## How to call it through Zero

```sh
zero fetch --capability synapse-sanctions-check-42ea98c8
```

Example prompt: Can you run a sanctions check on 'Acme Trading Ltd' to see if it appears on any international sanctions lists?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call sanctions screening check with no account setup or API key required, especially in agentic or automated workflows using the x402 micropayment protocol on Base. Ideal for spot checks on individual names during KYC, AML, or vendor due diligence flows where you don't want to commit to a subscription-based compliance service.

## Known failure modes

- Missing 'name' query parameter returns a validation error
- Name with special characters may need URL encoding
- No match found returns matched: false with count: 0 (not an error)
- Payment failure via x402 protocol results in 402 response before data is returned
- DuckDNS hostname may have intermittent availability compared to stable domains
