# EdgeScreen x402 — Data & Limits

Service: https://aso-x402-screen.asostudio.workers.dev/ (v1.7.0)

1. OFAC SDN Dataset & Refresh Cadence
- Source: 0xB10C/ofac-sanctioned-digital-currency-addresses (embedded-snapshot)
- Snapshot timestamp: 2026-11-14T00:00:00Z
- Indexed digital currency addresses: 1013 (EVM 0x..., Bitcoin Legacy/P2SH/Bech32, TRON T...)
- Scheduled refresh: every 6 hours via Cloudflare Worker cron trigger.

2. Deterministic Heuristics (Zero LLM)
- Impersonation, homoglyph, prompt-injection, SSRF URL, secret-leak, and git-diff checks execute deterministic rule engines (`llm: false`).
- Heuristic risk scores highlight technical indicators and cannot guarantee absence of novel attacks, unindexed sanctions designations, or false positives.

3. Not Legal or Compliance Advice
- Outputs are informational technical signals provided "as is" without warranty and do not constitute legal, regulatory, or sanctions-compliance advice.

4. Non-Custodial x402 Settlement
- Paid calls settle per request in Base Mainnet USDC (eip155:8453, $0.002 single-vertical / $0.005 batch) via https://facilitator.payai.network.
- Requests failing schema or batch validation are rejected with HTTP 400 before facilitator settlement.

5. Ephemeral Processing (Zero Payload Logging)
- Screened addresses, domains, prompts, URLs, secrets, and diffs are evaluated ephemerally in Worker isolate memory and are never persisted or logged.
