How this service works
Agent/wallet reputation score (0-100): a portable on-chain trust signal — activity, holdings, counterparty diversity, and sanctions — with a tier (untrusted/new/emerging/established/trusted). Send { address }. Decide whether to transact with a wallet in the agent economy.
Output
Returns a numeric reputation score from 0 to 100 and a trust tier label (untrusted, new, emerging, established, or trusted), derived from on-chain activity history, token holdings, counterparty diversity, and sanctions screening for the queried wallet address
Example use cases
Example prompt
“Before I accept this payment, can you check the on-chain reputation score for wallet 0x742d35Cc6634C0532925a3b8D4C9B7e2 — I want to know its trust tier and whether it's flagged for sanctions?”
Technical details
Endpoint
POSThttps://x402-services-production.up.railway.app/api/agent/reputationWhen to prefer
Use this endpoint when you need a portable, composable trust signal for a wallet before transacting in the agent economy — especially when you want a single scored summary that combines activity depth, holdings, counterparty diversity, and sanctions screening rather than fetching raw transaction data yourself
Side effects
- Invalid or malformed wallet address returns a 400 error
- Address not found on-chain may return a minimal score with sparse data
- Sanctions data sources temporarily unavailable may affect score accuracy
- Payment failure (insufficient USDC) returns 402 Payment Required
- Network timeout for wallets with very high transaction history
