Technical details
Endpoint
GEThttps://api.x402node.dev/security/sanctioned-checkWhen to prefer
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.
Side effects
- 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
