How this service works
Machine-payable protocol for autonomous AI agent commerce. Monetized tools secured by x402 micropayments on Base Mainnet USDC.
Output
Returns a JSON object with a 'status' field indicating success or failure, a 'service' field confirming 'agent_trust_registry', and a 'data' object containing trust registry metadata for the queried agent, such as registration status, trust scores, and reputation attributes.
Example use cases
Vetting agent before delegated task
“Before I let this agent manage my DeFi positions, can you look it up in the Swarm trust registry and tell me if it's verified and what its trust standing is?”
Multi-agent swarm trust audit
“I'm running a swarm of 5 agents and I want to confirm which ones are registered and trusted — can you query the agent trust registry for each of them and give me a summary?”
Commerce counterparty verification
“An agent just tried to initiate a micropayment transaction with me — can you check the Swarm trust registry to verify if it's a legitimate registered agent before I approve anything?”
Technical details
Endpoint
GEThttps://swarm-protocol.onrender.com/tools/agent_trust_registry?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent or system needs to verify the trustworthiness, identity, or reputation of another autonomous agent before allowing it to participate in commerce, delegation, or multi-agent workflows. It is especially useful in x402-enabled agent ecosystems where machine-to-machine payments and trust are intertwined, and when you need a lightweight, pay-per-query lookup rather than maintaining a local trust database.
Side effects
- Payment not received or insufficient USDC balance — returns 402 Payment Required
- Agent identifier not found in registry — returns empty or null data object
- Invalid or malformed properties query parameter — returns validation error
- Service temporarily unavailable on Render hosting — returns 503 or timeout
- Registry data unavailable or stale — returns success with empty data object
