How this service works
Composite 0-100 reputation score for any Base wallet. POST {wallet, days?=90}. Combines ERC-8004 registration (Agent0 subgraph), USDC settlement velocity (Base RPC scan), and ERC-8004 feedback+validation registry events aggregated across all of the owner's agents. Hard-gates on 8004 registration to filter burn addresses + CEX wallets. Cached 24h. Use for: should I integrate/pay/trust this peer agent.
Output
Returns a tiered reputation score (e.g. bronze/silver/gold) for the queried wallet, with supporting evidence including ERC-8004 registration status, IPFS metadata signals, recent payment activity, and aggregated feedback indicators for the requested trailing window.
Example use cases
Vetting agents for task delegation
“Before I delegate my customer support tasks to this agent at 0x9f2d5a1e...c3b8, can you pull its reputation score for the past 90 days? I need to know if it's trustworthy enough and what its recent payment history looks like.”
Evaluating peer agent networks
“I'm building a marketplace where agents collaborate. Can you check the reputation tiers for these three wallet addresses over the last 60 days and show me which feedback signals matter most for each one?”
Risk assessment before fund routing
“I'm about to route funds to this agent wallet for a contract execution. Can you score its on-chain reputation using ERC-8004 and IPFS data, and tell me what tier it lands in so I know how much to trust it?”
Technical details
Endpoint
POSThttps://graphadvocate.com/agent/scoreWhen to prefer
Choose this endpoint when you need to assess the trustworthiness or activity level of an on-chain AI agent wallet before interacting with it, delegating funds, or routing tasks. It is specifically designed for ERC-8004 registered agents and combines registration, IPFS metadata, payment history, and feedback into a single tiered score — making it more comprehensive than raw on-chain balance checks or simple transaction history lookups.
Side effects
- Wallet address not registered under ERC-8004 — returns low score or unranked tier with missing registration evidence
- IPFS metadata unavailable or unresolvable — partial score with missing metadata signals
- No recent payment activity in the trailing window — score reflects inactivity
- Invalid wallet address format — returns 400 error
- Trailing window parameter out of allowed range — returns 422 validation error
- Network or upstream IPFS timeout — returns 503 or partial response
