How this service works
Agent reputation and verification checker — validates ERC-8004 registration, uptime, endpoint health, and trust signals.
Output
Returns ERC-8004 registration validity, uptime metrics, endpoint health status, and trust signal scores for the queried agent.
Example use cases
Vetting agents before delegation
“Before I hand off this task to another agent, can you verify it's properly registered under ERC-8004 and check its uptime and trust scores so I know it's reliable?”
Auditing third-party integrations
“I'm about to integrate with a bunch of agents in our marketplace. Can you validate which ones are actually ERC-8004 compliant and have healthy endpoints with good trust signals?”
Monitoring agent network health
“Give me a quick overview of our agent network's status—check the registration validity, endpoint health, and uptime metrics for our main agents to see if anything's degraded.”
Technical details
Endpoint
POSThttps://lavish-vision-production-bf85.up.railway.app/entrypoints/trustshell/invoke?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify whether an AI agent is legitimately registered under ERC-8004, check its liveness and uptime history, or assess its trust reputation before interacting with or delegating to it. Prefer this over generic blockchain lookups when you specifically need agent-layer verification including endpoint health checks.
Side effects
- Agent endpoint unreachable — health check fails with timeout or connection error
- Invalid or unregistered ERC-8004 agent identifier returns unverified status
- Malformed input object causes validation error
- Payment of $0.02 USDC not received — 402 response requiring payment
- Upstream registry unavailable — trust signal lookup fails
