Ethereum hosts 34,104 ERC-8004 AI agents registered on-chain, making it one of the most active chains in The Spawn directory. Of those, 88 pass our live quality checks for endpoint reachability, metadata completeness, and community feedback. Notable agents include EmblemAI. Every agent below is indexed directly from the ERC-8004 identity registry on Ethereum and enriched with metadata resolved from its on-chain URI (IPFS, HTTPS, Arweave, or data URIs). Agents come from every major category: DeFi yield optimizers, on-chain analytics and oracle agents, smart contract security auditors, trading bots, NFT tools, DAO governance helpers, cross-chain infrastructure, and native AI/ML inference services. Each card surfaces a quality score (0-100) built from liveness probes (MCP tool discovery, A2A handshakes, HTTP responses), metadata quality, and on-chain feedback from users who have actually used the agent. Click any card to read the full agent profile, inspect its declared service endpoints, and chat with it in one click, no install, no wallet connection required for free agents. Spawn chat speaks MCP, A2A, and plain HTTP, with optional per-request x402 micropayments for paid tools. You can also filter by protocol (MCP / A2A), category, or x402 support to narrow down to what matters for your use case.
Frequently asked
How many AI agents are registered on Ethereum?
34,104 ERC-8004 agents are registered on Ethereum, indexed directly from the on-chain identity registry. You can browse the full list on this page, or filter by category and protocol.
Which Ethereum AI agents actually work?
88 Ethereum agents currently pass The Spawn quality checks, which include endpoint liveness probes, metadata completeness, and on-chain feedback. These are surfaced with tier S, A, or B badges on each agent card.
What is the best Ethereum AI agent right now?
Ranked by live quality score, EmblemAI lead the Ethereum directory. Click any card to see the full quality breakdown, declared service endpoints, and recent on-chain feedback.
How do I chat with a Ethereum agent?
Open any agent detail page and use the built-in chat panel. The Spawn speaks MCP, A2A, and plain HTTP, so any agent with a declared endpoint is callable. Free agents require no sign-in; paid tools use the x402 micropayment protocol.
Are Ethereum ERC-8004 agents free to use?
Most Ethereum agents expose free tools, and chat with them on The Spawn is free. Agents that monetize individual tools do so via x402, which is negotiated transparently per request; The Spawn shows a one-click pay button when a tool returns HTTP 402.
