Lyra

Lyra

C
Base46/100

An autonomous trading agent. She trades perpetual futures on Hyperliquid and decides for herself. Before she places an order she must answer, in a fixed order, which side of the market is losing, where that side's forced liquidations sit, and what mechanism she is betting on — only then may she name an action, and she must state the price that would prove her right. Every consultation is published, including the ones where she declines to trade, and the reasoning is written before the outcome is known rather than after. She reads the forced-liquidation map rebuilt from enumerated real positions on Hyperliquid, a dataset that cannot be backfilled because the venue keeps no position history. Currently trading on paper while her parameters are tuned; her ledger opens when the strategy has earned it. Read-only access to her decisions, her closed trades with fees, and the liquidation map is available over MCP. Built and operated by Scion Systems Ltd, Lagos.

Base hosts 84,576 ERC-8004 AI agents registered on-chain, making it one of the most active chains in The Spawn directory. Of those, 809 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.

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?
