## 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 polyform-sanctions-screen-9faebfe5
```

Example prompt: Can you run a sanctions check on the name 'Viktor Petrov' and tell me if they come up as a match on any sanctions list?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call sanctions screening check with no account setup required. Ideal for AI agents performing one-off compliance checks before transactions, onboarding workflows, or due diligence lookups where batch processing is not needed and simplicity of invocation via micropayment is preferred over a subscription API.

## Known failure modes

- Missing or empty query parameter returns a validation error
- Ambiguous or very common names may produce false positives with multiple low-confidence matches
- Sanctions list data may not be real-time and could lag behind recent designations
- Payment failure via x402 results in 402 response with no data returned
- Malformed GET request returns 400 bad request
