# APAC Licensed-Entity Lookup

> Is company X licensed or registered by regulator Y? Searches 2643 entities on 9 official public registers: HKMA (authorized institutions, SVF licensees, approved money brokers), Japan FSA (crypto-asset exchanges, stablecoin/electronic payment instrument dealers, funds transfer providers, banks, financial instruments business operators) and Taiwan FSC (registered VASPs). Every answer carries the register source URL, as-of date and a not-legal-advice disclaimer. Also OFAC sanctions screening (SDN + Consolidated non-SDN lists from U.S. Treasury): crypto wallet address check (batch up to 25 addresses, BTC/ETH/TRX/USDT and more) and fuzzy name screening of entities, individuals, vessels and aircraft. Refreshed daily. Payment is USDC on Base (eip155:8453) via x402 v2, exact scheme. No account, no API key, no signup.

## How to pay

1. GET the endpoint and receive HTTP 402. The `PAYMENT-REQUIRED` header (base64 JSON) lists `accepts` (scheme exact, network eip155:8453, asset USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913).
2. Sign an EIP-3009 transferWithAuthorization for the amount and retry with the `PAYMENT-SIGNATURE` header. Any x402 v2 client works (for example @x402/fetch, agentcash).
3. The facilitator settles on-chain; you pay no gas.

### Alternative: MPP (Machine Payments Protocol)

The same 402 also carries a `WWW-Authenticate: Payment` challenge (method tempo, intent charge, USDC.e on Tempo (chain 4217), currency 0x20C000000000000000000000b9537d11c60E8b50), payable to the same address. Only pull-mode credentials are accepted (you sign, the server broadcasts) and the request is validated before broadcast, so a 4xx response never charges you. Any mppx client works, for example `npx mppx <url>`. The client pays its own Tempo network fee.

## Guidance

Use /v1/entities/search?q=<name, brand or registration/licence/corporate number>&jurisdiction=HK|JP|TW (optional register=<key>) to check whether a company appears on a covered register; matches include status, authorized flag, match_score, source_url and as_of. Then /v1/entity/{id} for the full register record and other registrations of the same company. Free coverage list (with not-covered registers to check directly): /registers. Japanese names match in Japanese; JFSA crypto-exchange entries also have English names. For counterparty screening: /v1/sanctions/address?address=<one or more comma-separated wallet addresses> (exact match against OFAC-listed digital currency addresses) and /v1/sanctions/name?q=<name>&type=entity|individual|vessel|aircraft (fuzzy). Coverage and list date: /sanctions/coverage (free). Not legal advice; verify with the regulator.
