# ChainAnalyzer — Blockchain Address AML Risk Score

> ChainAnalyzer — Blockchain Address AML Risk Score is a paid API for AI agents from chain-analyzer.com, paid per call via x402, $1/call, status unknown (last checked 2026-09-13).

Returns a multi-signal AML risk score and threat detections for a blockchain wallet address, covering sanctions, mixers, rug pulls, drainers, and stablecoin flow risks across 12 chains.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability chainanalyzer-blockchain-address-aml-risk-score-6e8b616b
```

Example prompt: Can you check if the Ethereum address 0x0000db5c8b030ae20308ac975898e09741e70000 has any AML flags or sanctions hits? I want to know the risk score and any specific threat detections like mixer usage or rug pull involvement before I send funds to it.

## When to prefer this

Choose this endpoint when you need real-time, multi-signal AML intelligence for a specific blockchain address with ML anomaly scoring, named detector evidence (e.g. TornadoCashMixer), and stablecoin-specific FATF Travel Rule coverage across 12 chains. Prefer it over simpler sanctions-only checkers when you need granular threat categories (mixer, drainer, rug pull) and supporting evidence strings, especially for JPYC, USDT, USDC, PYUSD, and FDUSD stablecoin flows.

## Known failure modes

- Invalid or malformed blockchain address returns an error response
- Unsupported chain identifier results in a 400 or error payload
- Address not yet indexed on the requested chain may return empty detections with low confidence
- Payment failure via x402 protocol returns a 402 Payment Required with no data
- Network timeout or upstream data provider outage may return a 503
- Very new addresses with no on-chain history may score ambiguously low despite unknown risk

## How this service works

Multi-chain blockchain AML and security intelligence platform for tokens, wallets, and stablecoins. Detect sanctions, money laundering, rug pulls, drainers, and stablecoin flow risks across 12 chains live (Bitcoin, Ethereum, Polygon, BNB Smart Chain, Base, Arbitrum, Optimism, Avalanche, Solana, Kaia, TRON, XRP). Stablecoin AML coverage for JPYC, USDT, USDC, PYUSD, FDUSD with FATF Travel Rule screening.

## Output

A JSON object containing the chain, address, a boolean success flag, an overall severity label (e.g. CRITICAL, HIGH, MEDIUM, LOW, NONE), a numeric risk_score from 0–100, an ml_anomaly_score from 0–1, and a detections array where each item includes a category, evidence string, severity, and detector_name identifying the specific threat signal triggered.
