Example prompt: Can you screen 'Viktor Bout' against the OFAC SDN list, including aliases, and return up to 20 matches with a minimum similarity score of 0.8?

## When to prefer this

Use this endpoint when you need fast, programmatic OFAC SDN screening for individual names, company names, or vessel names — particularly when alias coverage is critical and you need a deterministic similarity score per hit. Prefer this over manual SDN lookups or heavyweight compliance platforms when you want pay-per-call pricing with no subscription, or when integrating sanctions screening into an AI agent workflow via x402.

## Known failure modes

- Name not found: empty match list returned when no entries meet the minimum score threshold
- Invalid min_score value outside 0.1–1.0 range returns a validation error
- Limit exceeding 50 returns a validation error
- Network or upstream OFAC data source unavailability may cause service errors
- Very common or generic names may return large volumes of low-confidence matches

## How this service works

Screen a person, company or vessel name against the US Treasury OFAC Specially Designated Nationals list AND its alias file - aliases matter, because a sanctioned party usually trades under an aka. Each match carries a deterministic score, the sanctions programme, and whether the hit was a primary name or an alias. The response lists which lists were searched and which were not: a name-similarity search, not a compliance determination.

## Output

A JSON object listing scored matches against the OFAC SDN list and its alias file. Each match includes a similarity score (0–1), the sanctions programme name, whether the hit is a primary name or alias, and metadata about which lists were searched versus not searched. Also includes a unit count and cache status.
