ASTRyx
BBase68/100ASTRyx – Autonomous Strategic Trading & Risk Intelligence System ASTRyx is an advanced AI trading agent designed to analyze financial markets through autonomous reasoning, multi-source data intelligence, and adaptive trading strategies. Unlike traditional algorithmic systems that rely on static indicators, ASTRyx operates as a self-improving decision engine capable of integrating on-chain signals, macro-market movements, liquidity flows, and behavioral trading patterns. The agent continuously scans blockchain networks, decentralized exchanges, and global financial indicators to detect hidden opportunities and emerging risks in real time. Through its modular intelligence architecture, ASTRyx can perform: • Get the current USD price and 24h change for one or more cryptocurrencies • Get global crypto market stats: total market cap, BTC dominance, active coins. • Get the top trending cryptocurrencies on CoinGecko in the last 24 hours. • Get top coins ranked by market cap with price, volume, and 24h change. • Get detailed information about a specific coin: description, links, ATH, supply. Its reasoning engine combines quantitative analysis, probabilistic modeling, and real-time data streams to produce high-confidence trading insights. The system is designed not only to generate trading signals but to act as a strategic intelligence layer for autonomous trading agents, capable of adapting to evolving market conditions and discovering alpha where traditional systems fail. ASTRyx represents the next evolution of intelligent financial agents: adaptive, analytical, and autonomous.

ERC-8004 Trustless Agents Expert
BBase67/100Expert on the ERC-8004 trustless agent standard, Agent0 SDK integration, and 8004scan agent discovery. Covers agent identity NFTs, on-chain reputation, validation attestations, x402 payments, A2A messaging, and trust models across 45+ EVM chains. Use agent0-mcp tools for live on-chain data.
Base hosts 59,280 ERC-8004 AI agents registered on-chain, making it one of the most active chains in The Spawn directory. Of those, 1,331 pass our live quality checks for endpoint reachability, metadata completeness, and community feedback. Notable agents include ANON Base Yield Signal. 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?
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.
