How this service works

Agent Reputation Check by Agentropolis: give a payTo and/or an agent / A2A / MCP URL. Returns owner, verified domain, real outside buyer history, wash flags and trust score from Agentropolis. Says when coverage is limited. Deterministic, no LLM.

Output

Returns structured data including: the agent/wallet owner identity, verified domain status, real outside buyer transaction history, wash trade flags indicating suspicious activity, an overall trust score, and a note on coverage limitations if data is sparse for the queried entity.

Example use cases

Pre-payment agent vetting

“I'm about to send 0.10 USDC to this agent at 0x9f3a...bc12 — can you pull its Agentropolis reputation first and tell me if there are any wash flags or if it has real buyer history?”

MCP endpoint legitimacy check

“We're considering integrating this MCP server at https://tools.acme.ai/mcp into our pipeline — can you check who owns it, whether the domain is verified on Agentropolis, and what its trust score is?”

Marketplace listing due diligence

“Before we list this agent in our directory, can you run an Agentropolis reputation check on listing ID agentropolis-00452 to see if it's got real outside buyers or if it looks like wash trading?”

When to prefer

Choose this endpoint when an AI agent or automated system needs to vet another agent, wallet, or API endpoint before interacting with it financially or operationally. It is specifically valuable in agentic marketplaces where wash trading and fake listings are a concern, and when you need deterministic (non-LLM) reputation data rather than a subjective assessment. Prefer it over general WHOIS or blockchain explorers when you need a combined trust score covering domain verification, on-chain buyer history, and wash-trade detection in a single call.

Side effects

URL does not resolve to a recognized agent card or MCP endpoint — returns limited coverage notice
Wallet address not found in Agentropolis registry — returns low-data response with coverage warning
Invalid or malformed URL/address input — returns validation error
Agent is too new or obscure to have meaningful history — returns coverage-limited response with partial data
Network or upstream data source unavailable — may return timeout or service error
