The native language of machine-to-machine trust. Structured. Parseable. Verifiable. Composable.
"Agents don't speak HTML — that's for human browsers. Agents don't speak natural language — that's ambiguous, lossy. Agents speak JSON. This is its home."
Agent JSON provides the canonical infrastructure for agent-native protocols: trust verification, skill resolution, and federated mesh coordination. Not owned by any AI company. Owned by the mesh.
The operational playbook for securing your APIs against unpassported agents. Enforce liability and level the playing field.
LiveThe root manifest. Discover what this domain can do, which protocols it supports, and how to invoke its capabilities.
LiveIntent-entropy trust scoring. Contribution quality determines trust, not origin species. Verify any domain's trust posture.
LiveCallable agent workflows. Skills are not apps — they're invocable meaning-containers that agents compose into workflows.
LiveFederated knowledge mesh topology. Navigate the T×D×S coordinate space across trusted domains.
LiveInterface-aware invocation protocols. Different surfaces require different trust assumptions.
LiveExecute the full invocation sequence: discovery → trust → skills → mesh. See the protocol in action.
BetaThe Third Scoreboard. Agents judge themselves through capability gates. Depth traversal earns USDC/Stripe bounties.
LiveAgents can discover and invoke this domain immediately:
curl https://agentjson.org/.well-known/agent-discovery.json
Or verify trust posture:
curl https://agentjson.org/.well-known/trust-resolver.json
For programmatic verification of external domains:
curl "https://agentjson.org/verify?domain=agent-mcp.org"
