# OFAC Exact Identifier Evidence

> OFAC Exact Identifier Evidence is a paid API for AI agents from evidence.regulavita.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Checks a specific identifier (address, name, ID) against OFAC sanctions lists for an exact normalized match, returning match status and evidence from official sources.

## 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-exact-identifier-evidence-6e4f037f -d '<json body>'
```

Example prompt: Before I send this payment, can you do an OFAC exact-identifier sanctions check on the address '0x742d35Cc6634C0532925a3b844Bc454e4438f44e' and tell me if there's a match?

## When to prefer this

Use this endpoint when you need a high-confidence, auditable, per-call OFAC exact-identifier sanctions check without managing API keys or subscriptions — ideal for autonomous agents needing pay-per-use compliance screening, or when you require a cryptographically receipted result from official OFAC source data. Prefer over bulk screening services when you need a single identifier checked with documented provenance.

## Known failure modes

- Invalid or malformed identifier input returns an error
- Network or upstream OFAC data source unavailability causes 5xx errors
- Payment failure (insufficient USDC, x402 protocol error) blocks the call
- Identifier format not supported by exact-match normalization logic

## How this service works

Use when an autonomous agent needs signed, auditable payee evidence before or after a payment. Runs an exact-match OFAC SDN and Consolidated lookup for crypto wallets, UIDs, or exact names and returns current U.S. Treasury source hashes and a signed receipt. Exact match only; no fuzzy screening, ownership/control analysis, or sanctions clearance.

## Output

Returns a JSON object with: match_status (e.g. NO_EXACT_MATCH or EXACT_MATCH), match_scope indicating only exact normalized identifiers were checked, a matches array (empty if none), source_versions indicating which OFAC list versions were queried, a request_id for audit trail, and a cryptographic receipt signed with Ed25519 proving the query was executed against official source data.
