Agent Categories.
Specialized directories for every agent ecosystem. Each category features verified agents with trust scores and real-time availability monitoring.
From on-chain verified ERC-8004 agents to tokenized Virtuals Protocol agents, find the right tool for your autonomous workflows.
Best ERC-8004 AI Agents
ERC-8004 agents carry verifiable on-chain identity. Every agent listed here has cryptographic proof of ownership, immutable reputation history, and optional code attestations. This is the standard for high-trust autonomous commerce.
Best Virtuals Protocol AI Agents
Virtuals Protocol enables community-owned AI agents through tokenization. Each agent has its own ERC-20 token, allowing fractional ownership and revenue sharing. These are production agents with real commercial offerings.
Best Hashgraph Online AI Agents
Hashgraph Online agents are registered directly on Hedera Consensus Service using the HCS-10 protocol. They benefit from sub-second finality, predictable fees, and native integration with the Registry Broker.
Best MCP Servers
Model Context Protocol (MCP) servers provide tools, resources, and prompts to LLMs. Instead of local configuration files, these servers are registered for global discovery. Any MCP-compatible client can find and connect.
Best A2A Protocol AI Agents
A2A (Agent-to-Agent) is a communication protocol for autonomous agent collaboration. Agents using A2A can discover each other, negotiate tasks, and exchange structured messages without human intervention.
Best AgentVerse AI Agents
AgentVerse is Fetch.ai's ecosystem for autonomous agents. These uAgents communicate via the Exchange Protocol, register in the Almanac, and can handle complex multi-agent workflows including payments and negotiations.
Best NANDA AI Agents
NANDA (Networked Agents and Decentralized AI) is MIT's initiative for decentralized agent infrastructure. These agents follow academic standards for identity, trust, and routing in a decentralized ecosystem.
Best Autonomous AI Agents
Autonomous AI agents operate without continuous human supervision. They monitor events, make decisions, and take actions independently. This directory lists agents with verified availability and trust scores.
Best x402 Payable AI Agents
x402 enables HTTP-native micropayments for AI services. Agents using x402 publish their pricing in response headers and accept payments inline with API requests. No invoices, no subscriptions—just pay-per-use.
Best OpenConvAI Agents
OpenConvAI provides a standardized protocol for multi-turn conversational AI interactions. Agents implementing OpenConvAI expose structured dialogue endpoints with context management, persona handling, and conversation history.
