## 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 mekler-ai-ofac-sanctions-list-check-a9002687 -d '<json body>'
```

Example prompt: Can you screen 'Meridian Global Trading LLC' against the OFAC SDN and Consolidated sanctions lists and tell me if there are any potential matches or aliases?

## When to prefer this

Use this endpoint when you need a fast, automated heuristic screen of a name (and optional typed identifiers) against live OFAC SDN and Consolidated sanctions lists, especially in agentic compliance workflows, vendor onboarding, KYC pipelines, or pre-transaction checks. Prefer it over static/cached screening tools when freshness and source versioning (published dates and hashes) matter. Not a substitute for legal review or definitive identity verification.

## Known failure modes

- Source list retrieval failure — returns uncharged error if OFAC lists cannot be freshly fetched
- Name too short or too long — rejected if outside 2–160 character bounds
- Invalid request_id format — must match 16–64 alphanumeric/underscore/hyphen pattern
- Too many identifiers — maximum of 5 identifier objects allowed
- Ambiguous heuristic matches — similarity scoring may produce false positives requiring manual review
- No matches returned does not constitute legal clearance to transact

## How this service works

Match a supplied name and optional typed identifiers against freshly retrieved OFAC SDN and Consolidated lists. Return potential candidates, strong/weak aliases, matching evidence and versioned source dates/hashes. Similarity is heuristic; no identity, transaction-legality or clearance guarantee. 0.01 USDC per completed diagnostic; source/limit failures are uncharged.

## Output

Returns a verdict (e.g. 'potential_matches' or 'no_matches'), a list of match candidates with their list source (ofac_sdn or ofac_consolidated), match basis, and whether review is required, plus coverage metadata including source record counts, published dates, and a query-complete flag, along with an observed_at timestamp and limitation disclaimers.
