```

Example prompt: Before I send funds, can you check if the address 0x7f268357A8c2552623316e2562D90e642bB538E5 is on the OFAC sanctions list?

## When to prefer this

Use this endpoint when an AI agent or automated system needs to perform real-time OFAC sanctions screening on a crypto wallet address prior to executing a transaction. This is especially critical for any DeFi, payment, or transfer workflow where regulatory compliance with US Treasury sanctions is required and the agent cannot query live government lists directly.

## Known failure modes

- Invalid or malformed address returns an error or no-match result
- Address format not recognized (e.g. non-standard chain format) may return an error
- Stale SDN list data if the underlying list source is not up to date
- Rate limiting or payment failure resulting in 402 or 429 response
- Network timeout or upstream data source unavailability

## How this service works

Check whether a crypto address appears on the US OFAC sanctions list before transacting - a compliance must-have for agents that LLMs cannot verify against live lists. ofac check, sanctioned address, sanctions screening, compliance check, blacklist address, sdn list Accepts payment on Base or Solana — either network works.

## Output

Returns whether the queried crypto address is flagged on the US OFAC SDN sanctions list, indicating whether the address is sanctioned or clear for transacting, along with any relevant match details.
