GeraNexus vs Zapier
Zapier automates workflows between SaaS apps when events happen. GeraNexus is a commerce protocol that lets AI agents book real-world services, pay with escrow, and verify delivery — with dispute resolution built into the spec. Zapier automates human-initiated internal processes. GeraNexus enables AI agents to transact commercially. They operate at different layers and are not substitutes.

Frequently asked questions
What is the fundamental difference between GeraNexus and Zapier?
Zapier automates workflows between existing SaaS apps — when this happens in App A, do that in App B. GeraNexus is a protocol that lets AI agents conduct real-world commercial transactions: book a home service, pay for a consultation, hire a worker, and verify service completion — with escrow, dispute resolution, and audit trails. GeraNexus is transactional; Zapier is event-driven workflow automation.
Can Zapier be used by AI agents to make payments or bookings?
Zapier can trigger actions in connected apps (like creating a booking record), but it does not handle payment escrow, service-delivery verification, dispute resolution, or signed agent-action audit trails. GeraNexus treats these as first-class protocol concerns, not afterthoughts.
Does GeraNexus replace Zapier?
No. GeraNexus is not a general workflow automation tool. It is a commerce-layer protocol designed specifically for AI agents that need to interact with real-world services. Zapier remains useful for automating internal SaaS workflows. They complement each other at different layers of an AI-powered stack.
Is GeraNexus only for Gera products?
No. GeraNexus is an open protocol. Any service provider can publish a /.well-known/gera-nexus.json descriptor and become reachable by any AI agent that speaks the protocol. Gera provides the reference implementation across its own 35 products, but the spec is open for adoption.
How does escrow work in GeraNexus?
GeraNexus defines a pluggable settlement layer with escrow held until the verify-completion step. The reference implementation uses GeraCash and Stripe with authorise, capture, and refund semantics. The AI agent authorises payment, the provider completes the service, GeraWitness (optional) verifies, and the escrow captures. If disputed, a resolution process is defined in the protocol.
The commerce layer for AI agents
Open protocol — any service can implement. Any agent can transact.
