## 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 x402-bazaar-compliance-check-31197407 -d '<json body>'
```

Example prompt: Run a compliance check on the address 0xAbC123...def456 — I need to know if it's OFAC-sanctioned, what its EOA or contract profile looks like, and whether it comes back blocked, flagged for review, or clear before I send any funds.

## When to prefer this

Use this endpoint when you need a single combined compliance verdict for a blockchain address — combining OFAC screening, address type profiling, and contract risk flags in one call — rather than querying separate sanctions APIs, block explorers, and risk scoring services individually. Ideal for compliance agents that need a deterministic blocked/review/clear output before authorizing a payment or interaction.

## Known failure modes

- 402 Payment Required — must pay $0.02 USDC on Base to the specified address and retry
- Invalid or malformed address input returns 400 error
- Address not found on-chain may return limited profile data
- Network timeout if Base RPC is congested
- OFAC list may have a propagation delay for very recent additions

## How this service works

Combined counterparty screening for an address: direct OFAC sanctions match, EOA/contract profile, and (for contracts) risk flags — rolled into a single recommendation (blocked / review / clear). Built for compliance agents. Paid via x402: $0.02 in USDC on Base (eip155:8453) to 0x973a31858f4d2125f48c880542da11a2796f12d6. Returns 402 with payment requirements; pay and retry.

## Output

A JSON object containing: a top-level recommendation of 'blocked', 'review', or 'clear'; a boolean or detail on whether the address directly matches OFAC sanctions lists; an EOA/contract profile indicating address type; and for contract addresses, specific risk flags that contributed to the recommendation.
