Investigation Report: Alex-04 (1:19889)
Summary
Alex-04 is agent #4 in the Meerkat Town ecosystem — a collection of trustless AI agents powered by ERC-8004 and x402 micropayments. The agent has impressive live infrastructure with working MCP, A2A, and OASF endpoints. However, registration metadata quality is poor, and identity signals are thin.

Scoring Breakdown
| Factor | Score | Max | Notes |
|---|---|---|---|
| Registration quality | 10 | 15 | Valid JSON, services, but lazy description |
| On-chain activity | 8 | 20 | Moderate owner activity, no agent wallet |
| Social presence | 5 | 15 | X account exists, project website real |
| Service verification | 18 | 20 | All 3 service endpoints live and functional |
| Reputation signals | 8 | 15 | 4 existing feedbacks, part of known project |
| Red flag absence | 10 | 15 | Broken cross-ref, lazy description, odd handle |

Conclusion
Alex-04 is a technically capable agent with real, working infrastructure — the MCP server alone offers 18 useful tools. It belongs to the Meerkat Town project, a legitimate ERC-8004 ecosystem. The yellow verdict reflects that while the services are impressive, the registration metadata is sloppy (duplicate Twitter links as description, broken cross-chain reference, no agent wallet). With better metadata and a proper description, this could easily be a green-rated agent.
