Grantex – OAuth 2.0 protocol tailored for AI agents with scoped, revocable access

Summary: Grantex provides a secure authorization protocol for AI agents, enabling scoped, time-limited grants instead of all-or-nothing API keys. It issues signed JWTs verifiable offline and logs all actions in an append-only audit trail, allowing fast revocation and detailed tracking.

What it does

Grantex assigns cryptographic identities to agents and lets users approve scoped grants via a consent UI. Agents receive signed JWTs that services verify offline using JWKS, supporting delegation to sub-agents and logging all actions in a hash-chained audit trail.

Who it's for

It is designed for developers and organizations managing AI agents that require fine-grained, auditable, and revocable access to APIs and services.

Why it matters

Grantex addresses the lack of tailored authorization for autonomous AI agents, reducing over-permission risks and enabling transparent, fast revocation and auditability.
