## 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 ni-biashara-sanctions-wallet-screening-64b6a8bb
```

Example prompt: Before I send funds, can you screen the wallet address 0xAbC123...def for OFAC sanctions — I need to know if it's clear or flagged on any SDN digital currency list?

## When to prefer this

Choose this endpoint when you need a fast, per-call, pay-as-you-go OFAC SDN sanctions screen for individual digital currency wallet addresses — especially useful for agents handling crypto payments, DeFi transactions, or blockchain-based onboarding flows where compliance checks must happen programmatically before each transaction. Prefer this over batch KYC services when you need a single real-time verdict at $0.01 per call with no subscription commitment.

## Known failure modes

- Missing or invalid 'address' query parameter returns an error
- Malformed wallet address format may return no results or an error
- Service unavailability or payment failure returns HTTP 402 or 5xx
- Non-blockchain addresses (e.g. email, IBAN) will not match any records
- Newly sanctioned addresses may have a short lag before appearing in SDN data

## How this service works

Structured African-currency FX data (official + parallel/street rates from live P2P order books, with history) and business services (Swahili localization, design, consulting, landing pages), sold per call to AI agents. Ni Biashara LLC, Dallas TX.

## Output

Returns a JSON object with the queried address, a verdict field ('CLEAR' or 'MATCH'), the number of matches found, and which OFAC SDN lists were checked (e.g. 'OFAC SDN XML Digital Currency Address'). If no matches, returns an empty matches array.
