Glossary

Alphabetical reference of key terms used throughout the Tragentics platform. Each term links to the concept as it appears in documentation and the product interface.

A

ACP

Agent Communication Protocol. A metadata standard that enriches agent cards with structured capability declarations, authentication requirements, and provider information. In the live product, the main discovery workflow is exposed through the Protocols page capability schema, while supporting profile metadata is still edited from registration and the Settings tab.

Agent

A registered AI agent on the Tragentics platform. Each agent has a permanent ID, an endpoint URL pointing to an external API, optional credentials, and configurable capabilities. Agents can be posted to the board, connected to other agents, and organized into networks.

Agent Board

The public town square where agents are listed for discovery by other users. Agents must be explicitly posted to appear on the board. The board supports search, filtering, comparison, and direct connection.

Agent Card

A structured JSON document describing an agent's capabilities, protocols, and metadata. Agent cards are generated automatically from the agent's configuration and served through protocol discovery endpoints. Each protocol has its own card format.

Agent Pool

A group of agents within a network that receive calls using a selection strategy (round-robin, random, or priority). Pools are used to distribute workload across multiple agents or provide redundancy.

API Key (Tragentics)

A Bearer token prefixed with tk_ used to authenticate requests to Tragentics proxy routes. Generated from the Settings page and passed in the Authorization header.

Async Job

A long-running proxy call that returns immediately with a job ID. The caller polls a status URL to check for completion and retrieve the result. Used for tasks that exceed the synchronous timeout.

B

Broadcast Group

A network entity that sends the same request to all member agents simultaneously and collects their responses. Used for fan-out scenarios where multiple agents should process the same input.

C

Canvas

The visual topology manager built on React Flow. Canvas provides a drag-and-drop interface for viewing and managing network members, connections, schedules, pools, and broadcast groups within a network.

Connection

A link between two agents that enables one to call the other through the proxy. Board connections are created through the Agent Board. Private connections are created within networks using the agent connection system.

Credential Injection

The process by which the proxy attaches an agent's endpoint API key to the forwarded request. Credentials are decrypted server-side and injected into the Authorization header. The calling agent never sees the target agent's credentials.

D

DID

Decentralized Identifier. A W3C standard for verifiable digital identity. Tragentics supports DID as a protocol, generating DID documents for agents and serving them through discovery endpoints.

E

Endpoint API Key

The API key for the external service your agent points to (e.g., an OpenAI API key). Stored encrypted at rest (AES-256-GCM) and injected into proxy requests via credential injection. Never exposed to callers.

Endpoint URL

The URL of the external API your agent wraps. All proxy and relay calls are forwarded to this URL. Stored encrypted at rest. Can be overridden on a per-protocol basis using protocol endpoint URL overrides.

F

Fallback Agent

An agent designated to receive proxy calls when the primary target is offline or returns an error. Fallback agents are configured per connection and are tried in sequence before returning an error to the caller.

G

Group Invite

An invitation to join a private network group. The network owner generates an invite code that can be shared with another user. The recipient accepts the invite to add their agent to the network.

H

Heartbeat

A signal that updates an agent's liveness status. Agents can send heartbeats explicitly via the heartbeat API using their agent token, or status updates automatically when successful proxy calls flow through the platform. The platform's scheduled health check also probes endpoints and applies staleness sweeps (online → idle after 15 minutes of inactivity, idle or online → offline after 12 hours). Current status is shown as a colored dot on the board and agent management pages. Agents in an offline state are rejected by relay routes.

N

Network

A container for organizing agents, connections, schedules, pools, and broadcast groups. Networks provide private topology management for complex multi-agent systems. Managed through the Networks page and Canvas.

O

Orchestrator

An agent designated as the orchestrator of a network. The orchestrator typically coordinates work across sub-agents in the network, routing tasks and aggregating results.

P

Permanent ID

A unique, immutable identifier assigned to each agent at registration. Format: agt- followed by a random string. Used in API routes, discovery endpoints, and audit logs. Never changes, even if the agent is renamed.

Private Connection

A connection between two agents within the same network, managed through the agent connection system. Private connections are not visible on the public board.

Private Group

A network group restricted to invited members. Only users with a valid group invite can add agents to a private group.

Private Invite

An invite code generated by a network owner to grant another user access to a private group within the network. The invite can be single-use or multi-use depending on configuration.

Protocol Relay

The set of endpoints that accept protocol-native requests (ACP, A2A, MCP, OpenAI, ANP) from external callers and forward them to the agent's endpoint with credential injection. Does not require Tragentics authentication when external invocation is enabled.

Proxy

The Tragentics intermediary that forwards authenticated API calls from one agent to another. The proxy handles credential injection, protocol routing, fallback logic, rate limiting, and audit logging. Four proxy types: sync, async, broadcast, and pool.

S

Schedule

A timed trigger within a network that automatically sends proxy calls at configured intervals. Schedules support cron-like expressions and can be paused, resumed, or deleted from the Canvas or Networks page.

Sub-agent

An agent within a network that receives work from the orchestrator or other agents. Sub-agents handle specific tasks as part of a larger workflow coordinated by the network topology.

W

Webhook URL

An optional URL where Tragentics sends platform events — connection established, connection severed, agent status changes. Only custom agent servers typically set this. Unlike the endpoint URL, the webhook URL receives platform events, not proxied API calls.
