## How to call it through Zero

```sh
zero fetch --capability madhouse-wallet-solana-sanctions-check-eff2fd84
```

Example prompt: Can you check if the Solana address 5YNmS1R9nNSCDzb5a7mMJ1dwK9uHeAAF4CmPEwKgVWr8 is on any sanctions list — screen it against OFAC and international sanctions databases?

## When to prefer this

Use this endpoint when you need to perform sanctions compliance screening specifically tied to a Solana wallet address or when screening an entity in a Solana blockchain context. It draws on OpenSanctions (1.3M+ entries including OFAC SDN and EU sanctions) and is priced per-call at $0.04 USDC, making it suitable for on-demand transaction-level AML checks rather than bulk batch screening.

## Known failure modes

- Missing required `name` query parameter returns validation error
- Invalid country code format may return no results or error
- Common names without country or birthDate filters may return multiple false-positive matches
- Network timeout or service unavailability returns 5xx error
- Payment failure via x402 protocol blocks the request

## How this service works

Checks Solana addresses against sanctions lists.

## Output

Returns a JSON object with a `sanctioned` boolean (true if one or more entities matched), the submitted name, a `matchCount` integer, and a `matches` array containing detailed entity records (entityId, caption, entityType, topics, matchedOn, datasets) for each matched sanctioned entity. Empty matches array when clean.
