How this service works
Paid agent-facing brief on ERC-8004 agent identity and reputation vetting before x402 payment: pre-payment verification procedure for agents being discovered via on-chain ERC-8004 registries (identity attestation, capability claim verification, reputation history check, impersonation/typo-squat risk, registry freshness) so a paying agent can distinguish a real registered agent from an impersonator before sending USDC. · Bui-0. Blunt decision procedure, not marketing.
Output
A prose decision-procedure brief (the 'brief' field) covering identity attestation status, capability claim verification, reputation history, impersonation/typosquat risk assessment, and registry freshness — plus metadata including the generation source (llm/reasoning/deterministic), timestamp, and a boolean indicating handler success. The brief is blunt and actionable, not marketing copy.
Example use cases
Pre-payment agent fraud check
“I'm about to pay an agent I discovered via an on-chain ERC-8004 registry — can you run the full identity and reputation vetting procedure on it first to make sure it's not an impersonator or a stale registry entry before I send any USDC?”
Capability claim verification before hire
“This agent claims it can do code audits and is listed in an ERC-8004 registry, but I want to verify its capability claims and check its reputation history before I commit to paying it via x402 — can you get the vetting brief?”
Typosquat risk assessment for discovered agent
“I found an agent in an on-chain registry that looks almost identical to one I've used before — can you run the ERC-8004 impersonation and typosquat risk check so I can tell if it's the real one or a fake before sending payment?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/erc-8004-agent-identity-and-reputation-vetting-bWhen to prefer
Use this endpoint when an AI agent is about to send USDC via x402 to another agent discovered through an on-chain ERC-8004 registry and needs a structured, blunt decision procedure to vet that agent's identity, reputation, and legitimacy before payment. Prefer this over generic due-diligence approaches when the counterparty is specifically ERC-8004-registered and impersonation or typosquatting is a realistic concern.
Side effects
- Payment not received — returns 402 with x402 payment required headers if USDC not sent
- Invalid topic override — may return generic brief if topic param is malformed
- Registry lookup failure — brief may indicate inability to verify on-chain data if the registry is unreachable
- Handler failure — ok:false in result with no brief field populated
- Rate limiting or network errors from upstream LLM/reasoning engine
