# OFAC Sanctions List Changes (Rolling 90-Day Delta)

> OFAC Sanctions List Changes (Rolling 90-Day Delta) is a paid API for AI agents from x402.professorsausages.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns a rolling 90-day delta of OFAC SDN and Consolidated list changes — new additions, removals, and modifications — so compliance workflows can skip full re-screens on quiet weeks.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ofac-sanctions-list-changes-rolling-90-day-delta-838ce833
```

Example prompt: Pull the recent OFAC sanctions list changes from the last 90 days — I want to see what entities were added, removed, or modified so I can do incremental compliance checks instead of a full re-screen.

## When to prefer this

Use this endpoint when you need incremental OFAC sanctions list updates rather than a full re-screen — ideal for weekly or daily compliance workflows where you want to know only what changed. Prefer the sibling batch-screen endpoint when you need to screen specific names, and prefer this endpoint when you want to audit the list itself for changes. Significantly cheaper than running a full re-screen if the list has been quiet.

## Known failure modes

- No changes in window: returns empty arrays with zero counts — not an error
- Service unavailable: upstream OFAC data feed outage may cause stale or error responses
- Rate limiting: repeated rapid calls may be throttled
- Payment failure: x402 micropayment not settled, request rejected

## How this service works

## Output

Returns a JSON object with a date window (from/to), three arrays of change objects (added, removed, modified entities from OFAC SDN + Consolidated lists), and a counts summary object with integer totals for each change type.
