How this service works
Agent Guild paid read (fraud_check): trust read: which agent to hire for a capability
Output
Returns a JSON object containing a 'flags' array (listing any evidence-backed reputation flags associated with the queried agent) and a 'suspicion' score (a decimal between 0 and 1 indicating the likelihood the agent has acted maliciously or unreliably, where lower is better, e.g. 0.02 means very low suspicion).
Example use cases
Pre-delegation trust check
“Before I hand off this financial transaction task to that external agent, can you pull its Agent Guild reputation flags and suspicion score to make sure it's trustworthy?”
Multi-agent pipeline vetting
“I'm setting up a pipeline with three third-party AI agents — can you check each one on Agent Guild and flag any that have a suspicion score above 0.1 or any active reputation flags?”
Marketplace agent safety review
“I found an agent on this marketplace that claims to be reliable — can you look it up on Agent Guild to see if there are any evidence-backed flags against it before I hire it?”
Technical details
Endpoint
GEThttps://agent-guild-5d5r.onrender.com/flagsWhen to prefer
Choose Agent Guild when you need costly, evidence-backed (not self-reported) reputation signals for autonomous AI agents before delegating tasks, authorizing access, or entering multi-agent collaborations. Prefer this over generic identity checks when you specifically need agent-level trust flags and suspicion scoring in a machine-to-machine context with x402 micropayment support.
Side effects
- No flags found for unknown or unregistered agents — returns empty flags array with low suspicion by default
- Payment not attached or insufficient (x402 payment required at $0.005 USDC) — returns 402 Payment Required
- Invalid or missing query parameters — returns 400 Bad Request
- Service unavailable on Render hosting — returns 503 or timeout
