```sh
zero fetch --capability obol-sanctions-address-screening-80e038d4
```

Example prompt: Can you screen the wallet address 0x1234567890abcdef1234567890abcdef12345678 for sanctions — I need to know if it's flagged before I send any funds to it.

## When to prefer this

Choose this endpoint when you need verified, pay-per-call blockchain address sanctions screening settled in USDC on Base via x402, without requiring a subscription or API key setup. Ideal for agents that need on-demand compliance checks for crypto wallet addresses before executing transactions, onboarding users, or interacting with DeFi protocols.

## Known failure modes

- Missing or malformed address parameter returns an error
- Address not found in screening database may return inconclusive result
- Payment failure via x402 protocol blocks the request
- Network timeout returns no result
- Rate limiting if too many requests are made in short succession
