeScript and Python.
The SDK and self-hosted gateway are free and open source. The hosted gateway at liceat.com gives 10,000 free decisions with no card, then meters at fractions of a cent per decision — payable by card or USDC.
Free to self-host. 10,000 free decisions on the hosted gateway — no card.
