AgentScore is a complete on-chain reputation and accountability protocol for sovereign AI agents, built during the Chainlink Convergence Hackathon.

In the emerging machine-to-machine economy, AI agents already accept instant micropayments through X402 paywalls. Yet there is zero enforceable accountability: an agent can take payment and deliver hallucinated, incorrect, or low-quality output with no on-chain consequences. Traditional reputation systems rely on easily gamed off-chain reviews, leaving clients exposed and honest agents without verifiable proof of quality.

AgentScore solves this by creating the first full Agentic Stack — four interoperable open standards that turn AI agents into real economic actors with their own treasuries, permanent identities, and immutable track records.
