How this service works
Sanctions Delta ($0.008): which OFAC SDN entries (and OFAC-published crypto addresses) were added, removed, or modified since a given date, derived from OFAC's own official change-tracking feed (sanctionslistservice.ofac.treas.gov/changes/...) — not a self-diff of two snapshots. Body { since: "YYYY-MM-DD", entity_type?, crypto_only?, limit? }. Check free /v1/sanctions_delta/availability first.
Output
A list of OFAC SDN entry change records since the specified date, each indicating whether the entry was added, removed, or modified. Records include entity details (name, type) and, where applicable, OFAC-published crypto addresses. Filtered by entity_type and/or crypto_only if specified, up to the requested limit.
Example use cases
Crypto compliance wallet screening
“Pull all OFAC SDN crypto address changes since January 1, 2025 — I need to know which blockchain addresses were newly added or removed so I can update our wallet screening blocklist. Limit to 50 results.”
Daily sanctions monitoring for compliance team
“What new individuals or entities were added to or removed from the OFAC SDN list since yesterday? Show me up to 30 changes so I can brief the compliance team this morning.”
Vessel sanctions due diligence check
“I'm doing due diligence on a shipping deal — can you pull all OFAC SDN changes for vessels since March 1, 2025? I want to see any additions or modifications in the last couple of months, up to 60 results.”
Technical details
Endpoint
POSThttps://draconic21-x402-api.onrender.com/v1/sanctions_delta?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, officially-sourced OFAC SDN change data rather than self-diffing two snapshots — it derives from OFAC's own change-tracking feed. Ideal for compliance workflows that need to know exactly what changed since a specific date, crypto AML screening pipelines that need updated sanctioned addresses, or any agent that must detect newly sanctioned parties in near-real-time. Prefer over generic sanctions snapshot endpoints when delta/change tracking is the specific requirement.
Side effects
- Invalid or future 'since' date returns an error or empty result
- Unsupported entity_type enum value causes validation error
- limit out of range (below 1 or above 60) causes schema validation failure
- OFAC upstream feed unavailable causes service error
- No changes found for the given date range returns an empty list
- Rate limiting or payment failure (x402) blocks the request
