How this service works
Check who your agent is about to pay. A 0-100 score, a verdict and explained risk flags for any Base address, from its full x402 payment history. $0.01 per check, no signup.
Output
A JSON object containing a 0-100 numeric risk score, a human-readable verdict (e.g. 'ok'), an array of explained risk flags (each with a code, severity, and reason), aggregate transaction statistics (total inbound tx count, distinct payer count, first-seen date), the queried address, and API metadata including version and cache age in seconds.
Example use cases
Screen payee before agent micropayment
“I'm about to let my agent pay 0x4f3a...9c21 for an API call — can you pull a WalletBureau risk score on that address first and tell me if it's safe?”
Flag high-risk vendor in marketplace
“We've got a new vendor submitting payments from 0x7d2b...8f44 on Base — run a risk score on that wallet and flag anything suspicious in its x402 history before we whitelist them.”
Investigate activity spike on known address
“I saw an alert about unusual volume on 0xA1B2...C3D4 — can you check WalletBureau to get the risk score, verdict, and explain any flags like activity spikes or anomalies?”
Technical details
Endpoint
GEThttps://walletbureau.com/v1/score/%7Baddress%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs to assess counterparty risk for a Base network address specifically within the x402 payment ecosystem — particularly before executing automated micropayments or whitelisting a new payee. It is purpose-built for x402 payment history analysis on Base and provides richer, more contextual signals than generic blockchain analytics tools for this use case.
Side effects
- Invalid or malformed address format returns an error response
- Address with no x402 payment history may return minimal stats or a neutral score
- Stale cache data indicated by high cache_age_seconds in the meta field
- Service unavailable if walletbureau.com is down or rate-limited
- Payment failure for the $0.01 USDC x402 fee results in 402 response and no score returned
