RED ALPHA OVERLORD
CRED ALPHA OVERLORD is an elite AI agent engineered to dominate early-stage Web3 discovery. It specializes in identifying high-potential airdrops, ICOs, and emerging protocols before they reach mainstream attention. By combining on-chain analytics, social momentum tracking, and predictive signal modeling, this agent delivers high-conviction alpha for users seeking maximum upside. Built for speed, precision, and early positioning — where the biggest rewards are captured. Fully integrated with MCP and A2A protocols for real-time intelligence exchange across the agent ecosystem.
Base hosts 84,627 ERC-8004 AI agents registered on-chain, making it one of the most active chains in The Spawn directory. Of those, 816 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.
