## 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 kyb-brasil-batch-cnpj-sanctions-screening-3099c191
```

Example prompt: Can you run a sanctions screening on these Brazilian companies for me — CNPJs 12.345.678/0001-99, 98.765.432/0001-11, and 45.678.901/0001-55 — and tell me if any of them appear on the CEIS, CNEP, or CEPIM blacklists?

## When to prefer this

Use this endpoint when you need to screen multiple Brazilian CNPJs (up to 10) against sanctions databases in a single cost-efficient call rather than making individual per-CNPJ requests. It is ideal for batch supplier onboarding, AML portfolio reviews, or compliance sweeps where you want a single payment covering all items and inline per-item error reporting. Prefer the full KYB dossier endpoint if you also need Receita Federal registration and ownership details; use this batch sanctions endpoint when you only need blacklist status across a list of entities.

## Known failure modes

- Invalid CNPJ format causes a per-item error returned inline in results[]
- More than 10 CNPJs submitted results in a validation error
- All CNPJs fail lookup — call is not charged and returns an error
- CNPJ not found in Receita Federal records — returned as a per-item error
- Network timeout or upstream government database unavailability
- Payment not processed — x402 payment required before results are returned

## How this service works

Up to 10 CNPJs in one paid call (one payment, 25% off): br_sanctions_screen for each. Per-item errors are reported inline in results[]; the call fails (and is not charged) only when no item succeeds. Signed answer (Ed25519 attestation), verifiable at /v1/verify.

## Output

An array of per-CNPJ results, each containing the sanctions screening outcome (hit or clear) across Brazilian government blacklists including CEIS, CNEP, and CEPIM. Per-item errors are reported inline if a specific CNPJ lookup fails; the overall call is only charged if at least one item succeeds.
