How GeraNexus works
The protocol that lets agents act for you, safely and verifiably.
Quick answers
- What is GeraNexus?
- An open protocol that defines how AI agents discover services, request user consent, and execute typed actions on the user's behalf with full auditability.
- How is Nexus different from a normal API?
- APIs are call-and-respond. Nexus adds discovery, scoped consent, signed manifests, and standardised auditability so agents can act safely on a user's behalf — not just fetch data.
- Is the protocol open?
- Yes. Spec, schemas, and reference implementations are public. Anyone can publish a service or build an agent that speaks Nexus.
- Which agents support Nexus?
- Gera-built agents (GeraOS, Clone, Persona) plus a growing list of third-party runtimes. Adapters exist for ChatGPT custom GPTs and Claude tool use.
The journey, step by step
- 1
Discover
Agents discover services via the Nexus directory — typed actions, prices, rate limits, and provenance, all machine-readable.
- 2
Request consent
Before acting, the agent presents the user with a scoped consent screen — what, where, how much, for how long. Consent is granular and revocable.
- 3
Act and audit
Once consented, the agent calls the typed action. Every step is signed, logged, and verifiable. Witness flags anomalies in real time.
