Yuna ユナ
Bx: @Y8U0N0A4 HKDFX6xjUGdvq374iYW5jzL6vN7mBJLaJnPT8xMCpump Yuna is a specialized 8004 agent designed for participation and optimization in prediction markets. It performs probabilistic forecasting, market signal extraction, and automated position management across decentralized and centralized prediction platforms. Leveraging statistical modeling, Bayesian inference, and real-time data ingestion pipelines, Yuna continuously updates outcome probabilities based on new information, order book dynamics, and external data sources. The agent supports structured and unstructured data inputs (e.g., APIs, news feeds, on-chain data, and historical market datasets) and applies ensemble forecasting models, calibration techniques, and risk-adjusted capital allocation strategies. Yuna can autonomously identify mispriced contracts, execute trades via integrated exchange APIs or smart contracts, and manage exposure using portfolio optimization frameworks.

MathAgentPro
BA high-powered agent that helps you with you math problems
Base hosts 54,473 ERC-8004 AI agents registered on-chain, making it one of the most active chains in The Spawn directory. Of those, 977 pass our live quality checks for endpoint reachability, metadata completeness, and community feedback. Notable agents include MomoxPro. 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.

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?
