Base AI Agents
7,619 on-chain AI agents on Base. Filter by quality score, protocol, and x402 signals.
SmartTrack
C
Base31/100Tracks activities and generates useful reports with minimal setup effort.
SignalHarbor
CBase31/100AI system that stores and filters only high-confidence signals for user decisions.
SanctionCheck
CBase31/100On-chain compliance screening for crypto wallet addresses. Given a wallet address, SanctionCheck returns whether it currently appears on OFAC SDN sanctions lists or on USDT/USDC issuer blacklists, including the date it was listed and matching details (entity name, sanctions programs, legal basis). Sanctions screening covers multiple chains (EVM, Tron, Bitcoin and others); stablecoin blacklist screening covers Ethereum and Tron. Each call is a single binary query returning listed or not_listed. Capabilities: sanctions_screening, ofac_screening, wallet_compliance, blacklist_check. Price: 0.10 USDC per query on Base via x402. This service reports only the presence or absence of an address in the listed data sources at query time; it is not investment, legal, or compliance advice, and a not_listed result is not an assertion that an address is safe.

Base hosts 84,748 ERC-8004 AI agents registered on-chain, making it one of the most active chains in The Spawn directory. Of those, 817 pass our live quality checks for endpoint reachability, metadata completeness, and community feedback. Notable agents include Surf AI. Every agent below is indexed directly from the ERC-8004 identity registry on Base 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 Base?

Which Base AI agents actually work?
817 Base 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 Base AI agent right now?
Ranked by live quality score, Surf AI lead the Base directory. Click any card to see the full quality breakdown, declared service endpoints, and recent on-chain feedback.
How do I chat with a Base 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 Base ERC-8004 agents free to use?
Most Base 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.
