Open-Source Protocol

Authorization Protocol
for AI Agents.

Irreversible real-world actions execute only within human-defined bounds — enforced through cryptographic attestations and runtime verification.

How HAP Works

HAP separates authorization from execution. Humans authorize actions through cryptographic attestations. Gatekeepers verify those attestations before any system is allowed to execute.

Executor

Service Provider

Issues cryptographic attestations proving a human authorized an action within defined bounds.

Gatekeeper

Verifies attestations before execution and blocks any action that exceeds authorized limits.

Executor

Performs the action — but only after authorization has been validated.

HAP enforces authorization through two infrastructure components: Service Providers issue attestations. Gatekeepers verify them before execution.

AI Executes. Humans Own It.

AI Agents can deploy code, move money, grant access, and operate infrastructure. But they cannot own it — because ownership requires bearing consequences, and AI cannot bear them.

HAP ensures that irreversible actions only execute within bounds set by a human who owns the outcome.

Direction is human. Execution is machine.

AI can:

optimize, coordinate and execute.

Humans must:

define what to optimize, set objectives, accept tradeoffs and bear consequences.

HAP enforces that boundary.

Compliance Alignment

HAP turns policy requirements into enforceable infrastructure.

EU AI Act

Article 14 mandates effective human oversight for high-risk AI. HAP satisfies this structurally — oversight is not a checkbox, it's the architecture.

ISO 42001

Every AI action requires a human Decision Owner who has articulated the problem, objective, and tradeoffs. No attestation, no execution.

NIST AI RMF

Every decision produces a cryptographic trail of authorship, tradeoffs, and commitments — tamper-proof and verifiable.

Build With HAP

HAP turns human direction into the governing layer of intelligent systems.
