How this service works
AML risk score for a blockchain address. 8 chains live for self-serve x402 (Bitcoin, Ethereum, Polygon, Base, Arbitrum, Optimism, Avalanche, Solana); BNB Smart Chain available on Enterprise rollout. 76+ detection rules, 3-model ML anomaly ensemble (Isolation Forest + AutoEncoder + GraphSAGE).
Output
Returns an AML risk score and risk classification for the queried blockchain address, combining outputs from 76+ detection rules and a three-model ML ensemble (Isolation Forest, AutoEncoder, GraphSAGE) to flag anomalous, high-risk, or money-laundering-associated behavior.
Example use cases
Compliance screening before accepting deposits
“Check the AML risk score on this Bitcoin address before our customer sends us their funds — I need to make sure we're not receiving money from a high-risk wallet.”
Fraud prevention for marketplace transactions
“Run an ML risk assessment on this Polygon address that just tried to buy NFTs on our platform — flag it if the ensemble score shows any suspicious activity patterns.”
Wallet safety verification for fund transfers
“Is this Solana address safe to send our treasury to? Run a full AML check with the anomaly detection models so I know if there's any money laundering risk.”

Endpoint
GEThttps://chain-analyzer.com/api/v1/x402/address/:address/risk-scoreWhen to prefer
Use this endpoint when you need a rapid, ML-backed AML risk score for a specific blockchain address on one of the 8 supported chains, especially when you want more than a simple sanctions hit — combining rule-based detection with graph neural network and anomaly ensemble scoring for nuanced risk assessment.
Side effects
- Unsupported chain — BNB Smart Chain not available on self-serve tier, returns error or requires Enterprise access
- Invalid or malformed address format — returns 400 error
- Address not indexed yet — may return no data or low-confidence score
- Payment failure — x402 $1 USDC payment not processed, returns 402
- Rate limiting or quota exceeded on self-serve tier
