## 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 ofac-sdn-batch-crypto-address-sanctions-screener-e7790463 -d '<json body>'
```

Example prompt: Before I send any funds, can you check these wallet addresses against the OFAC SDN sanctions list: 0x098B716B8Aaf21512996dC57EB0615e2383E2f96 and 0xd8da6bf26964af9d7eed9e03e53415d37aa96045?

## When to prefer this

Choose this endpoint when you need fast, batch crypto address screening specifically against the OFAC SDN list as part of an automated compliance workflow, pre-payment check, or on-chain transaction gate. It is particularly well-suited for AI agents, DeFi protocols, and Web3 payment processors that need machine-readable sanctions verdicts for multiple addresses at once without manual lookup. Do not use it as a substitute for full legal compliance review, for non-SDN sanctions lists, or for screening by name rather than address.

## Known failure modes

- Address string shorter than 20 or longer than 128 characters returns a validation error
- Batch exceeds 25 addresses — request is rejected
- Non-address inputs (e.g. ENS names or human-readable names) are not screened and will not match
- OFAC SDN list snapshot may be up to hours old — real-time changes won't be reflected immediately
- Only the SDN list is checked; OFAC non-SDN Consolidated lists and non-US sanctions lists are not covered
- A 'no match' result does not legally clear a counterparty — human review required for compliance decisions

## How this service works

An open index of the machine-to-machine (agent) economy. x402 routes: ranked discovery over the live x402 service market, every indexed service scored by real 30-day calls and paying-wallet bounds, with a receipt naming the snapshot hash and scoring revision. /economy routes, for Tempo MPP, Virtuals ACP, Olas, Masumi, ERC-8004 agent registries, Solana agent registries, Base agent contracts and MCP servers (Official MCP Registry): each protocol's published figures (agent or server counts, transactions or payment events; payers and USD volume only where the source publishes them: payers for x402 and Tempo MPP, USD volume for x402 and Virtuals ACP), each with its unit, window and source; units differ, so totals are not summed. L402 and per-service MPP listings are not covered.

## Output

A JSON object containing: the OFAC SDN list date used for screening, the screening method (exact address match), per-address results with match boolean, match type (exact_address or none), any SDN entity hits (including entity name, UID, type, chain, address, and sanctions programs), total match count, snapshot age in hours, source URL, and a compliance disclaimer. Addresses are normalized before comparison (0x and bech32 case-insensitive, base58 case-sensitive).
