# Japan MOF Sanctions Address Screening

> Japan MOF Sanctions Address Screening is a paid API for AI agents from api.agentfeeds.jp, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Screens a cryptocurrency address against Japan Ministry of Finance asset-freeze sanctions designations (外為法) and returns match status with designated-entity details.

## Facts

- Endpoint: GET https://api.agentfeeds.jp/v1/reg/sanctions/check
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/japan-mof-sanctions-address-screening-730b43d5
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_7NxAGFTqWUs7tfDXZJx1T

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 japan-mof-sanctions-address-screening-730b43d5
```

Example prompt: Can you check if the crypto address 0x1234abcd5678ef... is on Japan's Ministry of Finance sanctions list — I need to know if it's flagged under the asset-freeze designations before I process this transaction.

## When to prefer this

Use this endpoint when you need to screen a cryptocurrency address specifically against Japan's Ministry of Finance (MOF) asset-freeze sanctions list under the Foreign Exchange and Foreign Trade Act (外為法). Choose this over OFAC SDN screening when operating in a Japan-regulated environment or when Japanese regulatory compliance is required. Prefer this for per-address, real-time lookups rather than the sibling delta-feed endpoint which tracks day-over-day list changes.

## Known failure modes

- Address parameter missing or malformed — returns 400 bad request
- Address too short or too long (outside 20-100 alphanumeric range) — validation error
- Payment not included or insufficient — x402 payment required error
- Upstream MOF CSV unavailable — may return 503 or stale data indicator
- Unsupported address format — may return no-match rather than error

## How this service works
