## 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-batch-aml-screening-44cce118 -d '<json body>'
```

Example prompt: Screen these 30 Ethereum and Bitcoin wallet addresses for AML risk before I process payouts — flag anything suspicious using ChainAnalyzer's batch endpoint and tell me which addresses hit detection rules.

## When to prefer this

Choose this endpoint when you need to screen multiple wallet addresses simultaneously (2–50) to avoid the latency and cost of individual single-address calls. Ideal for AI agents processing payment batches, onboarding flows validating many users at once, or compliance pipelines that accumulate addresses before a sweep check. Prefer this over the single-address AML endpoint whenever you have more than one address to screen in the same workflow window.

## Known failure modes

- Batch size exceeds 50 addresses — request rejected with validation error
- Unsupported chain identifier for an address — individual address returns error while others process
- Invalid address format — malformed addresses flagged in per-address error fields
- Payment failure via x402 — full request rejected before processing
- Enterprise-only chains (BNB Smart Chain) accessed on non-Enterprise tier — chain not evaluated or error returned
- Rate limiting on concurrent batch requests — 429 or equivalent throttle response

## How this service works

Batch AML screening for multiple addresses (up to 50 per request). 8 live chains + BNB Smart Chain on Enterprise rollout, 76+ detection rules. Ideal for AI agents pre-validating wallet inputs at scale.

## Output

Returns AML screening results for each submitted address including risk scores, triggered detection rule identifiers, chain-specific findings, and an overall risk verdict — covering up to 50 addresses per call across 8 supported blockchains with 76+ detection rules evaluated per address.
