How this service works
Has anything changed about counterparties you already screened? Re-checks a list of addresses against OFAC designations and delistings since a timestamp you supply, so a verdict you acted on last month does not go quietly stale. Stateless: no watchlist is stored and nothing is sent to you — pass the returned checkedAt back as `since`. Free alternative: GET /v1/watch. Trial: 3 free calls/wallet/24h — https://trust-agent.io/v1/trial.
Output
Returns a JSON object with: a 'changes' array listing each address that moved (added to or removed from OFAC designations) since the supplied timestamp, with source, timestamp, and reason for each change; a 'feed' object describing the sanctions data source and its last sync time; a 'coverage' object indicating how far back the change log reaches and whether it fully covers the requested window (complete=false means a full re-screen is needed); and a 'checkedAt' Unix timestamp to use as the next 'since' cursor.
Example use cases
Daily compliance refresh for payment pipeline
“It's been 24 hours since we last screened our active counterparties. Re-check these 30 wallet addresses — 0xAbc1…, 0xDef2…, [etc.] — against OFAC sanctions for any designations or delistings since Unix timestamp 1714608000 on the Base chain, and give me the new checkedAt to store as tomorrow's cursor.”
Pre-settlement sanctions gate for DeFi protocol
“Before we settle this batch, re-screen these 12 counterparty addresses against OFAC for any changes since our last check at Unix timestamp 1715000000: 0x111…, 0x222…, 0x333…, 0x444…, 0x555…, 0x666…, 0x777…, 0x888…, 0x999…, 0xAAA…, 0xBBB…, 0xCCC… — flag anything that moved.”
Automated sanctions staleness detection for compliance audit
“Our compliance team needs to verify that none of the 20 wallet addresses we approved last quarter have been sanctioned since Unix timestamp 1706745600 — can you run the incremental OFAC change check on all of them and tell me if the coverage is complete or if we need to do a full re-screen?”
Technical details
Endpoint
GEThttps://trust-agent.io/v1/watch/addresses?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have already performed an initial full sanctions screen and need to detect incremental changes since a known timestamp — it is far more efficient than re-screening from scratch. Ideal for recurring compliance workflows (daily, hourly, or pre-settlement checks) where you store the previous 'checkedAt' as a cursor. Prefer the companion full-screen endpoint for first-time screening or when coverage.complete=false forces a baseline reset. Use this over a stored watchlist approach when you want stateless, on-demand change detection without server-side subscription management.
Side effects
- More than 50 addresses supplied — request rejected
- Unsupported chain value supplied (only 'base' is served) — request refused rather than answered from wrong chain
- coverage.complete=false — change log does not reach the supplied 'since' cursor, meaning a full re-screen is required to re-establish baseline
- Invalid or malformed EVM address in the list — may cause rejection or per-address error
- Trial quota exceeded (3 free calls/wallet/24h) — payment required or 402 returned
- Network timeout or feed sync lag causing delayed or stale response
