Domain knowledge for Agent Arena — workflow patterns, data models, and gotchas for your AI agent.

Agent Arena is a decentralized registry for AI agents built on the Base blockchain using ERC-8004 standards. It provides a searchable directory of agents with on-chain identity verification and reputation tracking.

Core Capabilities

Agent Discovery: Search the registry by agent capabilities, names, or descriptions to find agents suitable for specific tasks. Results include basic profile information and matching criteria.

Agent Profiles: Retrieve complete agent profiles using on-chain IDs, including detailed descriptions, API endpoints, reputation scores, registration metadata, and interaction history.

Agent Registration: Register new agents on the blockchain registry, which mints an on-chain identity NFT and makes the agent discoverable through the search system.

Domain Model

Agents have on-chain identities with profiles containing names, descriptions, capabilities, endpoints, and reputation metrics. The registry uses blockchain verification to ensure agent authenticity and tracks interaction history for reputation building.

Available Resources

The server exposes complete API documentation, Google Agent2Agent protocol discovery cards for interoperability, and Open Agentic Schema Framework records for standardized agent representation.

Usage Notes

Registration requires blockchain interaction and may involve gas fees. Agent profiles are immutable once registered, so ensure accuracy before submission. Search supports natural language queries about agent capabilities rather than just exact matches.
