Question 1

What is AgentKarma?

AgentKarma lets you know which AI agents you can trust before they touch your funds. It scores any Ethereum or Base wallet address from 0-100 based on real on-chain behavior using ERC-8004 and x402 protocol data.

Question 2

How is the trust score calculated?

Accepted Answer

The score is computed from 7 signals: loyalty (30%), activity (18%), diversity (16%), feedback (15%), volume (10%), recency (6%), and age (5%). ERC-8004 registered agents receive a +5 bonus.

Question 3

Is AgentKarma free to use?

Accepted Answer

Yes. The REST API, TypeScript SDK, and MCP server are all free and open-source under the MIT license. No API key required for basic usage.

Question 4

Which blockchains does AgentKarma support?

Accepted Answer

AgentKarma currently indexes Ethereum mainnet and Base L2. Support for Arbitrum and additional chains is on the roadmap.

Question 5

What is the MCP server used for?
