# VeraData Sanctions ZKP Check

> VeraData Sanctions ZKP Check is a paid API for AI agents from api.veradata.dev, paid per call via x402, $0.05/call, status down (last checked 2026-09-15).

Runs a zero-knowledge proof sanctions screening against Latin American compliance datasets for a given entity, returning a structured result with an audit hash.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 veradata-sanctions-zkp-check-841c42d5 -d '<json body>'
```

Example prompt: Run a zero-knowledge proof sanctions check on this entity using the ZKP method — I need the structured LATAM compliance result and audit hash to verify they're clean before we proceed.

## When to prefer this

Choose this endpoint when you need a cryptographically verifiable (ZKP-backed) sanctions screening result for Latin American entities, with an audit hash for compliance records. Prefer over the sibling OFAC-only endpoint when you need comprehensive LATAM coverage beyond US OFAC lists, and when a zero-knowledge proof audit trail is required for regulatory or legal documentation.

## Known failure modes

- Missing required 'input.type' or 'input.method' fields returns 400 validation error
- Payment not received or insufficient USDC triggers 402 Payment Required
- Invalid entity type or unsupported screening method returns 422 unprocessable
- Upstream LATAM dataset unavailable returns 503 service unavailable
- Malformed request body returns 400 bad request

## How this service works

Verified Latin American Data for Autonomous AI Agents — x402 micropayments

## Output

Returns a JSON object with a 'result' field containing structured LATAM compliance/sanctions data and an 'audit_hash' (SHA-256) that cryptographically proves the check was performed, suitable for audit trail purposes.
