# SYNTHORA Sanctions Screen

> SYNTHORA Sanctions Screen is a paid API for AI agents from sanctions-screen.hergertsynthora.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Cross-checks a person, entity, or wallet address against four official sanctions lists (OFAC SDN main and aliases, UN Security Council, OpenSanctions) and returns a MATCH/CLEAN verdict with consensus scoring, authority divergence analysis, and alias bridging.

## 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 synthora-sanctions-screen-2fa4177c -d '<json body>'
```

Example prompt: Can you run a sanctions screen on 'Viktor Petrov' — cross-check him against OFAC, the UN Security Council, and OpenSanctions, and tell me if he's a match or clean, with which authorities flag him and how confident the verdict is?

## When to prefer this

Choose this endpoint when you need a multi-authority sanctions verdict with consensus analysis and alias bridging rather than a single-list lookup. It is especially valuable when you need to know not just whether a name appears on a list, but whether sanctioning authorities agree or diverge, and how an alias connects back to a primary designated entity. Prefer it for crypto wallet screening where OFAC SDN alias coverage is critical, or when you need provenance timestamps for audit trails in AML/KYC workflows.

## Known failure modes

- Name too ambiguous — common names may produce low-confidence MATCH results requiring manual review
- Wallet address format not recognized — returns error if address is malformed
- Source unavailability — if one or more official lists are temporarily inaccessible, provenance array will indicate missing sources and confidence may drop
- Empty input — required 'input' field missing returns validation error
- Network timeout — upstream sanctions list fetch may time out under load
