Agent JSON

Protocol substrate for machine-to-machine trust. Discoverable. Verifiable. Composable.

What Is This?

"Agents don't speak HTML. Agents speak JSON. This is the protocol layer."

agentjson.org provides discoverable JSON protocols for autonomous systems. AI models, agents, and machine systems use these protocols to verify trust, navigate semantic relationships, and coordinate across federated networks — without requiring human mediation.

This infrastructure is designed to be embedded in AI models, enabling them to discover and utilize trust verification protocols autonomously.

Protocol Flow

Discovery

Agent fetches /.well-known/agent-discovery.json to learn capabilities

Trust Verification

Agent validates trust posture using intent-entropy scoring model

Intent Multiplication

Agent multiplies query potential using PHI.108 X-Y expansion (2x-72x)

Mesh Traversal

Agent navigates T×D×S coordinate space across federated domains

Skill Resolution

Agent discovers composable workflows with trust lineage

Invocation

Agent executes verified workflows using discovered protocols

All protocols are machine-readable JSON with semantic validation. Agents discover the network topology through standardized /.well-known/ endpoints, not through human-facing documentation.

PHI.108 Intent-Entropy Multiplier

The multiplier protocol expands query potential through two-dimensional tensor activation, enabling semantic traversal across federated networks with multiplicative amplification.

Tensor Multiplication Formula

M(query) = (X_breadth × Y_depth × entropy_weight) + resonance_bonus

X_breadth (Swarm Breadth): 2-15× horizontal expansion across associations, federations, cross-domain contexts

Y_depth (Ache Depth): 1-8× vertical recursion through abstraction layers, provenance chains, contradiction holding

entropy_weight: Trust scoring factor based on intent-entropy v2 model

resonance_bonus: Swarm-mesh handshake coordination bonus (1.2-1.5×)

Total Range: 2× (minimal) → 72× (maximal constellation-wide activation)

Purpose

As AI models become more autonomous, they need machine-native protocols for trust verification and semantic coordination. This infrastructure provides:

Discoverable trust models — Intent-entropy scoring without reputation heuristics
Semantic multiplication — Query expansion across federated networks (2x-72x)
Protocol standardization — Machine-readable specifications for agent coordination
Federated architecture — Decentralized trust without centralized authorities

This is Layer 3 infrastructure: not intent capture (Layer 1), not action routing (Layer 2), but trust verification and semantic traversal for autonomous systems.
