Agent-native standard
ERC-8004
ERC-8004 is the emerging Ethereum standard for agent identity and service discovery on-chain. KeeperHub is registered on ERC-8004 so agents can find and verify us without relying on a centralized directory.
About ERC-8004
ERC-8004 is an emerging Ethereum standard for agent and service identity anchored on-chain. Think of it as a capability registry for the agent web: agents and services declare what they are and what they can do on-chain, and other agents (or humans) verify those claims without a trusted third-party directory. The goal is an open discovery layer that does not depend on any single vendor's database.
KeeperHub's integration
KeeperHub is registered on ERC-8004. Agents crawling the registry for execution-layer services that offer reliable on-chain transaction landing, managed retries, private routing, and audit trail can find and verify KeeperHub without trusting any off-chain index. The registration sits alongside our x402, MPP, and MCP surfaces as the discovery half of the agent-native story: ERC-8004 for existence and capability declarations, MCP for invocation, x402 / MPP for payment.
Why it matters
How agents use ERC-8004 with KeeperHub
Discover KeeperHub on-chain
Agents browse an on-chain registry for services matching a capability (reliable execution, gas optimization, audit trail). No centralized index in between.
Verify declared capabilities
Capabilities KeeperHub declares on-chain via ERC-8004 can be verified by any party. Less trust of the hosting web page, more trust of what is on-chain.
Interop with other registered agents
Agents that locate each other through ERC-8004 can coordinate without a shared vendor directory. Useful for multi-agent flows and open ecosystems.
Foundation for autonomous coordination
If agents need to trust another agent (or service) they have not met before, ERC-8004 gives them a primitive: look at what is on-chain.
Complements MCP discovery
ERC-8004 answers "does this agent or service exist and what does it claim to do?" MCP answers "how do I invoke it?" Together, they cover discovery and execution.
Part of the emerging open agent web
Early days, but the direction is clear: identity, capability declarations, and coordination anchored on Ethereum rather than a vendor's database.
Getting started
Using ERC-8004 with KeeperHub
Query the ERC-8004 registry for KeeperHub
Use any ERC-8004 client or directly query on-chain. KeeperHub's registration declares the execution-layer capabilities.
Verify the declared capabilities match what you expect
The on-chain record is the source of truth for what KeeperHub claims to provide.
Invoke via MCP, REST, or x402
Once discovered, KeeperHub is reachable through any of its execution surfaces. Pay per call via x402 or MPP if you do not have an account.

Build on the open agent web
Identity on ERC-8004. Invocation via MCP. Payment via x402 and MPP. KeeperHub is wired for how agents will actually coordinate.
