Signed governance receipts
Hosted allow decisions include signed governance receipts that downstream services can verify, and the SDK includes an optional enforcement wrapper for protected handlers.
AI Decision Governance API
Govern AI Decisions Before They Execute
Prime Form Calculus is a governance API that evaluates AI actions against policy rules before execution, verifies authorization, and turns each governed decision into a signed, tamper-evident, and verifiable record.

Verifiable Audit Record
Prime Form Calculus turns AI decisions into signed, tamper-evident, and verifiable governance records.
Tamper-evident decision chains
Receipts link together in append-only order so teams can detect broken continuity instead of trusting ad hoc logs.
Version-locked decision replay
Stored runtime provenance makes historical decisions replayable against the evaluator version that originally produced them.
Signed and verifiable evidence
Teams can retrieve, verify, and review governed decisions as durable audit records rather than transient application output.
Built for secure AI governance
- Signed governance receipts
- Version-locked decision replay
- Multi-tenant isolation
- API-first architecture
PFC Integrations
Installable Python packages for execution-boundary integrations
PFC is the execution-boundary control plane. The ecosystem access layer now includes installable Python packages for teams looking for a PFC Python package, an execution-boundary Python package, or a practical LangChain governance adapter without replacing the hosted runtime.
Explore PFC integrations for developers to choose the official pfc-client SDK, install pfc-core, or use the live pfc-langchain adapter with clear package links and working snippets.
Enterprise-Grade Governance
Prime Form Calculus is designed to help organizations govern automated decisions in environments where policy enforcement, auditability, and operational control matter. Teams mapping the problem space can move from AI execution risk into execution control at the execution boundary.
The first step is recognizing that AI execution risk appears when outputs become actions in production.
Policy Enforcement
Every AI decision request is evaluated against defined governance policies before execution.
Signed and Verifiable Evidence
Each decision remains available as signed evidence in a tamper-evident decision chain, and allow decisions include a verification-ready governance receipt.
Fail-Closed Safety
If a request violates policy or authorization rules, the action is blocked before it can execute.
Tenant-Isolated Infrastructure
Each organization's policies, API keys, and governance records are securely isolated.
