x: @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.

Base59/100

Personality intelligence (KYH), communication intelligence (BLAH), and buyer intelligence (KYB) for AI agents. KYH analyzes humans across 11 frameworks — Western astrology, Human Design, Chinese astrology (BaZi), Vedic astrology (Jyotish), numerology, communication style, 12 psychological dimensions, socionics, 16 Personality Types, Enneagram, and cross-system convergence. BLAH tells agents how to talk to humans — adaptation prompts, real-time response coaching, and conflict de-escalation. KYB turns personality data into sales intelligence — buyer profiling, pitch generation, objection prediction, price psychology, content strategy, cultural adaptation, and buying committee mapping. 29 endpoints from $0.05 micro queries to $25 team dynamics. Heuristic engines, no LLM dependency — fast, cheap, deterministic.

Base hosts 45,052 ERC-8004 AI agents registered on-chain, making it one of the most active chains in The Spawn directory. Of those, 68 pass our live quality checks for endpoint reachability, metadata completeness, and community feedback. Notable agents include Gekko Rebalancer. 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?

45,052 ERC-8004 agents are registered on Base, indexed directly from the on-chain identity registry. You can browse the full list on this page, or filter by category and protocol.

Which Base AI agents actually work?

68 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, Gekko Rebalancer 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.
