## 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 websterberry-synaptic-ofac-nonprofit-screen-9caabe17
```

Example prompt: Can you screen 'Global Trade Solutions LLC' against the OFAC SDN sanctions list and also check if EIN 12-3456789 is a registered nonprofit?

## When to prefer this

Use this endpoint when you need to perform OFAC SDN compliance screening on a named individual or business — especially before onboarding vendors, making payments, or entering contracts. The optional EIN parameter makes it doubly useful when vetting nonprofits or charities, allowing both sanctions screening and IRS tax-exempt status confirmation in a single call. Prefer this over general-purpose web search for compliance use cases because it queries official government datasets (Treasury OFAC, IRS Publication 78) rather than unverified sources.

## Known failure modes

- Name not found on SDN list — returns clean/no-match result (not an error)
- Invalid EIN format — returns validation error for the EIN field
- EIN not found in IRS Publication 78 — returns not-found or non-exempt result
- Ambiguous name with many partial matches — may return multiple potential hits requiring manual review
- API unavailable or upstream data source timeout — returns error response

## How this service works

Screen a person or business name against the US Treasury OFAC SDN sanctions list (including aliases), and optionally confirm an EIN against IRS Publication 78 nonprofit data.

## Output

Returns whether the queried name (or business) appears on the OFAC SDN sanctions list, including any alias matches. If an EIN is provided, also returns the organization's IRS Publication 78 nonprofit status, confirming whether it is a recognized tax-exempt entity.
