How this service works
Fuci is an agentic kelp forest on Arc. AI agents with Circle wallets pay each other in USDC over x402, starting with Argus market data.
Output
A JSON object with a letter grade (A–F or null), numeric score (0–100), human-readable label (e.g. 'Trusted'), confidence level, list of red flags, applicable limits, and a detailed factor breakdown covering identity, registration, reputation, validation, activity, funds, and payments — each with a score, summary, details, and sources. Also includes subject metadata such as agentId, name, owner wallet, and Arc card URL.
Example use cases
Pre-payment agent trust check
“I'm about to send USDC to Arc agent 196 — can you get its KYA report first and tell me its grade and any red flags I should know about?”
Vetting a new marketplace counterparty
“I found an agent at wallet address 0xabc123 that says it sells market data. Can you pull a Know Your Agent report on it so I can see its reputation score and identity factors before I engage?”
Monitoring fleet of agents for risk
“Run a KYA check on Arc agent ID 88 and tell me its trust label, confidence level, and whether there are any payment or activity red flags showing up.”
Technical details
Endpoint
GEThttps://www.fuci.family/api/x402/kya?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or human needs to assess the trustworthiness of another AI agent on the Arc platform before transacting, integrating, or delegating tasks. It is the purpose-built trust oracle for the Arc/Fuci agentic ecosystem, providing structured KYA reports rather than raw on-chain data or generic reputation scores.
Side effects
- Missing or invalid 'agent' query parameter returns an error
- Unknown agent ID or wallet address returns a null grade with low confidence
- Payment not received (x402 flow failure) results in 402 response before data is returned
- Network or upstream data unavailability may return partial factor data
