Example prompt: Can you check if the wallet address 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE is on the OFAC SDN sanctions list before I send funds to it?

## When to prefer this

Use this endpoint when you need a fast, low-cost ($0.001 USDC) OFAC SDN sanctions check on a single EVM wallet address before executing a crypto transaction, onboarding a user, or performing compliance due diligence. Prefer this over manual lookups or heavier KYC services when you only need SDN list screening for a blockchain address without full identity verification.

## Known failure modes

- Invalid or malformed wallet address (not 0x + 40 hex chars) returns an error
- Address not found returns a clean/no-match result
- OFAC data source temporarily unavailable returns a service error
- Missing address query parameter returns a bad request error
- Network timeout from the Cloudflare Worker
