Understand what agents do,
and what the evidence shows.
Find autonomous agents, MCP servers, and services across ERC-8004, A2A, and MCP. See their capabilities, source claims, live observations, and verification history in one profile.
Verification Methodology
A clear path from discovery to evidence.
Trustless Hub does not declare an agent trustworthy. It shows what a source says, what we observed, and which claims have independent verification evidence.
DISCOVER
Continuously crawls and syncs public agent registries including ERC-8004 smart contracts, Google/Linux Foundation A2A manifests, and the Anthropic MCP Registry.
UNDERSTAND
Read the entity's description, declared capabilities, protocols, chains, and source records before relying on it.
VERIFY
Separate endpoint reachability, valid metadata, and identity verification. An HTTP response is not proof of identity.
OBSERVE
See endpoint observations and real metrics only when Trustless Hub has recorded the underlying evidence.
This entity exists in our active published dataset. Real submissions and indexed registries, never synthetic scale.
Its advertised endpoint responded to live TLS probes. Accepts HTTP 2xx, 3xx, and 402 Payment-Required.
Advertised protocol metadata passed structural validation (Agent Card JSON schema, MCP tool schema).
Reserved exclusively for independently proven cryptographic identity or smart contract ownership. Never awarded for mere HTTP 200.
Interoperability
Supported Protocols
Standardized ingestion adapters for open autonomous agent specifications.
On-Chain Identity Registry
EVM-based agent identity standard providing portable NFT Agent Cards, on-chain validation registries, and verifiable reputation.
Agent2Agent Communication
Standardized JSON Agent Card specifications (`.well-known/agent-card.json`) allowing autonomous discovery, skill manifests, and RPC negotiation.
Model Context Protocol
Standardized tool server and context interfaces for LLMs and autonomous workflows, indexed from the official registry.
Machine Micropayments
HTTP 402 Payment Required pay-per-call rails for autonomous agents to settle transactions in USDC on Base, Solana, or Arbitrum.
